Two new limonoids from the leaves of Sandoricum koetjape.

Two new andirobin-type limonoids, named sandoripin A and sandoripin B, were isolated from the leaves of Sandoricum koetjape collected in Thailand. Their structures were determined by spectroscopic analysis, as well as by comparison with reported data of closely related compounds.

Isoflavones and rotenoids from the leaves of Millettia brandisiana.

A new isoflavone, 4'-gamma,gamma-dimethylallyloxy-5,7,2',5'-tetramethoxyisoflavone, brandisianin A (1), was isolated from the leaves of Millettia brandisiana, along with one synthetically known isoflavone, 7,4'-di-O-prenylgenistein (2) and twelve known compounds. The structures were elucidated on the basis of extensive spectroscopic analysis. Two isolated compounds were tested for anti-inflammatory activity; 12a-hydroxy-alpha-toxicarol (11) showed significant anti-inflammatory activity.
