摘要:One New Flavonoid Glycoside,Myricetin 4'-Methyl Ether 3-O-Beta-D-Xylopyranoside (1) And One New Natural Triterpene Glycoside,Grandoside (2) Were Isolated From A Meoh Extract Of The Leaves Of Syzygium Grande,Together With Thirteen Known Compounds (3-15). The Structures Of The New Compounds Were Determined Through A Combination Of Spectroscopic And Chemical Analyses. All Of The Isolated Compounds Were Evaluated For Their Antifungal,Antibacterial,Anti-Leishmania,Dpph Radical-Scavenging And Cytotoxic Activities By Means Of Mtt Assay.
