(7) The method has been applied to 2 benzoin preparations and the results were compared with those from the British Pharmacopoeia method.
(8) This ability is due to benzaldehyde lyase, a new type of enzyme that irreversibly cleaves the acyloin linkage of benzoin, producing two molecules of benzaldehyde.

(10) One such scheme utilizes a selective reaction of benzoin with the guanidine moiety to derivatize arginine residues occurring in a peptide.
(11) It was therefore concluded that caprolactam and benzoin are not clastogenic in the mouse micronucleus test.
(12) The presence of hydrophobic solvent in the reaction medium provides more favourable conditions for benzoin condensation proceeding.
(13) Two methods of podophyllin application, namely hospital-application (regimen A) and self-application (regimen B) of 25% podophyllin in tincture of benzoin compound for the treatment of penile condylomata were compared.
(14) The percutaneous absorption of the fragrances benzyl acetate and five other benzyl derivatives (benzyl alcohol, benzyl benzoate, benzamide, benzoin and benzophenone) was determined in vivo in monkeys.
(15) Benzoin and caprolactam were examined for their capability of inducing alkaline DNA fragmentation in mouse and rat liver DNA after treatment in vivo.
(16) The benzoin reaction, described by Guillain, Laroche and Lechelle (1920) was probably the first test evaluating local (intrathecal) immunity in inflammatory diseases of the nervous system.

(19) The peptides are automatically converted into fluorescent derivatives with benzoin, a fluorogenic reagent for guanidino compounds, after separation on a reversed-phase column (TSKgel ODS-120T) and detection in an ultraviolet absorption detector.
(20) Both non-carcinogenic compounds, benzoin and caprolactam, exhibited no activity.
Styrax
Definition:
(n.) A genus of shrubs and trees, mostly American or Asiatic, abounding in resinous and aromatic substances. Styrax officinalis yields storax, and S. Benzoin yields benzoin.
(n.) Same as Storax.
Example Sentences:
(1) The methodology in use is illustrated by the isolation of cinnamic acid, cinnamyl cinnamate and cinnamyl ricinoleate as the active constituents of the classic medicinal plant product, Styrax asiatica.
(2) Mysterious, enclosed by twisting trunks: rhododendrons, azaleas, magnolias, but viewing points take you above the cloud of maple, acer, styrax, oak leaves to reveal its rainbow vastness fringed by sea and coast: magical.
(3) Following intravenous administration of ergometrin (1 and 10 mg), bunitrolol (1-16 mg) and Utrorale (0.1-4 ml) including its compounds oleum sabinae, oleum terebinthinae, balsamum copaivale and Styrax no uterokinetic activity was recorded at any time.
