Agarwood based agroforestry: a review

Journal of Non-Timber Forest Products, 2023
Agarwood is a resinous heartwood of various species of Thymelaeaceae primarily Aquilaria and Gyrinops with aromatic, cultural and medicinal uses. Owing to overexploitation in the wild the trees have become endangered, and cultivation has started all over the natural range and even outside under various agroforestry systems. The present review provides

Three sesquiterpenes from agarwood

Phytochemistry, 1991
Abstract Three new sesquiterpenes, (−)-guaia-1(10),11-dien-15-al, (−)-selina-3,11-dien-9-one, and (+)-selina-3,11-dien-9-ol, have been isolated from Aquilaria agollocha (agarwood). Their structures have been established on the bases of detailed spectroscopic analyses and synthesis. The odoriferous properties of these compounds are also described.

The Chemistry of Agarwood Odorants

2022
The phytochemistry of the fragrant infected heartwood of Aquilaria and Gyrinops species, agarwood (oud), is critically reviewed, highlighting the use of this remarkable natural raw material in perfumery. The chemistry of the two main groups of constituents of agarwood (sesquiterpenoids and chromones) is discussed, focusing particularly on the former ...

Sesquiterpenes of agarwood from Gyrinops salicifolia

Fitoterapia, 2016
Six new sesquiterpenoids (1-6) and six known sesquiterpenoids (7-12) were isolated from agarwood originated from Gyrinops salicifolia Ridl. Most of them gave off aromatic odor, and all the compounds were isolated from this genus for the first time. The structures of 1-6 were elucidated by spectroscopic techniques (UV, IR, 1D and 2D NMR) and MS analysis,

New tricyclic prezizaane sesquiterpenoids from agarwood

Fitoterapia, 2019
Ten new tricyclic prezizaane types sesquiterpenoids (1-10) were isolated from ethyl ether extract of agarwood originated from Aquilaria sp. Their structures were unambiguously elucidated on the basis of 1D and 2D NMR spectra as well as by HRESIMS data.

Four new bi-phenylethylchromones from artificial agarwood

Fitoterapia, 2017
Four new bi-phenylethylchromones (1-4) were isolated from the EtOAc extract of artificial agarwood induced by holing method originating from Aquilaria sinensis (Lour.) Gilg. The structures of new compounds were unambiguously elucidated by one- and two-dimensional NMR and HRESIMS measurements, and the absolute configuration was determined by analysis of
