What's the difference between borneol and camphol?
Borneol
Definition:
(n.) A rare variety of camphor, C10H17.OH, resembling ordinary camphor, from which it can be produced by reduction. It is said to occur in the camphor tree of Borneo and Sumatra (Dryobalanops camphora), but the natural borneol is rarely found in European or American commerce, being in great request by the Chinese. Called also Borneo camphor, Malay camphor, and camphol.
Example Sentences:
(1) Borneol is an organic drug having property to form eutectic mixture with salicylic acid.
(2) The aromatherapeutical use of commercial valerian root oil (Chinese origin) and of pure fragrance compounds--borneol, isoborneol, bornyl acetate (main constituent of the proved valerian root oil) and isobornyl acetate--as potentially drugs with sedative effects after inhalation was investigated in an animal experiment (mice).
(3) The identity of the major biosynthetic product as borneol was confirmed by chemical oxidation to camphor and crystallization of the derived oxime to constant specific radioactivity.
(4) With the preparation of borneol-beta-cyclodextrin inclusion compound, the stability of the product was improved.
(5) Borneol (I) and isoborneol (II) in synthetic Bingpian are separated by means of dry-column chromatography (DCC).
(6) The results showed that the borneol-salicylic acid eutectic mixture can evidently increase the absorption rate of borneol and provided a method for manufacturing borneol preparation which can easily be absorbed transdermally.
(7) Sage (Salvia officinalis) is shown to contain two electrophoretically distinct dehydrogenases for the respective oxidations of (+)-borneol to (+)-camphor, and of (+)-cis-sabinol to (+)-sabinone en route to (-)-3-isothujone.
(8) Antithrombotic xinmaining were composed with Moschus, Calculus Bovis, Borneol, Radix Ligusticum, Flos Sophorae Immaturus, Radix Salviae Miltiorrhizae, Leech, etc.
(9) As the concept of odorant group plays an important role in the understanding of olfactory coding, an attempt was made to investigate in detail the group properties of a number of structurally and qualitatively related molecules: 1,8 cineole, DL-camphor, borneol, iso-borneol, adamantane, fenchone, fenchyl alcohol, 3,3,5-tri-methyl cyclohexanone, camphene, 1,1,2,2-tetra-bromoethane.
(10) The stereochemistry of the borneol was verified as the (-)-(1S,4S) isomer by oxidation to camphor, conversion to the corresponding ketal with D-(-)-2,3-butanediol, and separation of diastereoisomers by radio-gas-liquid chromatography.
(11) The pathway for the formation of (-)-(1S,4S)-camphor was therefore identical to that previously demonstrated for the (+)-(1R,4R) isomer, involving cyclization of geranyl pyrophosphate to bornyl pyrophosphate, hydrolysis of this intermediate to borneol, and oxidation of the alcohol to the ketone.
(12) Similarly, tansy (Tanacetum vulgare) is shown to contain two electrophoretically distinct dehydrogenases for the respective oxidations of (-)-borneol to (-)-camphor and of (+)-cis-sabinol to (+)-sabinone en route to (+)-3-thujone.
(13) Analysis of the derived benzoates by mass spectrometry demonstrated each of the product borneols to possess an 18O enrichment essentially identical with that of the respective acyclic precursor.
(14) The most optimal concentration of borneol-walnut oil was 20% through clinical and laboratory observations.
(15) Due to its simple composition, significant therapeutic effects and nontoxic reactions, the borneol-walnut oil has been proved a promising external remedy for the treatment of purulent otitis media.
(16) We compared the transdermal absorption rate of borneol alone with that of borneol-salicylic acid eutectic mixture in hairless rats.
(17) In order to enhance the detection sensitivity of various glucuronic acid conjugates (phenol, menthol borneol, estrone and testosterone) in high-performance liquid chromatography (HPLC), the compounds were esterified with 4-bromomethyl-7-methoxycoumarin in the presence of potassium carbonate and 18-crown-6 in acetone.
(18) Camphane was hydroxylated to borneol and epiborneol, the latter predominating.
(19) A soluble enzyme preparation from immature leaves of this plant converts the acyclic precursor [1-3H]geranyl pyrophosphate to the bicyclic monoterpene alcohol borneol in the presence of MgCl2, and oxidizes a portion of the borneol to camphor in the presence of a pyridine nucleotide.
(20) 170 patients were treated with borneol-walnut oil of various concentrations, and the controls (108 patients) were treated with neomycin compound.
