ABSTRACT Angelica keiskei has been well documented as a promising resource rich in bioactive chemicals, especially flavonoids. Field‐assisted extraction and their hybrids have proved to be advanced approaches for the efficient utilization of flavonoids compared conventional methods. The current study aims optimize conditions from A. through high‐pressure processing, ultrasound‐assisted extraction, microwave‐assisted extraction. Furthermore, taking total flavonoid content, phenolic antioxidant activity indexes, three combination methods, processing combined with were further investigated enhance efficiency. results indicate that extracts obtained by optimal content (41.671 mg/g) (12.071 mg/g), strongest activity. Scanning electron microscopy analyses reflect treatment imposed most pronounced damage , which particles changed into smaller size. In vitro experiments demonstrate it can effectively inhibit α‐amylase tyrosinase, suggesting its potential hypoglycemic whitening This demonstrates may serve possible source antioxidants, whereas might represent an innovative advantageous method .

ABSTRACT Natural products play a vital role in human health because people find that they can reduce the incidence of many diseases, such as cancer and cardiovascular diseases. Therefore, researchers have developed effective techniques for screening separating active compounds from natural products. High‐speed countercurrent chromatography is unique unsupported liquid–liquid technology has been widely used separation In this paper, research progress components by combining high‐speed with other technologies reviewed two aspects: pre‐column activity assay post‐column assay. The purpose paper to provide some theoretical support chromatography. I hope contents summarized more basis development realize large‐scale preparation.
