In the present study, five new -kaurane diterpenes including 4α-hydroxy-17,19---kaurane-16-one (), 4-hydroxy-16-H-18---kaurane-17-oic acid (), 4,17-dihydroxy-16α-acetoxy-18-nor--kaurane (), Annosquamosin Z () and 16-H--kaurane-17,18-dioic acid, 17-methy ester () were isolated from L. pericarp. The compounds were also evaluated for their cytotoxic activities against SMMC-7721 and HepG2 cell lines, among which compound exhibited potent cytotoxicity with IC value of less than 20 μM.
