Phenolic Compounds from Arundina graminifolia and Their Anti-Tobacco Mosaic Virus Activity

Two new diphenyl ethers from Acanthopanax senticosus (Rupr. & Maxim.) Harms with PTP1B inhibitory activity

“…1) were obtained from A. senticosus. The known compounds were identified as sinapaldehyde (3) (Baucher et al, 1998), isovanillin (4) (Ryu et al, 2004), 2,6-dimethoxybenzoic acid phenylmethylester (5) (Lu et al, 1993), gramniphenol A (6) (Gao et al, 2012), (À)-syringaresinol (7) (Deyama, 1983), syringin (8) (Nishibe et al, 1990), (E)-2,3,5,4 0 -tetrahydroxystilbene-2-O-b-Dxyloside (9) (Sun et al, 2013) and torachrysone-8-O-b-D-glucoside (10) (Sun et al, 2013) based on the NMR data. Of these, compounds 6,9 and 10 were reported in this plant for the first time.…”

Two New Stilbenoids from the Aerial Parts of Arundina graminifolia (Orchidaceae)

“…Its striking purple flowers are the reason for its harvest for ornamental purposes [9]. Stilbenoids are the major secondary metabolites reported in this orchid based on previous phytochemical studies, revealing an important structural diversity of diphenylethylenes [10][11][12][13][14], bibenzyls [15][16][17][18], phenanthrenes [19], 9,10-dihydrophenanthrene derivatives [20] and other phenolic compounds [21][22][23][24][25][26], and thus could be considered as potential chemotaxonomic markers for the genus. These metabolites are also known to display a wide range of biological activities such as antioxidant, antiviral, cytotoxic and antitumoral properties [27][28][29][30][31][32].…”

A New Cytotoxic Stilbenoid from Arundina graminifo

“…It has been widely used for clearing heat, detoxicating and dissipating blood stasis by Dai people lived in Xishuangbanna, Yunnan province of China 2 . Previous phytochemical studies of A. graminifolia have shown the presence of stilbenoids 3 , dibenzyls 4 , phenanthrenes 5,6 and other phenolic compounds 7,8 . In our previous studies, some new phenolic compounds possessing anti-tobacco mosaic virus (anti-TMV) and anti-HIV-1 properties were isolated from A. gramnifolia grown in the Xishuangbanna and Honghe Prefecture 7,8 .…”

In our previous studies, some new phenolic compounds possessing anti-tobacco mosaic virus (anti-TMV) and anti-HIV-1 properties were isolated from A. gramnifolia grown in the Xishuangbanna and Honghe Prefecture 7,8 . Motivated by a search for new bioactive metabolites from local plants, our group has reinvestigated the chemical constituents of the whole plant of A. graminifolia growing in the Honghe Prefecture, Yunnan province, which led to the isolation and characterization of a new stilbenoid gramniphenol K (1).…”
