SECONDARY METABOLITE PROFILE IN STEM AND ROOT OF KEJI PLANT (Staurogyne elongata (Blume) Kuntze)

Abstract

Keji plant (Staurogyne elongata (Blume) Kuntze) is an herbal medicinal plant that is often found on the islands of Java to Sumatra. The leaves and roots of keji plants (S. elongata) are used by the community as diuretic drugs and increase blood pressure and are believed to treat bladder stones, kidney stones, and joint problems. However, research on secondary metabolites in the stems and roots of keji plants has never been done. The aims of the study were to identify the secondary metabolites content and marker compounds in the stems and roots of keji plants. The research stages were drying and pollination of samples, extraction, and analysis using Gas Chromatography-Mass Spectrometry (GC-MS). The results showed that the compounds in the stem were nine secondary metabolite compounds from the phenol, terpenoid, alcohol and ester group. Meanwhile, secondary metabolite compounds in the roots of keji plants were ten compounds from coumaran, phenols, and ester group. The marker compounds in the stem were phenol, 2,2'-methylenebis[6-(1,1-dimethylethyl)-4-methyl- while the marker compounds in the roots were octadecanoic acid, 2-hydroxy-1-(hydroxymethyl)ethyl ester.
