Tannin identification of 4 species pterydophyta from baluran national park

Abstract

Tannins are one polyphenol antioxidants which have higher molecular weight and having two ring aromatic group containing-OH. Antioxidant polyphenols in plants are potentially beneficial to human health as antibacterial, astringent, antidiarrheal, and antioxidant. The aim of this study was to identify tannins from 4 Pterydophyta species from Baluran National Park. This type of research is qualitative. The research sample consisted of rhizom and frond extracts of Pseudocyclosorus ochthodes, Dyopteris hirtipes, Phymatodes sp., and Pteris vittata. The extraction process was carried out using maceration method using 96% methanol and phytochemical screening was tested followed by TLC test. The results showed all samples were positive tannins and their Rf range were 0.62-0.86.
