In general, the hydroxyl group makes alcohols polar. 24034-73-9, formula is C20H34O, Because of hydrogen bonding, alcohols tend to have higher boiling points than comparable hydrocarbons and ethers. Quality Control of 24034-73-9
Xu, Xiujuan;Lu, Ping;Shi, Qingzhao;Chen, Mengqi;Yang, Chunqiang;Qu, Zhan;Cui, Kai;Li, Mingzhe;He, Baojiang;Hu, Shaodong research published 《 Chemical analysis and sensory evaluation of main components in essential oil of cigar tobacco》, the research content is summarized as follows. In order to analyze the chem. components in the essential oil of cigar tobacco and to evaluate their effects, the essential oil of cigar tobacco was prepared by using subcritical extraction and mol. distillation technol. The enrichment effects of various components in the essential oil at different distillation temperatures were clarified. The main chem. components of the essential oil were analyzed by GC/MS, and the influences of mass fractions of various components in the essential oil on the sensory quality of cigarettes were further verified through sensory panel evaluation. The relationships between some aroma components and sensory evaluation indexes were studied via relevant anal. The results showed that at the distillation temperature of 60-80 °C, the mass fractions of nicotine, alkanes and long-chain aliphatic esters were reduced, and the aroma components with cigar styles were effectively enriched. The mass fractions of geranyl acetone, β-ionone, megastigmatrienone, dihydroactinidiolide, farnesyl acetone, phenylacetic acid, acetic acid, propionic acid, dihydro-β-ionone, n-hexanoic acid, 6-methyl-5-heptene-2-one, thujopsene and (E)-nerolidol in the essential oil were significantly pos. or extremely significantly pos. correlated with the quality evaluation indexes of cigarettes, including aroma, comprehensive taste, woody and honeysweet scents. Therefore, these compounds can be used as the main indexes for evaluating the quality of essential oil of cigar tobacco.
24034-73-9, Geranylgeraniol is a diterpenoid that is hexadeca-2,6,10,14-tetraene substituted by methyl groups at positions 3, 7, 11 and 15 and a hydroxy group at position 1. It has a role as a plant metabolite, a volatile oil component and an antileishmanial agent. It is a diterpenoid and a polyprenol.
Geranylgeraniol, a precursor to geranylgeranylpyrophosphate, is an intermediate in the mevalonate pathway. Geranylgeraniol has been shown to prevent bone re-absorption, inhibition of osteoclast formation, and kinase activation in vitro. When working with statins, Geranylgeraniol can reduce the toxicity without inhibiting the cholesterol-producing effects. Geranylgeraniol has been documented to counteract the effects of fluvastatin by inhibiting activation of caspase-1 and production of IL-1. Additionally Geranylgeraniol has been found to induce apoptosis in HL-60 cells.
