Where does Dihydroquercetin come from?

DHQ with high-order crystal structure and all the attributes of a Nano system, is a natural bioflavonoid extracted from Siberian larch wood.

Dihydroquercetin was discovered as a part of phenolic complexes derived from many plants. Evergreen trees, especially those from the family of Pinaceae are considered rich sources of dihydroquercetin. Larchwood saw logs become the main source for Dihydroquercetin (DHQ) extraction.  On the role of DHQ in high plants the attention was paid quite long time ago due its properties to extend durability of trees where DHQ was found.  Dihydroquercetin is a molecule mainly found in species of the genus Larix, Douglas Fir, Cedrus and Pseudotsuga. 

Dihydroquercetin is described as an antifungal agent.  Yet, dihydroquercetin is mainly responsible for the high durability of the species mentioned above. Moreover, DHQ inhibited the hormone oxidase degrading activity, thus acting as plant growth regulator facility.
