AI Article Synopsis

  • - Two new derivatives of 2-(2-phenylethyl)chromone were isolated from an ethyl acetate extract of artificial agarwood, marking the first time such compounds have been identified from this genus.
  • - The structures of these compounds were determined using various advanced techniques, including UV, IR, NMR, and HRESIMS analyses.
  • - Bioassay tests indicated that these new compounds exhibited weak inhibitory activity against acetylcholinesterase at a concentration of 50.0 μg/ml.

Article Abstract

Two new 2-(2-phenylethyl)chromone derivatives (-) were isolated from the ethyl acetate extract of artificial agarwood induced by holing method originating from (Lour.) Gilg, and they were isolated from this genus for the first time. The structures of these two new compounds were elucidated by extensive spectroscopic analyses, including UV, IR, one- and two-dimensional NMR and HRESIMS measurements. Bioassay tests of these two new compounds showed compounds and had weak inhibitory activity against acetylcholinesterase at a concentration of 50.0 μg/ml.

Agarwood is a precious resinous heartwood highly valued for its cultural, religious, and medicinal significance. With the increasing market demand, natural agarwood resources are rapidly depleting, making the development of effective artificial induction methods for agarwood highly significant. This study aims to explore the feasibility of using callus tissue to assess the ability of fungi to induce agarwood formation.

Article Synopsis
  • - Agarwood, a valuable resinous wood from Aquilaria and Gyrinops species, is often faked in the market due to its high economic value, raising the need for a reliable authenticity identification method.
  • - The study analyzed the microstructure of authentic agarwood and compared it to counterfeit versions, discovering that real agarwood has a distinct resin-filled phloem that fakes lack.
  • - Out of 18 commercial samples tested, 10 matched the microstructure of genuine agarwood, but 6 were incomplete in resin filling, highlighting the resinous phloem as a crucial feature for authenticating agarwood in trade and regulation contexts.

Xylem-associated fungus can secrete many secondary metabolites to help trees resist various stresses and play a crucial role in facilitating agarwood formation. However, the dynamics of endophytic fungi in xylem after artificial induction have not been fully elaborated. Endophytic fungi communities and xylem physio-biochemical properties were examined before and after induction with an inorganic salt solution, including four different times (pre-induction (0M), the third (3M), sixth (6M) and ninth (9M) month after induction treatment).

Agarwood is resin-containing wood produced by plants that have been injured. It is widely used in herbal medicine, incense, decorative items, and so on. In this study, we conducted resin area statistical analysis, determined starch particle and reducing sugar contents, and performed multivariate statistical analysis of chemical composition by GC-MS and UPLC-Q-TOF-MS to explore the different components in sections cut from an agarwood column, designated as A1-A4.
