Abstract:
Further investigation on the alcohol extract of the barks of Taxus yunnanensis led to the isolation of four taxoids, namely, 7beta-xylosyl-taxol D, taxuyunnanines P, Q and R, along with the known taxuyuntin G (2). Four are rearranged taxoids with an 11(15-->1)-abeotaxoid skeleton and an opened oxetane ring moiety. Structures were determined by spectroscopic and chemical means.
