概要	Three new clerodane diterpene glycosides, tinosposinensides A-C (1-3), and a new rearranged cadinane sesquiterpene glycoside, tinosinenside (4), were isolated from the stems of T. sinensis. The structure including the relative configuration was elucidated on the basis of spectroscopic anal. The abs. configuration was detd. by application of the modified Mosher's method and chem. transformation. The inhibitory activities of the isolated compds. against .alpha.-glucosidase are also described.
