Identification of Secondary Metabolite Compounds and Cytotoxic Activity Test of Papuan Grape (Sararanga Sinuosa Hemsley) Extract using Brine Shrimp Lethality Test (BSLT) Method
Papua has a diversity of flora species, one of which is the Papuan Grape (Sararanga sinuosa Hemsley). It is commonly used by the Depapre community, Jayapura, as a stamina booster. This research aims to identify the secondary metabolite compounds, to test the cytotoxic activity of Papuan Grape (Sararanga sinuosa Hemsley) extract, and to determine the best concentration that inhabits the growth of Artemia salina larvae using the BSLT method. This study was conducted with the extraction stage using the maceration method by making use of 96% ethanol solvent. Subsequently, the concentration series 0, 50, 100, 150, 200, 250, 300 ppm of Papuan Grape (Sararanga sinuosa Hemsley) extract were made to test the cytotoxic activity on the mortality of Artemia salina shrimp larvae. The results showed that Alkaloids, Flavonoids, Saponins, and Tannins were compounded as secondary metabolite. An antioxidant research that had been carried out previously had LC50 of green-white fruit (12,49 ± 0,35 mg/ml), orange-red fruit (17,62 ± 3,49 mg/ml) and red fruit (12,23 ± 0,46 mg/ml). The community process one stalk of it into juice and used or consumed it two times a day. An inappropriate dose of traditional medicine usage can affect the organ system and had adverse effects in the future The result of cytotoxic research obtained the value of LC50 in ethanol extract of Papuan Grape was 140,863 ppm, and concentration of 250 ppm was the best concentration to inhibit the growth of shrimp larvae (Artemia salina L). The conclusion of this study was the ethanol extract of Papuan Grape (Sararanga sinuosa Hemsley) showed the highest cytotoxic activity and potentially become an anti-cancer agent.
