... 1,8-Cineole (1,8-CIN) is a monoterpene found in diverse dietary and medicinal herbs that has been reported to be effective against cardiovascular diseases.The present research was designed to elucidate the treatment effects and the underlying mechanism of 1,8-CIN on heart failure (HF).An in vitro cardiac hypertrophy model and an in vivo heart failure (HF) model induced by isoprenaline (ISO) were e ...
... Volatile monoterpenes such as 1,8-cineole inhibit the growth of Brassica campestris seedlings in a dose-dependent manner, and the growth-inhibitory effects are more severe for roots than hypocotyls. The preferential inhibition of root growth may be explained if the compounds inhibit cell proliferation more severely than cell elongation because root growth requires both elongation and proliferation ...

Abstract:
... The aromatic descriptor “green”, reflecting grape unripeness in French red wines, is frequently associated with the levels of 3-alkyl-2-methoxypyrazines, particularly 3-isobutyl-2-methoxypyrazine (IBMP), which has bell pepper nuances. Nevertheless, not all green aromatic expressions in red wines correlate with 3-alkyl-2-methoxypyrazine concentrations. This study considered sensory and chemical app ...

However, parasite resistance to those chemical formulations is an increasing global problem, so new plant-derived compounds are being studied for their potential use against gastrointestinal nematodes. Citrus sinensis and Melaleuca quinquene ...
... Monogenean parasites are important ectoparasites of fish, and are responsible for severe economic impacts in the aquaculture industry. They are usually treated with chemicals, but the chemicals can have harmful side effects in the fish and may pose threats to human health.
