[4] It can be found in conifers like the Siberian larch, Larix sibirica, in Russia, in Pinus roxburghii,[5] in Cedrus deodara[5] and in the Chinese yew, Taxus chinensis var.

[15] The capacity of taxifolin to stimulate fibril formation and promote stabilization of fibrillar forms of collagen can be used in medicine.

[16] Also taxifolin inhibited the cellular melanogenesis as effectively as arbutin, one of the most widely used hypopigmenting agents in cosmetics.

Taxifolin also enhances the efficacy of conventional antibiotics such as levofloxacin and ceftazidime in vitro, which have potential for combinatory therapy of patients infected with methicillin-resistant Staphylococcus aureus (MRSA).

[17] Like other flavonoids, taxifolin is able to function as an antifungal agent by blocking multiple pathways that promote the growth and proliferation of fungi.

Taxifolin prevents hyperlipidemia by reducing the esterification of cellular cholesterol, phospholipid, and triacylglycerol synthesis.

[15] Taxifolin, as well as many other flavonoids, has been found to act as a non-selective antagonist of the opioid receptors, albeit with somewhat weak affinity.

[23] (-)-2,3-trans-Dihydroquercetin-3'-O-β-D-glucopyranoside, a taxifolin glucoside has been extracted from the inner bark of Pinus densiflora and can act as an oviposition stimulant in the cerambycid beetle Monochamus alternatus.
