Pharmacognostical and Preliminary Phytochemical Investigation of Launaea Sarmentosa (Willd.) Sch. Bip. ex Kuntze

Author: UPLOADED BY-ADMIN, ARON S, SIVA V, MEHALINGAM P
Abstract: The present study deals with the macroscopical and microscopical studies of Launaea sarmentosa (Willd.) Sch. Bip. ex Kuntze leaf, stem and root. The anatomy of the leaf, stem and root were studied by taking transverse section. The leaf ground tissue was homogenous and parenchymatous with wide, angular, thin walled compact cells. Stomata occur on both surface of the lamina, anomocytic type stomata. The stem vascular cylinder was wide, circular and hollow. It consists of about thirteen wedge shaped vascular strand which alternate with narrow sclerenchymatous interfacicular segments. Wide circular laticiferous canals were seen in the pith. The root consist of secondary phloem has wide dilated rays and scattered sieve elements, some of which were collapsed into dark masses. Secondary xylem consists of diffusely distributed dense vessels and thick walled, lignified xylem fibres. Various parameters like powder analysis, fluorescence analysis, physicochemical constant and phytochemicals analysis were studied. These observations would be of immense value in the botanical identification and standardization of the drugs in the crude form. This study would help to distinguish the drugs from its other species.
