Compounds from the stem bark of Schima superba were isolated and purified by a combination of various chromatographic techniques including positive phase silica gel, ODS, Sephadex LH-20 gel, and preparative HPLC methods. Their structures were elucidated by physiochemical property, MS and NMR analysis. Results showed that 9 compounds were obtained from 70% ethanol extract of the stem bark of S. superba and identified as triacontanoic acid(1), hexadecanoic acid(2), dodecanoic acid(3), pinonesinol(4), quercetin(5), kaempferol(6), americanin A(7), quercetin 3-O-β-D-glucopyranoside(8) and quercetin 3-O-α-L-rhamnopyranoside(9). Compounds 1—4 were firstly isolated from S. superba. Compounds 5, 7 and 9 were firstly isolated from the genus Schima.
