Chemical Constituents of Pinellia ternata(Thunb.)Breit
OBJECTIVE To study the chemical constituents of Pinellia ternata(Thunb).Breit..METHODS The 60% etha-nol extract of Pinellia ternata(Thunb).Breit.was isolated and purified by silica,MCI,ODS andpreparative HPLC,and the struc-tures of obtained compounds were identified by physico-chemical properties and MS、NMR data.RESULTS The compound are kaempferol-3-O-β-D-rutinoside(1),inosine(2),lactariolide I(3),(2E,4E,1'S,2'R,4'S,6'R)-dihydrophaseic acid(4),tryptophan(5),1-oleoyl-3-O-β-D-galactopyranosyl-sn-glycerol(6),6'-O-linoleylsucrose(7),6'-O-palmitoylsucrose(8),gingerglycolipid C(9),(2S)-1-O-6'-O-(α-D-galactopyranosyl)-β-D-galactopyranosyl-3-O-palmitoyl glyceride(10),1-O-hexadecanoyl-3-O-β-D-galato-pyranosylglycerol(11),tianshic acid(12),4-(2-hydroxyethyl)phenol(13),phenylpropionic acid(14),3-phenyllactic acid(15),trans-cinnamic acid(16).CONCLUSION Compound 1,2,3,4,6-13,15-16 are firstly isolated from the genus Pinellia.
