摘要
The phytochemical investigation of the bark of Tectona grandis Linn. afforded a new steroidal glycoside identified as -sitosterol--D-[4'-linolenyl-6'-(tridecan-4'''-one-1'''-oxy)] glucuranopyranoside and three new fatty esters, 7'-hydroxy-n-octacosanoyl n-decanoate, 20'-hydroxy eicosanyl linolenate and 18'-hydroxy n-hexacosanyl n-decanoate, along with the known compounds n-docosane, lup-20(29)-en-3-ol, betulinic acid and stigmast-5-en-3-O--D-glucopyranoside. Their stereostructures have been elucidated on the basis of spectral data analyses and chemical reactions.
