Influence of harvest stage on the pharmacological effect of Angelica dahurica
Abstract Background Baizhi (Angelica dahurica) has been widely used as a traditional Chinese herbal medicine, functional food and cosmetic product ingredient, mostly because of the high furanocoumarin compounds in roots. The cropping system of Baizhi with its unique summer dormancy feature, is easil...

The aim of this study was to analyze the quantity (size, form and dry weight [DW]) and quality (antioxidant and furanocoumarin content) of taproot and lateral root from three growth stages of Baizhi; vegetative (V-stage), summer dormancy (S-stage) and bolting stage (B-stage).

Although the antioxidant activity was less at S-stage than the other stages, furanocoumarin contents showed little variation. Conclusion Considering the high DW and stable furanocoumarin composition, S-stage is the best harvest stage than the other stages because of its richer total pharmacological content.http://link.springer.com/article/10.1186/s40529-018-0230-1Angelica dahuricaSummer dormancyHarvest timeFuranocoumarinAntioxidant |
