ABSTRACT: Jasminum multiflorum and Jasminum mesnyi, the ornamental shrubs belonging to family Oleaceae are widely distributed throughout India. Despite their use in the essence industry for making perfumes, oils, and creams, these species are also used in the healing wounds and ulcers, constipation, flatulence, skin diseases, rheumatism, stomatitis, diabetes, stress, antiseptic, diuretics, and gastric disturbance. The present study is designed to establish the authenticity of both species by evaluating various standardization parameters. The stems of both species were collected and dried under shade. Freehand transverse sections were taken for microscopic examination. The standardization parameters such as Moisture content, Ash values, Extractive values, Heavy metal content, Aflatoxin content, Microbial infestation and, Pesticides residue have been determined as per WHO guidelines. Results showed the J. multiflorum stem was greenish-grey in color, cylindrical shaped, fragile and have aromatic odor. Microscopy showed the presence of glandular multicellular trichomes, epidermis, collenchyma, endodermis, medullary rays, vessels, xylem cells, parenchyma, fibre bundle and calcium oxalate crystals. The stem of J. mesnyi is yellowish-green in color the surface is smooth and pubescent. The epidermis, collenchymas, endodermis, medullary rays, xylem cells, vessels, trichomes and parenchyma are also present in the microscopy. Preliminary phytochemical screening of both plants confirmed the presence of alkaloids, anthraquinone glycosides, saponins glycosides, cardiac glycosides, flavonoids, steroids, terpenoids, tannins, and phenolic compounds. The analysis of Heavy metal, Aflatoxin, microbial contamination and pesticide residual values were found within limits. The result of our study confirmed the authenticity of both the species and the parameters studied can be used in the future as a part of the monograph.

INTRODUCTION: Ayurveda is one of the most renowned traditional systems of medicine that has survived and flourished for ages to date. In the modern time, when the allopathic system of medicine has reached almost the top because of validated research and advanced techniques still herbal medicines are the choice of drug for several chronic diseases such as cancer, diabetes, arthritis, and asthma. The various species of the genus Jasminum are used by people for their effectiveness.
The genus Jasminum belongs to the Oleaceae family having 200 species throughout the world and out of which around 40 species are native to India 1. Jasminum multiflorum is also known as winter jasmine or musk jasmine; which is an ever green winner shrub with young branches dressed with velvety pubescence. Jasminum mesnyi, well known as Yellow jasmine, is a perennial shrub 2, 3. Being known for there fragrances, the flowers are used in aromatherapy for uplifting the mood. Both the species are found throughout India, in the forests of Western Ghats, sub- Himalayan tracts up to 1300-1500 meters altitude and are also cultivated as garden plant 4. Traditionally these plants are used to treat a variety of ailments like treat anxiety, anorexia, diabetes, depression, gastric disturbance, muscular pain, nocturnal emission, oral sores, stress, ulcer, uropathy, cephalalgia, cardiac disorders, constipation, indigestion, inflammation, rheumatism, lactifuge, weakness of sight, and snake bite 5-9.
The various secondary metabolites namely alkaloids, glycosides, flavonoids, steroids, terpenoids, tannins and saponins are substantiated in different parts of the plants 5, 10, 11. The pharmacological studies proved their efficacy in J. multiflorum towards antioxidant 12, 13, antimicrobial 14, antihelmintic 15, nemacitidal 16, GI 17, in cardiovascular diseases 18, 19 and effect on central nervous system 20, 21 and J. mesnyi revealed its wound healing potential of roots 22, antioxidant 23, 24, antiulcer 25, antihyperglycemic 26, antihelmintic 27 and antimicrobial 28 efficacy of leaves were substantiated. The main hindrance to the acceptance of herbal medicines is the lack of documentation and quality control. The establishment of pharmacognostic standards for the traditional plants is a prerequisite for its detailed phytochemical and pharmacological investigation. The present study was done for establishing pharmacognostic and physicochemical standards of the plant stem as per WHO Guidelines which will further help in drug identification as well as in detecting/establishing adulteration.
