PHYTOCHEMICAL AND PHARMACOGNOSTICAL SCREENING OF JASMINUM MULTIFLORUM (BURM. F.) AND JASMINUM MESNYI (HANCE) STEMS

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.
