| Cedrol Usage And Synthesis |
| Description | Cedrol is a sesquiterpene alcohol found in conifers mainly of the genera Cupressus, Juniperus, and Cedrus. It has been found to possess significant anticancer activity against glioblastoma in vitro and in vivo via cell growth inhibition, ROS generation, and DNA damage.1 Cedrol also displayed synergistic effects with temozolomide against glioblastoma in vitro and in vivo via reduced expression of drug resistance proteins.1,2 Cedrol inhibited the growth of human renal adenocarcinoma and amelanotic melanoma cells3 and induced autophagy and apoptosis in A549 non-small cell lung carcinoma cells4. | | Chemical Properties | Colorless crystals; cedarwood odor. soluble in 11 parts of 95% alcohol. Combustible. | | Occurrence | Found in the wood of several conifers, particularly cypresses and cedars, including Cedrus atlantica, Cupressus sempervirens, Juniperus virginiana (Fenarolfs Handbook of Flavor Ingredients, 1971). | | Uses | acaricide, enhances skin ECM production | | Uses | In fragrances. | | Uses | (+)-Cedrol can be used as a starting material for the preparation of cedryl acetate by acetylation using acetic anhydride in the presence of an acid catalyst. It can also be incorporated as a precursor for the total synthesis of rare illicium sesquiterpene (+)-pseudoanisatin via selective C-H bond functionalization. | | Preparation | From cedarwood by fractional distillation followed by recrystallization from suitable solvents of appropriate solid fractions. | | Definition | A tertiary terpene alcohol. | | General Description | (+)-Cedrol is a crystalline hydrated product of α-cedrene, which is a sesquiterpene found in cedar-wood oil. It can be used as a fragrance ingredient in cosmetics, shampoos, and soaps as well as in non-cosmetic products such as cleaners and detergents. (±) Cedrol can be synthesized by intramolecular Diels-Alder reaction of alkyl cyclopentadiene. | | Purification Methods | Purify cedrol by recrystallisation from aqueous MeOH. It is estimated colorimetrically with H3PO4 in EtOH followed by vanillin and HCl [Hayward & Seymour Anal Chem 20 572 1948]. The 3,5-dinitrobenzoyl derivative has m 92-93o.
