“…These changes might be due to swelling of the tick's body. The ethanolic C. longa extract might cause inhibition of the acetylcholinesterase activity as it contained high levels of polyphenols [39]. Consistent with the effects seen in the present study, Chaaban et al [40] observed that C. longa essential oil caused damage to the tick cuticles, midgut, and brain, and produced a fattening of the body of the third-instar Lucilia cuprina (Diptera: Calliphoridae) larvae.…”

Background and Aim: The soft tick Ornithodoros savignyi is distributed throughout Africa, including Egypt. It primarily attacks camels, cattle, donkeys, and cows; and rarely affects humans. This study evaluated the acaricidal efficacy of ethanolic Curcuma longa extract (Turmeric) on the second nymphs of O. savignyi and then investigated the safety of this herb in rabbits. Materials and Methods: The nymphs were immersed in 10, 5, 2.5, 1.25, and 0.625 mg/ml ethanolic C. longa extract. An additional group was immersed in ethanol as a control. On the 1st, 7th, and 15th-day post-treatment, the mortality percentages, LC50 and LC95 were calculated. The ticks exposed to 10 mg/ml ethanol C. longa extract were investigated by scanning electron microscopy (SEM). Three male New Zealand White rabbits were orally administered 2 ml (two doses) of 10 mg/ml ethanolic C. longa extract, and another three rabbits were orally given two doses of 2 ml of absolute ethanol as a negative control. Histopathological examination of the kidney and liver hematology and the kidney and liver function was performed. Chemical analysis of the extract was determined by gas chromatography-mass spectrometry (GC-MS). Results: The LC50 and LC95 were 1.31 and 15.07, 1.07 and 8.56, and 0.81 and 6.97 mg/ml on the 1st, 7th, and 15th day, respectively. SEM revealed that mamillae and spots on the surfaces of the treated ticks were not discriminating except for some clefts on the surfaces. The histological examination, blood profile, and biochemical analyses revealed no significant differences between the treated and untreated rabbits (p>0.05). GC/MS analysis revealed 50 compounds, and curcumene and t umerone were found to be the major constituents of this ethanolic extract. Conclusion: The ethanolic C. longa extract produced a strong acaricidal effect on the second nymph of O. savignyi, and it was safe to use in rabbits.

“…Phenolic compounds contained in foods have an antioxidant effect, and as such, they are expected to have a significant impact on improving memory function compromised by AD; this potential has been suggested by the findings of several studies (Kim et al, 2005;Orhan et al, 2004). AChE and BChE have been performed by Korean research groups, including: comparative analysis of the AChE inhibitory activities of edible plant extracts, including Angelica gigas and Siberian ginger (Jung et al, 2012a;2012b); analysis of the AChE inhibitory effects of green, puer, oolong, and black teas sold in Korea (Jeong et al, 2009); analysis of the AChE inhibitory effects of ginger, turmeric, and garlic (Jung et al, 2012a;2012b). Although these studies analyzed the AChE inhibitory effects of edible plants, most studies have been limited to medicinal plants.…”

The current study compared the physicochemical properties, antioxidant compounds and activities, of unripe and ripe fruits of three cultivars (Seolhyang, Janghee, and Maehyang) of strawberries grown in Korea. As fruits matured, their soluble solids content increased and their organic acid content decreased. Total phenolic content (TPC) and total flavonoid content (TFC) did not differ between Seolhyang and Maehyang fruits, regardless of maturity, whereas unripe Janghee fruits showed higher TPC and TFC than ripe fruits. Total anthocyanin content was higher in ripe fruits than in unripe fruits. For total antioxidant activity, ripe and unripe Seolhyang fruits showed no differences, whereas unripe Janghee fruits showed significantly higher activity than ripe fruits. TPC and TFC were highly correlated, as were DPPH and ABTS radical scavenging activities. Thus, antioxidant contents and total antioxidant activities differed with variety and fruit ripeness at harvest. Unripe fruits show strong potential for use in functional food manufacturing.
