One new flavonoid glycoside, myricetin 4′-methyl ether 3-O-β-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. 相似文献
