“…Naringenin is the predominant flavanone in grapefruit and has antioxidant, anti-inflammatory, and antitumor activities [20]. This com- pound has been isolated from D. dendiflorum and D. trigonopus [21,22], and in this study, was present in all tested Dendrobium species. Our results showing the wide distribution of moscatilin and giganol in Dendrobium as major bibenzyl constituents were similar to those of Yang and colleagues [8].…”

The aim of this study was to establish a method for discriminating Dendrobium officinale from four of its close relatives Dendrobium chrysanthum, Dendrobium crystallinum, Dendrobium aphyllum and Dendrobium devonianum based on chemical composition analysis. We analyzed 62 samples of 24 Dendrobium species. High performance liquid chromatography analysis confirmed that the four low molecular weight compounds 4′,5,7-trihydroxyflavanone (naringenin), 3,4-dihydroxy-4′,5-dimethoxybibenzyl (DDB-2), 3′,4-dihydroxy-3,5′-dimethoxybibenzyl (gigantol), and 4,4′-dihydroxy-3,3′,5-trimethoxybibenzyl (moscatilin), were common in the genus. The phenol-sulfuric acid method was used to quantify polysaccharides, and the monosaccharide composition of the polysaccharides was determined by gas chromatography. Stepwise discriminant analysis was used to differentiate among the five closely related species based on the chemical composition analysis. This proved to be a simple and accurate approach for discriminating among these species. The results also showed that the polysaccharide content, the amounts of the four low molecular weight compounds, and the mannose to glucose ratio, were important factors for species discriminant. Therefore, we propose that a chemical analysis based on quantification of naringenin, bibenzyl, and polysaccharides is effective for identifying D. officinale.

“…The plants of this genus contain bibenzyls (Li et al, 2009), phenanthrenes (Lee et al, 2009;Wang et al, 2009), anthraquinones (Lin et al, 2001), fluoro-derivatives (Zhang et al, 2007), coumarins (Zhang et al, 2005), sesquiterpenes (Zhang et al, 2008) and alkaloids (Wang and Zhao, 1985). Some of these compounds have also been reported as having antioxidant, anti-inflammatory (Zhang et al, 2007), antifibrotic (Yang et al, 2007a), immunomodulatory ) and anti-platelet aggregation activities (Fan et al, 2001).…”

“…Among the Dendrobium genus, most studies have focused on the bioactivity and structural types of some small molecules, such as bibenzyl, phenanthrene, anthracene, fluorene, coumarin, flavone, cinnamate, sesquiterpene, sterol, fatty acid, and alkaloids [2][3][4][5][6][7][8][9][10][11][12]. However, the polysaccharide constituents were much less investigated.…”
