Genome of Tripterygium wilfordii and identification of cytochrome P450 involved in triptolide biosynthesis

Nature Communications, 2020
Tripterygium wilfordii is a medical plant that can produce antitumor activity compound triptolide. Here, the authors assemble its genome and identify a cytochrome P450 that can catalyze oxidation of a methyl to the acid moiety of dehydroabietic acid in ...

Photolysis of Abietic Acid to Dehydroabietic Acid and Hydrogen

Spectroscopy Letters, 1994
Abstract Abietic acid, which is the terpene acid component of natural colophony, was irradiated at above 300 nm in the presence of benzophenone and a colloidal platinum catalyst. The expected product of dehydroabietic acid was formed to the extent of 81 %, hydrogen generation occurred to a negligibly small amount.

Distribution of Dehydroabietic Acid in Sediments Adjacent to a Kraft Pulp and Paper Mill [PDF]

, 1977
Sediments adjacent to a kraft pulp and paper mill on western Nipigon Bay, Lake Superior, were examined for resin acids. Dehydroabietic acid was the predominant resin acid with surficial concentrations of less than 5–100 μg/g.The areal distribution ...

One-step Synthesis of Biomass-Based Carbon Dots for Detection of Metal Ions and Cell Imaging

Frontiers in Energy Research, 2022
Biomass-based carbon dots (Bio-CDs) were prepared from dehydroabietic acid using a one-step hydrothermal process. Characterization by TEM, XPS and FTIR spectroscopy showed that the Bio-CDs are spherical nanoparticles containing mainly C, N and O elements,
