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.

UJI TOKSISITAS DAN SKRINING FITOKIMIA TEPUNG GABAHPELEPAH AREN (Arenga pinnata)ABSTRAKTelah dilakukan penelitian uji toksisitas dan skrining fitokimia tepung pelepah aren. Tepung pelepah aren secara tradisional digunakan oleh masyarakat Tomohon sebagai obat untuk menghilangkan gatal-gatal dan luka bakar pada kulit, namun pemanfaatan ini belum dikenal secara luas di Sulawesi Utara. Pemanfaatan tepung pelepah aren sebagai obat tradisional ini belum banyak dilaporkan dalam literatur bahkan belum ada yang meneliti tentang sifat toksik dan kandungan senyawa metabolit sekunder yang terdapat pada tepung pelepah aren. Tujuan penelitian dalam pengujian toksisitas adalah untuk mengetahui apakah tepung pelepah aren bersifat toksik atau tidak selanjutnya menentukan nilai LC50-nya untuk mengetahui jumlah konsentrasi penyebab ketoksikan tepung pelepah aren. Metode yang digunakan untuk pengujian toksisitas adalah dengan menggunakan larva udang jenis Artemia salina Leach. Dalam metode ini A. salina Leachdipakai sebagai bioindikator. Metode ini mudah dikerjakan, murah, waktu deteksi singkat dan dapat dipertanggungjawabkan. Hasil yang diperoleh dari ekstrak etanol tepung pelepah aren bersifat toksik dengan nilai LC50-nya adalah 6,295 ppm dan hasil pengujian fitokimia menunjukkan bahwa tepung pelepah aren mengandungsenyawa metabolit sekunder yaitu alkaloid yang ditunjukkan dengan pembentukan endapan jingga ketika direaksikan dengan pereaksi dragendorf, triterpenoid yang ditunjukkan dengan perubahan warna jingga pada sampel dan tanin yang ditunjukkan dengan pembentukan endapan putih ketika direaksikan Gelatin.Kata kunci: pelepah aren, skrining fitokimia dan uji toksisitasTOXICITY TEST AND PHYTOCHEMICAL SCREENING ONPALM SUGAR LEAF MIDRIB FLOUR (Arenga pinnata)ABSTRACTA study of toxicity test and phytochemical screening on sugar palm midrib flour had been conducted. The flour is traditionally used as medicine to relieve itching and skin burn, although the use is not widely known in North Sulawesi. Utilization of this flour as a traditional medicine had not been widely reported in the literatures and the toxicity and content of secondary metabolites contained in the sugar palm midrib had not been studied. The purpose of this research was to determine the toxicity of the flour and the value of LC50 in order to find the concentration that causes its toxicity. The research method involved the use of Artemia salina Leach shrimp larvae as a bioindicator. This method was easy to perform, inexpensive, had short detection time, and reliable. The results showed that the ethanol extracted flour was toxic and had LC50 value of 6,295 ppm. The phytochemical screening showed that the flour contained secondary metabolite of alkaloid which was indicated by orange precipitation by using reagent Dragendorf, of triterpenoid which was indicated by orange discoloration, and of tannin which was indicated by white precipitate by using gelatin.Keywords: sugar palm midrib, phytochemical screening and toxicity test

Exploration of the natural product as pharmaceutical drug widely discover continuously for human life. The unique chemical compounds have been explored from bark stem of Melochia Umbellata (Houtt) Stapf var. degrabrata K. (M. umbellata) which is obtained from South Sulawesi, Indonesia. We discovered two group compounds isolated namely stigmasta-5,22-dien-3-β-ol (1) and stigmasta-5,22-dien-on (2), from n-hexane and chloroform extracts. The chemical structure of compounds 1 and 2 were identified based on IR spectroscopic, 1H NMR and 13C NMR and compared spectra data with data of compounds by other researchers. Compounds 1 and 2 are evaluated of their toxicity activity against shrimp larvae (Artemia salina) shows that the compound 1 shows weak toxicity activities against Artemia salina with LC50 value of 548.48 μg/mL, meanwhile the compound 2 exhibits a high inhibitory by LC50 value of 410.81 μg/mL. Based on this study, we suggest that the compound 2 has good bioactivity compared with compound 1.
