title: Resorcinol derivatives from Ardisia maculosa.
abstract: Besides a series of known sterols and triterpenoids, a new resorcinol (1) and a known resorcinol (2) have been isolated from ethanol extract of Ardisia maculosa for the first time. The structures of these resorcinol derivatives were elucidated as 2-methyl-5-(Z-heptadec-8-enyl) resorcinol and 5-Z-heptadec-8-enyl) resorcinol by HRESI-MS, NMR ((1)H, (13)C, HSQC, HMBC) experiments. In our in vitro assay, compounds 1 and 2 showed no antimicrobial activities, however, compound 2 exhibited cytotoxity activity against human cancer cell line with GI(50) value of 2.14 x 10(- 4) mmol/ml.
