Antimicrobial resistance has become a global health crisis, leading to increase morbidity, mortality and health care costs. Antibiotic resistance is a growing global health concern. Overuse and misuse of antibiotics have led to the emergence of bacteria that are resistant to many commonly used drugs. Natural plant-based medicines offer an alternative approach to combat infections, as they contain various bioactive compounds that can effectively inhibit the growth of bacteria, fungi, viruses, and other microorganisms. This study describes a procedure for retrieving the ethanol, chloroform, and aqueous extracts from the bark samples of Sample A - Pum Kutaja (Holarrhena antidysenterica [Linn] Wall ex.G.Don) and Sample B - Stri Kutaja (Wrightia tinctoria R.Br) testing them against a variety of microorganisms, both Gram-negative bacteria Vibrio cholerae (MTCC 3906), Pseudomonas aeruginosa (ATCC 27853), Escherichia coli (ATCC2592), and Gram-positive bacteria Streptococcus pneumoniae (MTCC 655), Staphylococcus aureus (ATCC 29213) and fungus Candida albicans (MTCC 227) for antimicrobial effect.

Introduction

A drug is defined as any substance used for the purpose of diagnosis, prevention, relief or cure of a diseases. According to W.H.O. the drug is a substance used in the diagnosis, treatment, or prevention of a disease or as a component of a medication. Microbial infections have been point of serious concern. Moreover the problem of drug resistance has multiplied its magnitude many fold. In the present study an effort was made to screen potential herb against diseases caused by microbes and to highlight their potential against resistant microbes. Ayurvedic classics deal different procedures and medication to treat the Atisaar (Diarrhea) and Krimi. Kutaja is one such medicinal herb which has the potential to treat diarrhea caused by Krimi and so was selected for the study. Pum Kutaja (Holarrhena antidysenterica[Linn] Wall Ex G.Don) belongs to Apocyanacea family. It is tree with simple and opposite leaves. Phytochemically the bark contains Holarrifine, Kurchamide, Kurcholessine. Pharmacogonostically have antiamnesic, Neuroprotective activity, Acetylcholinesterase inhibitory, Antidiabetic activity. Propagation is done by Air layering, root sucker, seed. Stri Kutaja (Wrightia tinctoria R.Br) belongs to Apocyancea family. It is tree with simple and opposite leaves. Phytochemically the bark have Lupeol, Stigmasterol, Compestrol. Pharmacogonostically have antipsoriatic, antihelminthic, antidiabetic, wound healing property. Due to its Krmighan, Grahi properties, easy availability, cost effectiveness and low dose required for its therapeutic effect the drug was evaluated for its therapeutic use. Pum Kutaja (Holarrhena antidysenterica[Linn] Wall Ex G.Don) have Katu, Tikat Rasa and Sita Virya while in case of Stri Kutaja (Wrightia tinctoria R.Br) have Katu, Kashya, Tikat rasa and Ushna Virya both have Atisarghan property as mentioned in Raja Nighantu.^[1] In Susruta Samhita, Utar Tantra Krimi is mentioned as Nidana of Atisara (Diarrhea).^[2] In Kaiydev Nighantu the Kutaja and the other variety of Kutaja has been told which has Jantuhar and Atisaarhar property. Jantu is one of the synonyms for Krimi and so the Pum Kutaja (Holarrhena antidysenterica[Linn] Wall Ex G.Don) and other variety i.e., Stri Kutaja (Wrightia tinctoria R.Br) can be considered here to have Krimihar i.e., antimicrobial property. As both the variety of Kutaja have Atisaarghan property so study was

undertaken to see and compare the antimicrobial efficacy of both the drugs and to conclude that which drug has better action.

In Indian Materia Medica, Pum Kutaja (Holarrhena antidysenterica[Linn] Wall Ex G.Don) whole plant is used for Acute, Chronic dropsy, menorrhagia and Dyspepsia⁽³⁾. In case of other varity Wrightia tinctoria flowers have fragrance. Bark is of reddish brown colour and smooth appearance as compared to (Holarrhena antidysenterica[Linn] Wall Ex G.Don). In Wrightia tinctoria seeds, the tuft is on the end next to the foot stalk.^[4]

In Indian Medicinal Plant, Pum Kutaja (Holarrhena antidysenterica[Linn] Wall Ex G.Don) bark is bitter, dry, pungent and as antihelminthic, antidiarrheal properties and alleviates dysentery, fever, piles, leprosy, skin diseases.^[5] In other variety Stri Kutaja (Wrightia tinctoria) bark and seed have the same properties as those of (Holarrhena antidysenterica[Linn] Wall Ex G.Don). They also mentioned that bark is especially useful in piles, skin disease and biliousness.^[6]

