|Format:||Slightly colored ethanolic solution|
|Purity:||>95 % determined by HPLC; <2 % Hyperforin by HPLC|
|Solubility:||Soluble in methanol and ethanol|
|Stability:||Adhyperforin is very unstable, decomposing rapidly in the presence of oxygen and light. It appears to be more stable in ethanol and methanol than as a solid.|
|Storage:||-20C, avoid exposure to oxygen and direct sunlight|
Adhyperforin HPLC Chromatogram.
Purification Notes: Initial silica chromatography separates oils and polar components from hyperforin and adhyperforin. Then C18 chromatography is used to separate hyperforin and adhyperforin. Hyperforin is in greater quantity and in the reversed phase system, hyperforin leads the adhyperforin. This means that the initial fractions will be hyperforin devoid of adhyperforin, and the later fractions will be adhyperforin contaminated with low levels of hyperforin.
