Phytochemical studies on meliaceous plants. VII. The structures of two new ionone glucosides from Melia toosendan Sieb. et Zucc. and a novel type of selective biooxidation by a kind of protease

Two new ionone glucosides, melia-ionosides A and B, were isolated from leaves of Melia toosendan Sieb. et Zucc. (Meliaceae) and their structures were elucidated based on combinations of chemical, spectral, and X-ray analytical studies. In addition, a novel type of selective bio-oxidation by a kind of protease (Molsin) was found during the course of the structural elucidation.
