Isolation of four new phytoconstituents from the roots of Albizzia lebbeck Benth

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' αhydroxy 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.
