| Abstract: | Chemical constitution of tannins from domestic barks of Pinus elliottii and Pinus yunnanensis were first studied to be polymeric procyanidins,which are constituted mainly by unitS with 2,3-Cisconfiguration in that of P. elliottil,and of 2,3-trans configuration in that of P.yunnanensis.Molecular weight.Stiasny value and gel time of tannins were also Studied. |
