Effects of gamma-terpinene on lipid concentrations in serum using Triton WR1339-treated rats.

We studied lipid metabolism to evaluate the effects of gamma-terpinene on suppression of increases in serum lipid concentrations using Triton WR1339-treated rats. At 6 hr after Triton WR1339 injection, the total cholesterol and triglyceride concentrations in the gamma-terpinene group underwent statistically significant decreases (18.3 and 30.

Characteristic rat tissue accumulation of nobiletin, a chemopreventive polymethoxyflavonoid, in comparison with luteolin.

Nobiletin (NOB), a polymethoxyflavonoid, is an effective anti-inflammatory and chemopreventive phytochemical found in citrus fruits. We compared the absorption and metabolism characteristics of NOB with those of luteolin (LT) in male SD rats. Each flavonoid (67.

Antioxidative effect of citrus essential oil components on human low-density lipoprotein in vitro.

We studied the antioxidative action to evaluate the effect of citrus essential oil components on human LDL in vitro. Among the authentic volatile compounds tested, gamma-terpinene showed the strongest antioxidative effect, and inhibited both the Cu(2+)-induced and AAPH-induced oxidation of LDL. gamma-Terpinene added after 30 min (mid-lag phase) and 60 min (propagation phase) of incubation of LDL with Cu(2+) inhibited LDL oxidation.

Rapid and convenient method for preparing aurapten-enriched product from hassaku peel oil: implications for cancer-preventive food additives.

Aurapten (7-geranyloxycoumarin) has been reported to be an effective inhibitor of chemical carcinogenesis in some rodent models. In the present study, a method for preparing an aurapten-enriched agricultural product has been established. Out of 17 Rutaceae varieties, the aurapten content in hassaku (Citrus hassaku Hort ex Y.
