Isolation of four new phytoconstituents from the roots ofAlbizzia lebbeck Benth

[摘要] Phytochemical investigation of the methanolic extract of the roots of Albizzia lebbeck Benth. (Fabaceae) led to the isolation of one new fatty acid ester 2' α- hydroxy octyl hexadecanoate (hydroxyoctyl palmitate) and two new phenolic acid glucosidic ester characterized as salicylic acid-2-O–β-D-glucofuranosyl-6'-octadec-9"-enoate (salicylic acid arabinosyl oleate) along with a fatty acid phytoconstituent, docos-3-en-1-oic acid (docosenoic acid), and two esters tricosanyl hexadecanoate and hexacosanyl octadec-9-en-1-oate (hexacosanyl oleate). The structures of all these phytoconstituents have been elucidated on the basis of spectral data analysis and chemical reactions.
