Abstract
The method of extraction of Agarwood is usually dependent on the purpose of the extract. This systematic review aims to look at the number of studies that use different types of solvents in the process of extraction. There are 3 types of solvents commonly used in the extraction of agarwood essential oils namely methanol, ethanol and water. Each solvent produces different extracts in terms of quantity and quality of the final product. However, there is controversy over the use of solvents as it may cause a cytotoxic effect on the user. Another common type of solvent is water. Although water is a cheap solvent and relatively safe, aqueous extracts have more impurities that make isolating the desired compound difficult. After the extraction process, the crude extract was fractionated into the desired compounds and this technique is widely applied, especially in the whole process of extraction of the agarwood. In conclusion, extraction solvents have certain advantages and disadvantages, and this is one of the reasons why this extraction method depends on the purpose of using the final product such as agarwood essential oil.
Highlights
IntroductionAll part from agarwood plants including stem, skin, leaves, flowers, fruits and twigs have been used from ancient times to produce perfume products, medicines, green tea and cosmetics
Agarwood is a highly valuable product obtained from the trunk and root of the Aquilaria and Gyrinops tree species from the family of Thymalaeaceae
All the studies involved in this review used the solvent extraction method to separate the desired natural products from the raw material
Summary
All part from agarwood plants including stem, skin, leaves, flowers, fruits and twigs have been used from ancient times to produce perfume products, medicines, green tea and cosmetics. The Aquilaria leaves have great potential in medicinal purposes. Aquilaria leaves were used to treat toothache, colic, severe headache, rheumatism and pains during pregnancy due to the presence of alkaloid in the extract (Khalil et al, 2013). It possesses laxative effects (Hara et al, 2008; Kakino et al, 2010a; Kakino et al, 2010b), antihyperglycaemic activity (Pranakhon et al, 2011), antioxidant and antibacterial activities (Hendra et al, 2016)