The Wealth of India quotes Pum Kutaja (Holarrhena antidysenterica[Linn] Wall Ex G.Don) bark (Kurchi) has astringent, antidysenteric, anthelmintic, stomachic, febrifugal and tonic properties.^[7] It is used in the treatment of amoebic dysentery and diarrhea. The total value of Kurchi- the common word used for bark is due to presence of alkaloids which occur as tannates. In case of Stri Kutaja (Wrightia tinctoria) the bark is commonly used as an adulterant of the well known drug Conessi, Tellicherry or Kurchi bark which is obtained from (Holarrhena antidysenterica[Linn] Wall Ex G.Don).^[8]

The microbe taken for the study i.e., Vibrio cholera, Escherichia coli, Staphylococcus aureus, Psuedomonas aeruginosa, Candida albicans, Streptococcus pneumonia causes diarrhea indicating Sukshmata (minuteness), Adrishyata (not visible by naked eye), Krimija Nidana (microbes causing diarrhea) and Vaikarikta (pathogenicity of microbes) of Krimi. Hence their antimicrobial study was done.

Vibrio Cholerae - A Gram negative bacteria, 1.5 x 0.2- 0.4 µm in size, motile in nature causes the infections in human beings by ingestion of contaminated foods and drink. The ingested organisms pass through the acid barrier of the stomach and multiply in the alkaline medium of the small intestine and responsible for diarrhea.^[9]

^[10]

E.coli - A Gram negative bacteria 1-3 x 0.4- 0.7µm in size, motile in nature is transmitted by the fecal- oral route. Pili - a structure in the intestine allow the bacteria to colonize the ileal mucosa. Cytotonic enterotoxins induce watery diarrhea. Plasmid - encoded invasion factors permit invasion of the mucosa and induce tissue damage, the presence of either of these factors induce a host inflammatory reaction with an influx of lymphocytes and resulting diarrhea.

Staphylococcus aureus - A Gram positive bacteria which ferment on sugar media and causes food poisoning which is an intoxication that result from consumption of food containing sufficient amount of enterotoxins which lead to nausea vomiting and diarrhea.^[11]

Pseudomonas aeruginosa - A Gram negative bacteria 1.5 x 0.5µm motile bacteria also produce enterotoxin which is responsible for diarrhea.^[12]

Candida albicans - 3-5µm diameter oval in shape, has motility causes diarrhea.^[13]

Streptococcus pneumonia - A Gram Positive, 1µm in diameter causes diarrhea.^[14]

As stated above that Krimi are found in abdomen have motility, one of the causative factor for the Atisaar so all these microbes were taken for study.

Materials and Methods

Stem bark of Sample A & Sample B was collected and washed and shade dried and fine powder was done and stored in air tight container.

Preparation crude extract

Different solvents ethanol, chloroform, Aqueous were chosen for successive solvent extraction based on polarity using Soxhlet extraction apparatus and the extract of Sample A - Pum Kutaja (Holarrhena antidysenterica[Linn] Wall ex.G.Don) & Sample B - Stri Kutaja (Wrightia tinctoria R.Br) were concentrated under reduced pressure under rotator evaporator. The procedure were done HHrc, Amritsar (Fig no. 1,2,3,4).

Dilution of extract

DMSO was used for dilution of ethanol, chloroform and aqueous extract of bark samples of Sample A - Pum Kutaja (Holarrhena antidysenterica[Linn] Wall ex.G.Don) and Sample B - Stri Kutaja (Wrightia tinctoria R.Br).

Test Microorganism

The Microbial Type Culture Collection and Gene Bank (MTCC) stains of Vibrio cholerae (strain no 3906), Streptococcus pneumoniae (strain no 655), and Candida albicans (strain no 227), were procured from CSIR- IMTEC, Section 39, A, Chandigarh.(Fig No.5).American Type Culture Collection (ATCC) strains of Staphylococcus aureus(ATCC 29213), Pseudomonas aeruginosa (ATCC 27853) and Escherichia coli (ATCC 2592) were procured from Department of Microbiology, Governmental Medical College, Patiala and were used for present study.

Preparation of Media: Mueller-Hinton Agar (MHA), which is the best medium for routine susceptibility tests was used for the antimicrobial study in the department of microbiology GMC, Patiala.

Disc Diffusion Method

The Antimicrobial activity was studied using disc diffusion method. The following steps were taken:

Antimicrobial Disks Preparation

The disk diameter was approximately 6 mm were punched out of Whatmann paper no 1 following which were sterilized in the hot air oven at 160° C for 2 hrs. The disks used for the study were impregnated with leaf extracts of ethanol, chloroform and aqueous extract diluted with DMSO₄ of bark samples of Sample A - Pum Kutaja (Holarrhena antidysenterica[Linn] Wall ex.G.Don) and Sample B - Stri Kutaja (Wrightia tinctoriaR.Br).

