A new flavanone glycoside, (2S)-dihydrooroxylin A 7-O-[β-D-apiosyl(1→2)]-β-D-glucoside (1), and four known compounds (2-5) were isolated from Tournefortia sibirica L. The chemical structures of these compounds were determined by 1 D and 2 D NMR
BACKGROUND
Tournefortia sarmentosa Lam. (Boraginaceae), a Chinese herbal medicine, is commonly used as a detoxicant or anti-inflammatory agent.
OBJECTIVE
As acetaminophen (APAP) is a well-known hepatotoxin, we investigated the effect of the aqueous extract of the T. sarmentosa on APAP-induced
Three polyisoprenoid alcohols were isolated from the leaves of Tournefortia hirsutissima by a bioassay-guided phytochemical investigation. The compounds were identified as 16-hydroxy-lycopersene (Compound 1), (Z8,E3,ω)-dodecaprenol (Compound 2) and
