The fruits of Heracleum aquilegifolium Wight (Apiaceae) were collected from Western Ghats of the Indian Peninsula. The essential oils were extracted by hydrodistillation. The chemical composition of the essential oils was analysed by gas chromatography and gas chromatography-mass spectrometry (GC-MS). β -Pinene (22.3%), 1,8-cineole (20.3%), and β-phellandrene (12.4%) were the main components of H. aquilegifolium fruit oils. The antioxidant properties of essential oils of H. aquilegifolium were examined by different procedures namely reducing power ability, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, nitric oxide radical scavenging activity, hydrogen peroxide scavenging activity, hydroxyl radical scavenging activity, superoxide anion scavenging activity, and metal chelating activity. The antioxidant activities were compared with those of synthetic antioxidants and standard drugs such as butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), ascorbic acid, α-tocopherol, curcumin, and quercetin. The study confirmed the possible antioxidant potential of essential oils tested with various in vitro antioxidant methods. The presence of monoterpenes in combination with other components in the oils could be responsible for the activity

AbstractThe aim of the work was to investigate antitumoral effect of essential oils on cancer cells and their possible protective (antioxidant) effects against hydrogen peroxide-induced cytotoxicity. Also, in vitro antioxidant properties of essential oils and aqueous extracts from wild form and cultivated form of Salvia pisidica were compared.We found out that essential oils from wild form (IC50 128, and 85.17 μg /mL) and cultivated form (IC50 115.00 and 74.83 μg/mL) differed in their antitumoral effects on Hep G2 and H1299 cells respectively. As a very important we consider the finding that both essentials oils significantly reduced the cytotoxicity induced by the strong oxidant in cancer cells. We assume that protective effect of essential oils on cancer cells against H2O2 cytotoxicity can be accompanied by their antioxidant action.Antioxidant properties of essential oils and aqueous extract from wild and cultivated S. pisidica were determined by different test systems. In DPPH assay, the weakest radical scavenging activity was exhibited by the aqueous extract from wild form (66.55 ± 1.15 μg/mL). Similarly inhibition of linoleic acid oxidation of aqueous extract from wild and cultivated form (50.93% and 59.66%) was lower than essential oils. In the case of reducing power assay and hydroxyl radical scavenging activity, a similar activity pattern was observed as given in the first two systems. Essential oils from wild and cultivated form had higher reducing power activity (EC50; 100.99 ± 3.0 and 96.87 ± 3.15 μg/mL) and hydroxyl radical scavenging activity (EC50; 15.99 ± 0.95 and 13.01 ± 1.35 μg/mL) than aqueous extracts.
