Abstract

Objective: To isolate and identify the chemical constituents from the pulp extract of melon. Method: The constituents were isolated with the combination of silica-gel column chromatography and Sephadex LH-20 column chromatography. The structures were identified on the basis of 1H and 13C-NMR

ESI-MS spectroscopic analysis as well as chemical properties with the comparison of reported compounds. Result: Eight compounds were obtained and identified as 3

5-dimethoxyl-benzyl alcohol-4-O-β-D-glucoside(1)

6-dimethoxyl-4-hydroxyl-phenol-1-O-β-D-glucoside(2)

1-O-p-coumaroylglycerol(3)

coniferin(4)

cucumegastigmanes II(5)

linarionoside C(6)

δ-viniferin(7)

kaempferol-3-O-glu-rha-glu(8). Conclusion: Compounds 1-8 are all isolated from this plant for the first time.
