Chemical constituents from the bark of Aquilaria sinensis

Chemistry of Natural Compounds, 2013
Agarwood (Aquilaria sinensis), well known as an incense in Southeast Asia, has been used as a sedative, analgesic, and digestive aid in traditional medicine. Agarwood leaves are consumed as a healthy tea in Thailand and Taiwan. [1]. Previous phytochemical investigation on Chinese eaglewood revealed characteristic sesquiterpenes and chromone derivatives

Characteristic quality analysis for biologically induced agarwood columns in Aquilaria sinensis

Environmental Research, 2023
Current artificial agarwood-inducing techniques yield low quality and quantities of agarwood. On account of unclear agarwood formation mechanism there's still no high-efficiency agarwood inducing method globally spread. In this study, a complete agarwood column was taken out of the live tree trunk at 6 months post-treatment by a novel agarwood-inducing
