Abstract

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.

Abstract

Obat pahit has been generally known and believed by Lingga Malay society as anti-aging agent. However, the study of Obat pahit is not scientifically proven. This research was aimed to prove immunomodulatory ability of Obat pahit potion from Lingga, Riau Archipelago. This study used white rats as an animal modelling, and Staphylococcus aureus as bacteria tester. The rats had been treated with aqueous Obat pahit extract from three TMPs on dose scales of 0.09, 0.18 and 0.27 mL/200g of body weight through oral administration for 7 days. Furthermore, on the 8th days, the experiment animals were injected by the preparation of bacteria tester through intraperitoneal administration in the amount of 0.5 mL/200 gram of body weigth and subsequently incubated for 1 hour after the injection. There were 2 observed parameters on this study, i.e efectivity and capacity of phagocytosis by leukocytes. The observation of leukocytes-phagocytocis activity was carried out by making a smear preparat samples of peritoneum fluid from rats. After the observation under microscope on a magnification of 100 times. The result was obtained the Obat pahit from Kalan PMT swere more effective on dose 2, while from SP4 and Linau TMPs were much more effective on dose 1. It is therefore, using these data of the results, the advanced doses scale of this Obat pahit would not be necessary. Obat pahit potion from Malay Lingga Malay Ethnic could become raw materials of immunomodulatory herbal medicine based on traditional knowledge. It also potentially as a standardized herbal.

Abstract

The use of synthetic preservatives is not safe for consumption and very dangerous for health.Lactic acid bacteria (LAB) is a probiotic bacterium that can produce bacteriocins asbiopreservatives agents. Bacteriocins have been widely applied as a food preservative, but itscommercial availability is still low and very expensive. This study was conducted to test the abilityof 23 isolates of local probiotic bacteria in Riau to produce bacteriocins. LAB total population wascalculated by Total Plate Count (TPC) method. LAB inhibition test against indicator bacteriaStaphylococcus aureus FNCC 0047 was conducted using well diffusion method. Bacteriocinsantimicrobial confirmatory test was performed at 100OC for 15 minutes, 30 minutes, and 60minutes. The result showed that the highest LAB population was PSG4 (22.45 x 106 cfu/ml) andthe lowest was SLK2 (4.75 x 106 cfu/ml). The greatest inhibitory activity against indicator bacteriaS. aureus FNCC 0047 was found in PSG2 (15.1 mm) and the smallest was in SLK2 (10.75 mm)with the activity of bacteriocins 2575 mm2/ml and 792.6 mm2/ml respectively. The bacteriocinsconfirmatory test showed clear zone of isolates JN5, PSG2, and SLK2 with the largest inhibitionzone was during heating for 30 minutes and 60 minutes (19.2 mm, 19.5 mm, and 16.8 mm) whilethe smallest was for 60 minutes and 15 minutes (12.8 mm, 15.6mm, and 14.7 mm).Keywords: Probiotic bacteria, biopreservatives, bacteriocins, Staphylococcus aureus FNCC 0047.