Inoculation of Plates

1. A sterile cotton swab was dipped into the standardized bacterial suspension.
2. The excess inoculum was removed by lightly pressing the swab against the tube wall at a level above that of the liquid.
3. The agar was inoculated by streaking with the swab containing the inoculum.
4. The plate was rotated by 60° and the rubbing procedure was repeated two times. This ensured an even distribution of the inoculum.
5. The surface of the medium was allowed to dry for 3-5 minutes but not longer than 15 minutes to allow for absorption of excess moisture.

Application

1. Using sterile forceps or disk dispenser (disc

impregnated with extract of different disc of Sample A & Sample B) were placed on the surface of the plate inoculated with different bacterial and fungal strains.
2. It was ensured that the disks were not moved once they had come into contact with the agar surface since some diffusion of the drug occurs instantaneously.
3. A maximum of six disks may be placed in a 9-cm petri dish.
4. The plates were incubated in an inverted position at 37°C.
5. Different zone of inhibition was observed and recorded after 16 to 18 hours using graduated ruler.

Results

Zone of inhibition Vibrio cholera, Escherichia coli, Staphylococcus Aureus, Pseudomonas aeruginosa, Streptococcus pneumonia, Candida albicans against different concentration are listed in Table No. 1,2,3,4,5,6 & Fig No. 5,6,7,8,9,10 respectively.

Discussion

Among all three extracts of Pum Kutaja (Holarrhena antidysenterica[Linn] Wall ex.G.Don) i.e., Aqueous, ethanol and chloroform, ethanol extract shows maximum sensitivity against all the tested microbes, then Chloroform extract and then aqueous extract. The antimicrobial activity was maximum in case of Vibrio cholera and rest of the organism shown the order like - Vibrio cholera> Escherichia coli> Staphylococcus aureus> Pseudomonas aeruginosa> Candida albicans> Streptococcus pneumoniae

The similarly results were found in all three extracts of Stri Kutaja (Wrightia tinctoria R.Br). The antimicrobial activity was maximum in case of Vibrio cholera and rest of the organism shown the order like - Vibrio cholera> Escherichia coli> Staphylococcus aureus> Candida albicans> Pseudomonas aeruginosa> Streptococcus pneumoniae

Although Pum Kutaja (Holarrhena antidysenterica

[Linn] Wall ex.G.Don) showed markedly increasingly sensitivity for all the tested microbes in 10 to 30µl as shown in Table no. (6, 8,10). Similarly in case of Sample B - Stri Kutaja (Wrightia tinctoria R.Br) results are shown in Table no. (7, 9, 11).

On comparing zones of inhibition of both the samples of bark i.e. Sample A - Pum Kutaja ( Holarrhena antidysenterica[Linn] Wall ex.G.Don) and Sample B - Stri Kutaja (Wrightia tinctoria R.Br) three different extracts i.e., aqueous, ethanol and chloroform extracts, Sample A - Pum Kutaja (Holarrhena antidysenterica [Linn] Wall ex.G.Don) showed more antimicrobial sensitivity against all tested pathogens i.e. Vibrio cholera, Escherichia coli, Staphylococcus aureus, Pseudomonas areuginosa, Streptococcus pneumoniae than Sample B - Stri Kutaja (Wrightia tinctoria R.Br). But in case of Candida albicans, Sample B - Stri Kutaja (Wrightia tinctoria R.Br) showed more sensitivity than Sample A - Pum Kutaja- (Holarrhena antidysenterica[Linn] Wall ex.G.Don). There is no activity seen in 10, 20,30µl of Sample A & Sample B for aqueous extract in case of Streptococcus pneumoniae. Similarly in case of Ethanolic, Chloroform extract there is no activity seen in 10µl of Sample A& B for Streptococcus pneumoniae.

Conclusion

Results showed that both the plants Pum Kutaja (Holarrhena antidysenterica[Linn] Wall ex.G.Don) and Stri Kutaja (Wrightia tinctoria R.Br) were found to have antimicrobial activity against tested microbes. Pum Kutaja (Holarrhena antidysenterica[Linn] Wall ex.G.Don) and Stri Kutaja (Wrightia tinctoria R.Br) can be used as an antimicrobial and antifungal agent against different pathogens. They can be used against Gastrointestinal and skin infections. Both the plants could effectively be used as best natural alternative to synthetic antimicrobial agents. On comparing both the plants Pum Kutaja (Holarrhena antidysenterica[Linn] Wall ex.G.Don) was found to be more potent action against microbes causing diarrhea than Stri Kutaja (Wrightia tinctoria R.Br).
