Chemical constituents from leaves of Avicennia lanata non ridley, Phamhoang (Avicenniaceae)
Abstract
Avicennia lanata non Ridley, Phamhoang, Avicenniaceae widely grows in mangrove forests. There were some studies on plants of mangrove forests, and these results showed that they contained many interesting bioactive compounds. Nevertheless, Avicennia lanata has not yet been chemically and biologically studied in Viet Nam. From the hexane extract of the leaves of Avicennia lanata, ursolic acid (1), lupeol (2), betulin (3), sitosterol (4), sitosterol 3–O–β–D–glucopyranoside (5), and tectochrysin (6) were isolated. Their structures were identified by comparing their NMR data as well as physical properties with those in literatures. Further studies on this plant are in progress.
