Triterpenes from Alstonia scholaris(L.) R. Br.flowers
Chemical investigation of the dichloromethane extract of the flowers of Alstonia scholaris(L.) R. Br. afforded mixtures of a-amyrin acetate (1a), β-amyrin acetate (1b) and lupeol acetate (1c); and α-amyrin fatty acid esters (2a), β-amyrin fatty acid esters (2b), lupeol fatty acid esters (2c)and phyt...

| Summary: | Chemical investigation of the dichloromethane extract of the flowers of Alstonia scholaris(L.) R. Br. afforded mixtures of a-amyrin acetate (1a), β-amyrin acetate (1b) and lupeol acetate (1c); and α-amyrin fatty acid esters (2a), β-amyrin fatty acid esters (2b), lupeol fatty acid esters (2c)and phytyl fatty acid esters (2d). The structures of 1a-2d were identified by comparison of their NMR data with literature data. |
