Abstract

Nowadays there is a renewed interest in crude drugs of plant origin, as they do not have side effects. Fluorescence analysis is a parameter to check the presence of bioactive molecules. The organic molecules absorb light usually over a specific range of wavelength and many of them re-emits such radiation known as luminescence. The phenomenon when re-emission of absorbed light lost only when the substance receiving exiting rays is called fluorescence. Such studies are of help in standardization of the plant material, which can be used as drugs. For the present study the plant Zizyphus jujuba belonging to family Rhamnaceae was selected and the fluorescence analysis of the leaves & fruits was carried as they are used as medicine. Leaves are simple, ovate or oblong or orbicular, petiolate with long petioles, serrate and entire margin, rounded at both the ends, slightly unequilateral at the base, glabrous, covered beneath with whitish or buff tomentum, tricostate reticulate venation, stipular spines usually in pairs and the fruit is a globose drupe.
