Research on botanical characteristics and chemical composition of Selaginella sp. collected in Quang Ninh

Abstract

Selaginella species have existed for about 400 million years, demonstrating the evolutionary steps of vascular plants. In Vietnam, there are many species of this genus. To provide a basis for accurately determining the scientific name and surveying the chemical composition of a Selaginella species collected in Quang Ninh, the topic was conducted and used methods of describing external morphological characteristics, anatomical characteristics, chemical reactions, and thin layer chromatography. The results described the morphological and anatomical characteristics of the nutritional organs of the research sample and preliminarily concluded the classification position to the genus of this species. In addition, the presence of sterols, fats, glycosides, flavonoids, coumarins, anthranoids, saponins was also indicated. The chromatograms of the total extract and the sample fractions studied with the solvent system n-hexane and ethylacetate (5:1) also obtained good separation results, serving as a basis for further studies on chemical composition.
