Chemical constituents of the stems of Ficus triangularis

Chemical constituents of the stems of Ficus triangularis

Chemical investigation of the stems of Ficus triangularis afforded 3,5,4'-trihydroxy-6",6"- dimethylpyrano[2",3":7,6]flavanone (1), a mixture of α-amyrin fatty acid ester (2a), β-amyrin fatty acid ester (2b) and lupeol fatty acid ester (2c) in a 2:1:1 ratio, stigmast-4-en-3-...
