“…This statement was in agreement with Padmashree and research group (2007), reported that the antioxidant activity is due to high percentage of trans-Anethole, which is more than 80 % 18 . In the present study, star anise essential oil extracted at 60°C for 1 day has the highest concentration of trans-Anethole (91.61 %) and antioxidant activity (EC 50 =0.089 mg/ml) while star anise essential oil extracted at 30°C for 1 day has the lowest concentration of trans-Anethole (45.03 %) and antioxidant activity (EC 50 =0.973 mg/ ml).…”

“…The ascorbic acid used as a positive control showed IC 50 value of 8 μg/ml. Antioxidant activities of M. fragrans, M. malabarica and I. verum are previously reported [22][23][24][25][26]. and our results conform to these studies.…”

Spices are extensively used to enhance the taste and flavor of foods and are known to possess several medicinal properties. Myristica fragrans, Parmelia perlata, Illicium verum, Trachyspermum copticum and Myristica malabarica, the commonly used spices in India were assessed for antidiabetic activity in streptozotocin induced diabetic rats. In the in vitro insulin secretion studies on isolated islets of Langerhans, M. fragrans, T. copticum and M. malabarica showed dose dependent insulin secretion. At 1 mg/ml, P. perlata showed significant in vitro alpha-glucosidase inhibitory activity with IC(50) value of 0.14 mg/ml followed by M. malabarica (0.64 mg/ml), I. verum (0.67 mg/ml), M. fragrans (0.85 mg/ml) and T. copticum (0.92 mg/ml). The DPPH free radical scavenging activity of the extracts at a concentration of 1 mg/ml was as M. malabarica (90.45%), M. fragrans (89.89%), I. verum (87.22%), P. perlata (76.70%) and T. copticum (38.14%). P. perlata showed the highest phenolic content (i.e., 118.5 mg gallic acid equivalents/g) followed by M. malabarica (84.13 mg gallic acid equivalents/g). M. malabarica showed the highest flavonoid content (i.e., 38.35 mg quercetin equivalents/g). Regular use of these spices may prevent postprandial rise in glucose levels through inhibition of intestinal alpha-glucosidase and may maintain blood glucose level through insulin secretagogue action.

“…However, the inhibition percents of BHA, BHT and PG were much more effective at lower concentrations and were (72.1%), (69.4%) and (71.6%) at 5 mg/mL, respectively. The various solvent fractions of I. verum, along with the spice powder, were evaluated for antioxygenic activity by refined sunflower oil, linoleic acid peroxidaton, ␤-carotene-linoleate and DPPH methods (Padmashree et al, 2007). The inhibition percents of star-anise powder, its petroleum ether, ethanol/water and water extracts were 53.0%, 40.6%, 76.3% and 56.7%, respectively.…”
