Ethnopharmacological relevance: Aquilaria spp. Agarwood has also been used as a traditional medicine in Southeast Asian countries, Bangladesh and Tibet. Its common uses include the treatment of joint pain, inflammatory-related ailments, and diarrhoea, as well as a stimulant, sedative and cardioprotective agent. In this paper, we aim to provide an overview of the phytochemistry, ethnomedicinal use, pharmacological activities and safety of plant materials from Aquilaria spp. Materials and methods: Literature abstracts and full text articles from journals, books, reports and electronic searches Google Scholar, Elsevier, PubMed, Read Cube, Scopus, Springer, and Web of Science , as well as from other relevant websites, are surveyed, analysed and included in this review. Results: A literature survey of agarwood plant materials showed that they contain sesquiterpenes, 2 phenylethyl -4H-chromenone derivatives, genkwanins, mangiferins, iriflophenones, cucurbitacins, terpenoids and phenolic acids.

One of the most precious plants on earth is genus Aquilaria which able to produce agarwood. Under this genus, there are more 15 species around the world where the population is dense in Asia region. Four main Aquilaria spp will be discussed; 1 Aquilaria Sinensis , 2 Aquilaria Malaccensis , 3 Aquilaria Crassna and 4 Aquilaria Subintegra which currently being researched for health applications. The review helped researcher to have the brief ideas on the pharmacological effects of agarwood. Request Permissions. Antihyperglycemic activity of agarwood leaf extracts in STZ-induced diabetic rats and glucose uptake enhancement activity in rat adipocytes.
Richter and M. Nomenclature etc. Important species: Aquilaria crassna Pierre ex Lecomte. Description based on 4 specimens. Heartwood basically yellow. Sapwood colour similar to heartwood colour. Density 0.
