Four new myrsinol diterpenes, euphorprolitherins A-D (1-3.5), were isolated from the ethanolic extract of the root of Euphorbth prolifera, along with a known one. SPr5 (4). The structures were elucidated on the bmis of their spectxoscopic evidences. The smlcture and relative stereochemistrv of 1 were confirmed by X-ray crystallog-raphy

A new capillary electrophoresis (CE) method for the determination of quinolizidine alkaloids in Sophora medicinal plants was developed. A total of seven alkaloid components (cytisine, sophocarpine, matrine, lehmannine, sophoranol, oxymatrine and oxysophocarpine) were separated within 15 min. The running buffer was a 50mMphosphate buffer containing 1%HP-β-CD and 3.3% isopropanol. The linear calibration ranges were 5.50-88.0µgml−1 for cytisine and lehmannine, 5.00-88.0[1]gml−1 for sophocarpine and sophoranol, 5.60-89.6µgml−1 for matrine and oxysophocarpine, and 24.0-384µgml−1 for oxymatrine. The recoveries of the seven alkaloids were 96.0-102.9% with relative standard deviations from 1.50 to 3.00% (n=5). The methodwas successfully applied to different Sophora medicinal plants including Sophora flavescens, Sophora tonkinensis and Sophora alopecuroides.

From the stems of Kadsura heteraclita, new dibenzocyclo-octadiene lignans, ndmed heteroclitins A-E, were isolated together with the known compounds, kadsurin and interiorin. Their structure, were determined by spectroscopic means
