Heliciopsis lobata is a medicinal plant, which is exclusively used to treat tumor in Li folk region. Two new arbutin derivatives, 6'-((E)2-methoxy-5-hydroxycinnamoyl) arbutin(1) and 2'-((E)2, 5-dihydroxycinnamoyl) arbutin(2) along with five known compounds(3–7), were isolated from the leaves of Heliciopsis lobata. Their structures were elucidated on the basis of extensive spectroscopic interpretations. They were evaluated for their potential anticancer activity. Compounds 6 and 7 exhibited cytotoxicity against MGC-803 cells with IC_(50) values being 44.1 and 11.3 μg·m L^(–1), respectively. Additionally, compounds 1, 2 and 5–7 exhibited a moderate inhibition of MGC-803 cells invasion; compound 2 at 20 μg·m L^(–1) inhibited the invasion of MGC-803 cells by 43.0%, compared with the controls.. 展开更多
