| Abstract | This study aims to determine the phytochemical screening, total phenolic contents, and antioxidant activity of leaf and shoot extracts of Dendrocalamus membranaceus and Thyrsostachys siamensis. Each part of plant was extracted by boiling with distilled water in the solid to liquid ratio of 1 to 5 for 30 min twice. Phytochemical screening involved the methods to detect the presence of alkaloids, flavonoids, saponins, tannins, cardiac glycosides and triterpenoids. Total phenolic contents were estimated with gallic acid as standard. Antioxidant activity was determined using 2, 2'-azino-bis (3-ethyl benzthiazoline-6- sulfonic acid) (ABTS) and 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assays. The result showed that flavonoids and saponins were presented in the aqueous extracts of both leaf and shoot of D. membranaceus and T. siamensis. Total phenolic content was the highest in shoot extract of D. membranaceus and the lowest in leaf extract of D. membranaceus. The leaf extract of D. membranaceus exhibited the highest antioxidant activity in ABTS and DPPH assays, with 24.0 and 503.0 ?g/ml, respectively, and was higher activity than its shoot extract. |
