Taxifolin is a flavanonol, a type of flavonoid. It was firstly isolated from the leaves of a Japanese plant Hinoki cypress1. It is highly efficient anti-oxidant and shows better activity as compared to other antioxidants. Up till now it has been detected in more than fifty plants i.e. in some species of rose2, cactus3, milk thistle4, water pepper5, apple and larch6.
Larch is quite under attention by many researchers. This is a potential source of taxifolin. This plant belongs to china under 5 different species. It possesses many physical properties such as; rigidness, straight grain and corrosion resistance, the wood of these conifers is widely used in furniture fabrication and building construction7.
Researchers conducted a study in order to differentiate the presence of flavonoids in one species of Lark plant with the help of high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). They determined the contents of taxifolin and other flavonoids with this analysis.
With these spectroscopy results all flavonoids contents were separated and peaks were obtained in the form of graphs.
The primary ingredient of the extract was identified as taxifolin with detection of other compounds such as; aromadendrin, eriodictyol, quercetin and kaempferol. The above extract exhibited strong antioxidant activity, exceeding that of butylated hydroxytoluene, a well known synthetic antioxidant, which was primarily attributed to its high flavonoid content. The extract of Larix olgensis var. koreana provides a new resource for taxifolin antioxidant in the food industry.
