Phytochemicals and Biological Activities of Pueraria Flower: A Review

Abstract

Pueraria lobata (Kudzu root) has been well documented as a food and also an herbal plant for its ability to alleviate hangover, diarrhea and cardiovascular diseases. However, the flower of Pueraria lobata has been attracted attention only in recent decades. Bioactive phytochemicals such as isoflavones, saponins, essential oils and other components have been isolated and identified in Pueraria flower extracts (PFE). Both in vivo and in vitro research have indicated the health promoting effects of Pueraria flower including hepatoprotective property, estrogenic effects, antioxidant activity, anti-inflammation activity and other pharmacological activities. In this review, we have summarized the chemical compositions and pharmacological actions of Pueraria flower and updated knowledge with recent progress.
