纯度：参考随货COA；温度：< -15 °C；分子式：C35H52O4 × C12H23N；分子量：718.12；说明：primary级别，随货COA一般含 HPLC NMR MS UV IR 等图谱Special Notes：The counterion is determined quantitatively and treated as an impurity in the calculation of the absolute purity. The assigned absolute purity on the certificate of analysis therefore refers to the pure hyperforin. This reference substance contains hyperforin and adhyperforin in the naturally occuring ration of approx. 80:20. The absolute purity for both compounds is given on the certificate of analysis. This reference substance therefore enables the simultaneous determination of hyperforin, adhyperforin and total hyperforins.；
