Determination of Marker Compounds of Senna alata from different location in East Kalimantan, Indonesia

Abstract

Senna alata is a plant used for medical purposes, and its leaves have an extended history of use as a traditional herbal medicine in Indonesia. S. alata is known to contain some components of biologically active compounds and also secondary metabolites. In fact, S. alata can grow well in various locations in Indonesia, location differences can lead to differences in compound content due to differences in environmental conditions such as soil, rainfall, light intensity, and humidity. Therefore, this study aimed to analyze marker compounds of S. alata plants origin from three different location in East Kalimantan, i.e Samarinda, Samboja, and Berau. This research was conducted to estimate the compounds contained in extracts by using GC-MS analysis, and to discover relationships between different variables by using Principal Component Analysis (PCA). There are variances in the yield of secondary metabolites according on where Senna alata is grown, specifically in the riverside Nyapa Indah region and the plains of Samarinda and Samboja. Based on GC-MS test results, Phytol was the main compound in S.alata in two areas, i.e. Samarinda and Samboja. Meanwhile, in Berau showed that 1,2-Benzenedicarboxylic acid, and mono (2-ethylhexyl) ester were the main components. However, S. alata leaf extracts could be used as a good quality raw material for pharmaceutical industries, such as a laxative agent.
