摘要

The current research was conducted in order to analyze bioactive compounds of the methanolic extract of the leaves of Cleisocentron pallens by using Gas Chromatography-Mass Spectrometry (GC–MS). Qualitative phytochemical screening was undertaken with the various solvent extracts of the leaf material; meanwhile GC–MS was conducted with the methanolic extract. The qualitative phytochemical screening showed the presence of different primary and secondary metabolites such as carbohydrate, proteins, alkaloids, flavonoids, saponins, tannins, terpenoids, steroids, glycosides and phenols. The GC–MS of methanolic extract of C. pallens showed the presence of 13 compounds that were mainly fatty acids and their derivatives, phytol and tocopherol. These substances are claimed to have many biological properties including antioxidant and anti-inflammatory properties. The results of this investigation document an initial knowledge about phytochemical makeup of the rare epiphytic orchid, C. pallens which could serve as the foundation for further pharmacological research.
