| Abstract: | From the barks of Taxus yunnanensis, a new paclitaxel-related compound, 7-xylosyl-taxol D (1), and three new 11(15?1)-abeotaxoids, taxuyunnanines P-R (2-4) have been isolated. Their structures were determined on the basis of spectral methods. Taxuyunnanines P-R are a rare type of naturally occurring abeotaxoids with an opened D-ring system. |
