Analysis and Evaluation on Chemical Composition of the Larch Bark
In this paper, Chinese larch bark and different areas of Korean larch bark chemical composition and quantitative analysis of active ingredients, and with several plant resources in the total flavonoids were compared and evaluated. The results showed that: Korean larch bark of ash content (1.34%) lower, phenethyl alcohol extract (16.17%), proanthocyanidins (3.84%), total flavonoids(16.59%) and dihydro-quercetin (4.87% ) the highest. The total flavonoid content is more higher than the development of herbal extracts of total flavonoids. Therefore, the bark is a great potential for development of renewable resources.
