Abstract:
Objective: To study the antiviral constituents from the active fraction of Re-Du-Ning (RDN) Injection. Methods: In this study, the active fraction of RDN Injection was screened by the mice model loaded with restraint stress infected with influenza virus. The chemical constituents were isolated by chromatography on silica gel, ODS, Sephadex LH-20 & Toyopearl HW-40 columns, and reverse phase MPLC & HPLC repeatedly. Their structures were identified by spectral data and physicochemical property. Results: The 95% ethanol eluate of RDN Injection on the macroporous adsorption resin column was proved to be the antivirus active fraction of RDN Injection. Fourteen compounds were isolated and identified as (2E,6S)-8-[α-L-arabinopyranosyl-(1″-6')-β-D-glucopyranosyloxy]- 2,6-dimethylct-2-eno-1,2″-lactone (1), lyoniresinol (2), 5'-methoxyisolariciresinol (3), ent-isolariciresinol (4), (7R,8R)-4,7,9,9'- tetrahydroxy-3,3'-dimethoxy-8-O-4'-neolignan (5), (7S,8R)-4,7,9,9'-tetrahydroxy-3,3'-dimethoxy-8-O-4'-neolignan (6), ceplignan (7), 5'-methoxyceplignan (8), (-)-dihydrodehydrodiconiferyl alcohol (9), (7S,8R)-3,3',5-trimethoxy-4',7-epoxy-8,5'-neolignan-4,9,9'-triol (10), (2-cis, 4-trans)-abscisic acid (11), (2-trans, 4-trans)-abscisic acid (12), (1S,3R,4R,5S,7R,9R)-decane-6-carboxylic acid (13), and (1S,3R,4S,5S,7R,9R)-decane-6-carboxylic acid (14); Among them, compound 1 exhibited the antivirus activity against Dengue virus. Conclusion: Compound 8 is a new compound and the other isolated compounds are reported from RDN Injection for the first time, and compound 1 shows the anti-virus activity against Dengue virus.
