Abstract:
The aim of this study was the screening of phytochemicals and determination of total hydroxicinamic acids, total polyphenols and antioxidant activity of hydroalcoholic extract ofLavandula angustifolia Mill. cultivated in Craiova - Romania. Phytochemical screening showed that all of samples are positively. Quantitative determination of hydroxycinnamic acids was calculated as chlorogenic acid equivalent in % of dried plant raw material. The total polyphenol content was measured using the Folin Ciocalteu reagent colorimetric method. Antioxidant activity was determined using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenger methods. It has established that in sample ofLavandula angustifoliathe total content of hydroxycinnamic acid derivates is 2.65%, total polyphenols 1.4 mg GAE g-1 DW. The hydroalcoholic extract displayed DPPH free radical scavenging activity with 85.7%.
