Terpenoids and Sterols from Ficus ulmifolia (1-10) and Ficus pseudopalma (1-5).
ABSTRACT
The dichloromethane extract of the air-dried leaves of the endemic and endangered Philippine trees, Ficus pseudopalma and Ficus ulmifolia afforded squalene, polyprenol, β-amyrin fatty acid ester, α-amyrin acetate and β-amyrin acetate. F. pseudopalma also yielded lupeol fatty acid ester, lupenone, oleanone, and ursenone, while F. ulmifolia also afforded lutein, lupeol acetate, β-carotene, phytol, α-amyrin fatty acid ester, sitosterol, and stigmasterol. Their structures were identified by NMR spectroscopy.......
