Abstract: Ku-Ding-Cha as a famous traditional drinking tea was used in the south China for a long time. There are a lot of plants which belong to different families and genera were used as its original ma-terials. From the leaves of Ligustrwn purpurascens Y. C. Yang (Oleaceae), a kind of the materials of Ku-Ding-Cha in Yunnan Province, two new phenylpropanoid glycosides, ligupurpuroside A and B were isolated, together with the Z / E isomer mixture of 2- (3, 4-hydroxyphenyl) ethyl (3- 0- α- L-rhamnopyranosyi) ( 4- 0- coumaroyD-0-β-D-glucopyranoside, the mixture of osmanthuside B and its cis isomer, as well as acteoside and three known flavonoid glycosides, luteolin -7-glucoside, cosmosiin and rhoifolin. On the basis of spectroscopic evidence, the structures of the new glycosides were established as 2-(3,4-dihydroxyphenyl) ethyl- [3- 0-α- L-rhamno-pyranosyi (1→ 4)-α-L-rhamnopyranosyl] [ 4-0 -E-caffeoyl] -0-β-D-glucopyranoside and 2-β-hydroxyphenyl) ethyl [3-0 -α-L-rhamnopyranosyl(l →4)-α-L-rhamnopyranosyl) C 4-0-E-p-couOTaroyl) -0 -β-D-glucopyranoside, respectively.
