Calculate Dilution Ratios(Only for Reference)
* Note: If you are in the process of experiment, it's need to make the dilution ratios of the samples. The dilution data of the sheet for your reference. Normally, it's can get a better solubility within lower of Concentrations.

|Stilbene derivatives from Gnetum cleistostachyum.[Pubmed: 15621615]|
|Three new stilbene derivatives, named gnetucleistol A (1), Gnetucleistol B (2) and C (3), together with four known compounds, gnetifolin A (4), p-hydroxycinnamic acid (5), piceatannol (6) and resveratrol (7), were isolated from Gnetum cleistostachyum C.Y. Cheng (Gnetaceae). Their structures were elucidated on the basis of spectroscopic evidence (EI-MS, UV, IR, NOE, 1H, 13C and 2D NMR).
