Abstract
In this study, an efficient approach to preparation of different anthocyanins from Purple-heart Radish was developed by combining microwave-assisted extraction (MAE), macroporous resin purification (MRP) and ultrasound-assisted acid hydrolysis (UAAH) for evaluation of physicochemical stability and pancreatic lipase (PL) inhibitory activity. By optimization of MAE, MRP and UAAH processes, the anthocyanins reached the yield of 6.081 ± 0.106 mg/g, the purity of 78.54 ± 0.62 % (w/w) and the content of 76.29 ± 1.31 % (w/w), respectively. With high-resolution UHPLC-Q-Orbitrap/MS, 15 anthocyanins were identified as pelargonins with diverse glucosides and confirmed by pelargonidin standard. By glycosylation, pelargonins exhibited higher stability in different pH, temperature, light, metal ions environments than that of pelargonidin. However, PL inhibitory assay, kinetic analysis and molecular docking demonstrated that pelargonidin had higher PL inhibitory activity than pelargonins even though with similar binding sites and a dose-effect relationship. The above results revealed that the effect of glycosylation and deglycosylation on PL inhibitory activity and physicochemical stability.

Microwave assisted extraction of phenolic compounds from four economic brown macroalgae species and evaluation of their antioxidant activities and inhibitory effects on α-amylase, α-glucosidase, pancreatic lipase and tyrosinase.

Abstract
Four economically important brown algae species (Ascophyllum nodosum, Laminaria japonica, Lessonia trabeculate and Lessonia nigrecens) were investigated for phenolic compound extraction and evaluated for their antioxidant, anti-hyperglycemic, and pancreatic lipase and tyrosinase inhibition activities. Microwave assisted extraction (MAE) at 110 °C for 15 min resulted in both higher crude yield and higher total phenolic content (TPC) for all algae species compared with those obtained by conventional extraction at room temperature for 4 h, and Ascophyllum nodosum yielded the highest TPC. Antioxidant tests indicated that extracts acquired by MAE from four species all exhibited higher DPPH, ABTS free radical scavenging ability and reducing power than the conventional method. The extract of Lessonia trabeculate exhibited good α-amylase, α-glucosidase, pancreatic lipase, and tyrosinase inhibition activities, and the MAE extract showed even better α-glucosidase inhibitory activity than acarbose.
