Triterpenoids from Pouteria campechiana (H.B.K.) Baehni
The ethyl acetate extract of the stem bark of Pouteria campechiana (H.B.K.) Baehni afforded spinasterol (PC19) and three fatty acid esters of triterpenes: erythrodiol (PC3), betulinic acid (major compound of PC11) and oleanolic acid (minor compound of PC11). The last two were obtained as a mixture (...
