AI Article Synopsis
- Dalbergiae Odoriferae Lignum is a valuable and rare hardwood from the endangered Dalbergia odorifera tree in China, leading to high demand and price.
- Researchers explored D. catifolia as a potential substitute by extracting and analyzing its heartwood using various chromatography techniques, identifying a total of sixteen unique neoflavonoids.
- The study found that some compounds were identified for the first time from both D. catifolia and D. latifolia, with ten neoflavonoids common to D. odorifera and D. latifolia.
Article Abstract
Dalbergiae Odoriferae Lignum is derived from heartwood of Dalbergia odorifera,which is national Ⅱ level of rare and endangered protective plants in China. Its resources are scarce and its price is high. In order to find substitutes of D. odorifera,the chemical constituents of 70% ethanol extract of heartwood of D. catifolia were systematically studied by using silica gel,Sephadex LH-20 column chromatography,and semi-preparative HPLC. Sixteen neoflavanoids were isolated and identified as eight dalbergiphenols( 1-8),three dalbergiones( 9-11),two dalbergins( 12,13),two benzophenones( 14,15) and one other type neoflavanoids( 16) based on spectroscopic data analyses and/or comparing the spectroscopic data with those in literature. Among them,compounds 3,7 and 11 were isolated from the genus Dalbergia for the first time,and compounds 2,4-6,8,14 and 15 were isolated from the D. latifolia for the first time. Ten neoflavonoids were both discovered from D. latifolia and D. odorifera.
