Rapid authentication of agarwood by using liquid extraction surface analysis mass spectrometry (LESA-MS).[Pubmed:32342587]
Phytochem Anal. 2020 Apr 27.
INTRODUCTION: Agarwood is a highly valuable fragrant resinous wood which is widely used as traditional Chinese medicines, perfumes, incense and decorations. Due to its high economic value and excessive demand, this leads to a rising price and proliferation of fake commodities. Thus, strict authenticity identification and quality evaluation of agarwood are of great significance. OBJECTIVE: To establish a simple, rapid and non-destructive technique for identifying the authenticity of agarwood. METHODS: Liquid extraction surface analysis mass spectrometry (LESA-MS) was firstly proposed to identify the authenticity of 62 agarwood samples without sample preparation. In addition, multivariate statistical models and thin-layer chromatography (TLC) method were used to analyse and verify the results of LESA-MS. RESULTS: Representative compounds of agarwood were detected by LESA-MS. A characteristic 2-(2-Phenylethyl)chromone compound (m/z 319.1) was treated as a key chemical marker to identify agarwood and its counterfeits rapidly. Several other chromones ions were identified and used as additional evidence for authentic samples. A total of 62 samples were visually discriminated as two groups by principal component analysis (PCA) and orthogonal projection to latent structures discriminant analysis (OPLS-DA), and the specific characteristic marker was highlighted. Moreover, the qualitative results of the conventional TLC method were in agreement with the LESA-MS approach. CONCLUSION: The proposed LESA-MS method was successfully applied in the direct qualitative analysis of agarwood from different sources. This study indicated great feasibility and practicality of LESA-MS in the rapid identification of agarwood, and provided a non-destructive and meaningful preliminary screening tool for the agarwood industry.
Five new 2-(2-phenylethyl)chromone derivatives from agarwood.[Pubmed:32335822]
J Nat Med. 2020 Jun;74(3):561-570.
Agarwood has been used as an incense and in traditional medicines as aphrodisiac, sedative, cardiotonic, and carminative. In this study, five new 2-(2-Phenylethyl)chromones (2, 13-16) and eleven known compounds (1, 3-12) were isolated from the agarwood. The structures of the new compounds were determined by (1)H-, (13)C-, and two-dimensional NMR together with electronic circular dichroism (ECD) spectroscopy. All isolated compounds were evaluated for the phosphodiesterase (PDE) 3A and 5A1 inhibitory activity by the fluorescence polarization method. Dimeric 2-(2-phenylehyl)chromones (13, 14, 16) had potent inhibitory activity to PDE 5A1 with IC50 values of micro molar range (13: 4.2 muM, 14: 7.9 muM, 16: 4.3 muM), whereas they had weak activity to PDE 3A. In contrast, compound (15), which has a phenylpropionic acid moiety instead of the 2-(2-Phenylethyl)chromone moiety in the dimers, showed moderate inhibition of both PDE 3A (IC50: 42.6 muM) and PDE 5A1 (IC50: 15.1 muM).
