Sažetak

Lavandula angustifolia was used to treat flus and fevers, joint swelling and pain in Uighur medicine. This study aimed to investigate antioxidant, antit anti-inflammatory and antalgic noids content (530.1mg/g rutin/g dry extract) with stronger DPPH scavenging abilities and reduciactivities of total flavonoids from Lavandula angustifolia (LTF). Results indicated that LTF possesses the highest total flavong power. Some flavonoids separated from LTF, and their DPPH scavenging abilities as follows: rosmarinic acid (2, near to Vit C) >luteolin (3) >apigenin (4) >luteolin 7-O-β-D-glucoside (5) >apigenin 7-O-β-D-glucoside (6) >luteolin 7-O-β-D-glucuronide (7). LTF significantly decreased malondialdehyde (MDA) level in D-galactose induced aging model compared to the control group (P<0.05), as well as significantly increased plasma superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities (P<0.05). Moreover, 17.4, 34.8 and 69.6 mg/kg doses of LTF were exhibited significant analgesic and anti-inflammatory activities in a dose dependent manner (P<0.05). Cytotoxicity of LTF on Bel-7402 and Hela cell lines were showed by MTT assay also. These results verified traditional usage of this plant and suggested also that LTF is worth developing and studying further.
