Geraniol

Geraniol is a terpene alcohol found in a variety of plants, including Cannabis, that has diverse biological activities, including insecticide, antioxidant, anti-inflammatory, anticancer, and antimicrobial properties.^1,2 Geraniol is an insecticide that induces 100% mortality of C. maculatus, when used at a concentration of 16 µl in an alimentary substrate.³ It has an LD₅₀ value of 0.714 µl in C. maculatus but does not produce adverse effects in rats when administered in the diet at 10,000 ppm for 16 weeks.^3,2 Topical administration of geraniol (250 µg) prevents lipid peroxidation, increases glutathione (GSH) levels, and increases the activity of antioxidant enzymes, including catalase, glutathione reductase, glucose-6-phosphate dehydrogenase, and superoxide dismutase in a mouse skin model of oxidative stress and inflammation induced by phorbol 12-myristate 13-acetate (TPA; Item No. 10008014).⁴ It also decreases the levels of TNF-α, IL-6, and IL-1β in the same model. Geraniol (100 mg/kg) inhibits HMG-CoA reductase and reduces lipogenesis in hamsters fed an atherogenic diet as a model of hyperlipidemia when administered at a dose of 100 mg/kg.⁵ It also induces apoptosis in and decreases viability of COLO 205 cancer cells (IC₅₀ = 20 µM).⁶ Formulations containing geraniol have been used as fragrance ingredients and as insecticides in agriculture.
