Description
Summary:BarlerialupulinaLindl. is a popular perennial herbalspecies commonly used by indigenous people in Malaysia as folk medicine due to its wide range of biological effects on human health.Thepresentstudy reports on extraction and assessment of antioxidants fromthe species, with an aim of exploring potential antioxidants source for application in the production of pharmaceuticals,functional foods and other applications. Several methods of extraction were used in the study: microwave assisted extraction (MAE), soxhlet extraction (SE) and ultrasound assisted extraction (UAE) from leaves of B. lupulinaLindl. Eachextraction method assessed phenolic content, total flavonoid content and antioxidant activity. The results have shown no variation between the three extraction methods (P < 0.05).The extracts of samples exhibited more than 80% inhibition scavenging activity against 2,2-diphenyi-1-picrylhydrazyl (DPPH) radical and almost 50% inhibition scavenging activity against Azino-bis-3-Ethylbenzothiazoline-6-Sulfonic Acid (ABTS) radical. The study identified that MAE was more efficient method of extraction forantioxidants from the species under study based onthe short timeframe required. The present paper provides information to existing knowledge on available technologies for the good of mankind.