MATERIALS AND METHODS:
Plant Collection and Authentication: J. multiflorum and J. mesnyi stems were collected from the Botanical Garden of Hindu College of Pharmacy, Sonipat. The plants were authenticated by Dr. Sunita Garg (Emeritus Scientist, CSIR- NISCAIR, and New Delhi, India). The voucher specimen(NISCAIR/RHMD/CONSULT/2018/3296-97-1 and 3296-97-2 for J. multiflorum, J. mesnyi respectively) was deposited in the Department of Pharmacognosy, Hindu College of Pharmacy, Sonepat for future reference. The plant materials were dried under shade by placing in a single layer and coarsely powdered by hand mixer and pass through sieve no #60.
Macroscopy: Untreated powdered samples were observed under daylight and the color of samples was recorded. The powder was rubbed slowly between fingers and odor was examined. Tastes of the powder were also observed. The surface was examined by softly touching it 29.
Microscopy: The thin transverse sections of both fresh stems were cut with the help of a sharp blade and cleared with chloral hydrate solution. Freehand sections was stained with phloroglucinol, ruthenium red, safranin and hydrochloric acid and further mounted in glycerine and covered with coverslip. For powder microscopy, the powder of stems was passed through sieve no # 60 and taken on glass slides. The same procedure was followed as mentioned above to prepare the slides. The slides were observed under a compound microscope and photographs were taken using Labomed ATC- 2000 microscope attached with camera 29-32.
Qualitative Analysis: The procedure recommended by Indian Pharmacopoeia was used for determining the total ash, water-soluble ash, acid insoluble ash, water-soluble extractive, ethanol- soluble extractive, loss on drying, swelling index, crude fibre content and foaming index 29-32, where as aflatoxin content, microbial contamination, heavy metal analysis and pesticidal residues were evaluated according to WHO guidelines 32. A fluorescence study was performed as per standard procedure 29, 33.
Preliminary Phytochemical Screening: For the preliminary phytochemical screening, extracts of both species were prepared according to the polarity of the solvents (petroleum ether, chloroform, ethanol and aqueous) as per the standard procedure. The preliminary phytochemical screenings of extracts were performed according to standard procedure 29, 33.

DISCUSSION: Despite the availability of various analytical tools in the field of modern pharmaceuticals, still lacking pharmacognostical standards for traditionally used plants is the major lacuna. Precisely for the reason, the WHO has recommended various physicochemical methods for authentication of plant drugs. These parameters can even help in the detection of adulteration hencethey should be adopted to confirm the identity, purity, and quality of plant drugs 34.
Macroscopic parameters viz., color, taste, texture, odour, size and shape are helpful for the identification of plant materials So, quality control of herbal drugs has traditionally been done based on appearance or morphological evaluation; but today microscopic evaluation is indispensable in the initial identification of herbs, as well as in identifying small fragments of crude or powdered herbs, and detection of foreign matter and adulterants. Physicochemical parameters are important parameters in detecting adulteration and are adopted to confirm the identity, purity, and quality of the drug. Ash values are particularly important parameters as these show the presence or absence of foreign matters like metallic salts and silica etc. The values of total ash, water-soluble ash, and acid-insoluble ash are 3.92%, 1.75% and 1.28% (J. multiflorum) and 4.56%, 2.34% and 1.66% (J. mesnyi). Loss on drying for both the stem was nearly 5.73% and 6.54% respectively.
It signifies the considerable amount of moisture in the stem. The moisture content of a drug should below in order to prevent decomposition of crude drug either due to chemical change of constituents or microbial contamination. The result of fluorescence analysis of stem powder showed their characteristic fluorescent color in different organic and inorganic solvents. The fluorescence behavior of powdered drugs plays a vital role in the determination of the identity, quality, and purity of the drug material.
Extractive values are primarily useful for the deter-mination of exhausted or adulterated drugs. The result suggests that the drug has high ethanol-soluble extractive value compared to water-soluble extractive value. Preliminary Phytochemical Evaluation showed the presence of alkaloids, glycosides, saponins, steroids, terpenoids, flavonoids, carbohydrates, protein and amino acid, tannins and phenolic compounds in the stem of both plants. Heavy metal like mercury is not detected in any of the species however the level of cadmium, arsenic and lead are within the limits as per WHO guidelines. The results of microbial content, aflatoxin content, and pesticide residue revealed that both species are free from above the natural contaminants and therefore used for the preparation of formulation 34.
CONCLUSION: Standardization studies help in identification, authentication and establishing the quality of the plant material and will be useful in preparing a monograph of the plant. Further, it will act as a tool to detect adulterants and substituents and is helpful in maintaining the reproducibility of quality and efficacy of natural drugs.
