Abstrak: Tanaman ranti hitam (Solanum blumei Nees ex Blume), famili Solanaceae, ditemukan di daerah Karo dan Dairi, secara tradisional digunakan sebagai tanaman obat. Penelitian metabolit sekunder dari ekstrak tanaman S. blumei Nees ex Blume lokal bertujuan untuk mengembangkan potensinya sebagai bahan obat. Hasil analisis fitokimia ekstrak S. blumei Nees ex Blume menunjukkan bahwa metabolit sekunder alkaloid, flavonoid, tannin dan saponin lebih banyak terdapat pada ekstrak etanol daun daripada ekstrak etanol buah. Kuinon hanya terdapat pada ekstrak etanol daun. Fenol banyak terdapat pada eksrak etil asetat daun dan buah.Steroid dan triterpenoid banyak terdapat pada ekstrak n-heksana dan etil asetat daun dan buah serta dalam ekstrak etanol daun. Rendemen ekstrak nheksana, etil asetat dan etanol daun S. blumei Nees ex Blume berturut-turut adalah 1,76 %; 3,17 % dan 9,95% (b/b). Rendemen ekstrak n-heksana, etil asetat dan etanol buah S. blumei Nees ex Blume berturut-turut adalah 1,21%; 2,50% dan 4,09 %(b/b).

Abstract: Ranti hitam plant (Solanum blumei Nees ex Blume), Solanaceae family is found in Karo and Dairi, traditionally used as a medicinal plant. The results of phytochemical analysis of extract of S. blumei Nees ex Blume shows that secondary metabolites alkaloids, flavonoids, tannins and saponin are more numerous in the ethanol extract of the leaves than the ethanol extract of the fruit. Quinone is only found in the ethanol
Two tryptamine-type alkaloids dehydroxyl scorodocarpine, a new compound 1 and scorodocarpine B (2) were isolated from n-hexane extract of the fruits of Scorodocarpus borneensis Becc by chromatographic methods. Their structures were established based on spectroscopic analysis (UV, IR, NMR, MS) and comparison with those related compounds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
