  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.

  摘要：

  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.
