Optimised extraction of beta-carotene from Spirulina platensis and hypoglycaemic effect in streptozotocin-induced diabetic mice

摘要

BACKGROUND: Spirulina platensis is rich in beta-carotene, which possesses many important biological activities. This study investigated the ultrasound-assisted extraction and purification of beta-carotene from Spirulina platensis by using response surface methodology (RSM), determined its antioxidant capacity in vitro and explored its hypoglycaemic effect in diabetic mice.
