MORPHOLOGICAL CHARACTERISTICS AND PRIMARILY PHYTOCHEMICAL INVESTIGATION OF SENNA ALATA
Main Article Content
Abstract
Background: Senna alata (L.) Roxb. (Fabaceae), which is a medicinal plant used generally in Vietnam as well as other countries. Many studies on the chemical composition and pharmacological effects of this herb have been carried out. Objectives: Description of micromorphological characteristics, preliminary analysis of phytochemical composition and analysis of isolated compounds by thin layer chromatography. Meterials and methods: Roots, stems and leaves of Senna alata were collected at Ho Chi Minh city, cut, stained, observed under optical microscope, and described. Preliminary analysis of phytochemical composition was performed by the Ciulei method. Isolated substances in previous study were determined by thin layer chromatography (TLC). Results: The microscopic characteristics of roots, stems, petioles, leaves and leaves powder were identified and presented in detail. Preliminary analysis of phytochemical composition revealed the presence of lipids, carotenoids, essential oils, free triterpenoids, anthranoids, flavonoids, anthocyanosides, tannins, saponins, reducing agents and polyuronides. Chromatograms of isolated compounds were detected under UV 254, UV 365 and vanillin-sulfuric reagent. Conclusions: Micromorphological characteristics together with the results of preliminary analysis of phytochemical and TLC contributes to the standardization of Senna alata.
