Improving enzymatic hydrolysis of acid-pretreated bamboo residues using amphiphilic surfactant derived from dehydroabietic acid.

Bioresource Technology, 2019
In this work, amphiphilic surfactant was obtained using dehydroabietic acid from pine rosin and then pre-adsorbed with acid-pretreated bamboo residues (AP-BR) to block the residual lignin adsorption site, which is expected to improve its enzymatic ...

Modeling of the Reaction of Ozone with Dehydroabietic Acid

Ozone: Science & Engineering, 2005
The oxidation of dehydroabietic acid (DHA) by ozone in solution was examined using a spectrophotometric method in combination with the computer program MATLAB to empirically fit the data. The reaction rate constant between the two compounds was determined to be 1.1×102 L/mol·s at 23 oC.

METHYL MIGRATION IN DEHYDROABIETIC ACID DERIVATIVE

Chemistry Letters, 1972
Abstract Benzonilidene compound (2) underwent rearrangement to 3 with 1,2-methyl migration and vice versa. Using the rearrangement, selective substitution at C-l of dehydroabietic acid derivative was accomplished to give 5.

Skeletal Rearrangement of the Dehydroabietic Acid Derivative

Bulletin of the Chemical Society of Japan, 1995
Abstract Methyl 7-oxo-5,8,11,13-abietatetraen-18-oate was reduced with sodium borohydride in the presence of cerium(III) chloride heptahydrate to give the corresponding 7-hydroxy compound, which was rearranged into methyl 7-isopropyl-1,10-dimethyl-1,2,3,4-tetrahydroanthracene-1-carboxylate (14) possessing a rearranged linear abietane ...

Excitatory Actions of Dehydroabietic Acid on Mammalian Synaptosomes

Pharmacology & Toxicology, 1994
Abstract: The presynaptic effects of dehydroabietic acid were investigated using mouse brain synaptosomes as the in vitro model. At concentrations ranging from 10 to 100 μM, dehydroabietic acid depolarises the synaptosomal membrane and causes pronounced release of the neurotransmitters γ‐aminobutyric acid, acetylcholine and L‐glutamate. The effects on
