Received Date: 24 October 1994

Four new taxanes were isolated from the roots of Taxus yunnanensis.Among them, two were determined to contain isobutyrate group and propionyloxy group on C-14 respectively, and one was determined as the least oxygenated taxane.The structures were elucidated by spectroscopic means.
