Obat Pahit is a potion that has been long commonly consumed by Lingga Malay society for generations as stamina keeper. The most dominant plants found in the packaging of the Obat Pahit were namely Bauhunia semibifida, Cnestis palala and Penawa Root (3 species). This research aimed to investigate and determine activity of antioxidant contents in Obat Pahit from five Traditional Medicine Practitioners (TMPs) in the district of Lingga. The tested samples were mashed then being soaked into 2 types of solvent: distilled water and methanol, containing HCl 1%. DPPH method was also used in this research. Quantitatively antioxidant activity test of Obat Pahit from the five TMPs by using methanol solvent had extremely highest activity compared to the distilled water solvent. The test, using TLC plate by spraying the extract from three dominant plants with 0.1 mM of DPPH solution, produced a pale-yellow spots at a wavelength of 366 nm. On the other hand, the test using HPLC at wavelengths of 230 nm and 280 nm showed the presence of two dominant secondary metabolites contents: flavonoid and phenolic. IC50 (ppm) of Bauhinia semibifida (6.6247), Penawa Root (5.0124) and Cnestis palala (5.9968) were much lower than IC50 of mangosteens rind (41.7675), vitamin C (6.6612) and Stimuno drug (8.333). This antioxidant analysis has not been reported previously. This proof contributed greatly to uncovering potentially native natural resources as an indigenous Indonesian drug which is expected to decrease dependence on imported drugs especially imunomodulator, antihypertensive, antidiabet etc. This research would be beneficial and excellent manifestation for the development of natural antioxidant-based medicines from traditional knowledge of Indonesias local ethnicities.

Metode yang digunakan dalam penelitian ini adalah metode deskriptif, wawancara dan survey langsung di lapangan. Hasil penelitian menunjukkan ada 250 jenis tumbuhan obat yang digunakan oleh suku Sakai yang berasal dari Desa Sebangar dan Desa Kesumbo Ampai. Berdasarkan familinya kelompok Zingiberaceae lebih banyak digunakan di Sebagar, sedangkan Famili Annonaceae lebih banyak digunakan di Desa Kesumbo Ampai. Berdasarkan bagian tanaman yang digunakan daun merupakan organ yang paling bayak digunakan di kedua tempat, sedangkan berdasarkan habitus tumbuhan berhabitus pohon lebih umum digunakan di kedua tempat.Indonesia have the high natural resources and biodiversity with 13.466 islands in 33 provinces with various of ethnics and cultures. The high plant diversity combined with the variety of ethnics might result in the diversity of knowledge system of relationship between the society cultures and their plants cultures. The traditional treatment cultures and use the medicinal plants have been evolving for centuries that have been conserved from generation to generation. The presence of culture modernization has caused erosion of traditional knowledge of the society especially in the medicinal plants knowledge of Sakai Duri and Duri 13 ethnics. The aim of this study was to collect the information about the medicinal plant knowledge in Sakai ethnic. This study used descriptive method to collect all informations about the medicinal plant knowledge. The study has found 250 species of medicinal plants used by Sakai ethnic in Sebangsar Village and Kesumbo Ampai Village. Based on the family, the plants from Zingiberaceae family have been used more intensively by the society of Sebangar village, whereas the plants from Annonaceae family have been used more intensively by the people in Kesumbo Ampai village. The organ or part of the plants that is mostly used in both village was leave organ/part. Based on the habitus, the trees are mostly used in both sites and there were 35 tree species used in Sebangsar village compared to 42 species in Kesumbo Ampai village.
