This study isolated nine compounds from Chinese eaglewood, including novel norditerpenoids. These findings expand the known chemical constituents of this valuable plant resource.

Area of Science:

  • Natural Product Chemistry
  • Phytochemistry
  • Organic Chemistry

Context:

  • Chinese eaglewood (Aquilaria sinensis) is a valuable plant resource known for its aromatic resin.
  • The chemical composition of eaglewood extracts is complex and requires advanced separation techniques.
  • Previous research has identified various compounds, but a comprehensive analysis of specific extracts is ongoing.

Purpose:

  • To isolate and identify chemical constituents from the petroleum ether and ethanol extracts of Chinese eaglewood.
  • To characterize novel compounds and expand the understanding of eaglewood's phytochemical profile.

Summary:

  • Nine compounds were successfully isolated and purified using column chromatography (silica gel, Sephadex LH-20) and semi-preparative HPLC.
  • The identified compounds include dehydroabietic acid derivatives, pimaric acid, pimarol, and three novel norditerpenoids (compounds 5, 8, and 9).
