Pharmacognostical and preliminary phytochemical evaluation of Jati patra (Jasminum grandiflorum Linn.)

摘要

The Jati patra ( Jasminum grandiflorum Linn.) b e lo n gs to t h e Oleaceae family. It is a widely gr o wn plant throughout India. It h as tikta, kashaya (bitter, astringent) rasa, ushna veerya (hot in potency), katu vipaka (pungent) and laghu (light), snigdha (unctuous), mridu (smooth) guna (properties). It is used for the management of Vrana (wounds), Mukha roga (oral cavity diseases), Netra roga (eye diseases), kustha (all types of skin diseases) etc. In spite of extensive utility, such study was not carried out. Hence, an attempt has been made to analyze it for its pharmacognostical and p re li m ina r y p h yt o-c hemical scree n ing by using different analytical tests. Transverse section of leaf shows, single layer of epidermal cells with unicellular trichomes, sta r ch grains, 10 to 14 stomatal cells, 16.5m stomatal index, 10 to 16 per sq. mm Vein islet and vein termination number an average of 15 to 16 per sq. mm palisade cells. Its leaf indicates maximum solubility in 90% Ethyl alcohol . Prelimina r y p h y t o- chemical analysis shows the p r esence of carbo h ydrates, tannins, sterols, fla v anoids, saponins, alkaloids , etc.
