A new 5H-purin-6-amine from the leaves of Sedum sarmentosum

초록

Phytochemical constituents were isolated from Sedum sarmentosum leaves using open column chromatography and medium-pressure liquid chromatography. Their structures were identified as 2,4-pyrimidinedione (1), N-methylhydroxylamine(2) ,5H-purin-6-amine (3) , uridine (4) , L-tyrosine (5) , and L-prolyl- L-tyrosine (6) using mass spectrometry and H-1- and C-13-nuclear magnetic resonance spectroscopic analysis. Among them, compound 3 (5H-purin-6-amine) was isolated for the first time from a natural source.
