    Inhibitory effects of norlignans isolated from Anemarrhena asphodeloides on degranulation of rat basophilic leukemia- 2H3Cells.[Pubmed: 27780134 ]
    Anemarrhena asphodeloides is known to suppress inflammation and lower various fevers. To determine the active component of A. asphodeloides, ethanol (EtOH) extract of A. asphodeloides rhizomes was fractionized. The compounds isolated from the dichloromethane (CH2Cl2) soluble fraction were identified as 4'-O-Methylnyasol (1), nyasol (2), 3″-methoxynyasol (3), 3″-hydroxy-4″-methoxy-4″-dehydroxynyasol (4), 4-hydroxybenzaldehyde (5), and 4-hydroxyacetophenone (6). The four norlignans (1-4) potently inhibited the release of β-hexosaminidase from immunoglobulin E (IgE)/dinitrophenol-conjugated bovine serum albumin (DNP-BSA)-treated rat basophilic leukemia (RBL)-2H3 and A23187 plus phorbol 12-myristate 13-acetate co-treated isolated rat primary mast cells, as markers of degranulation and histamine release. The intraperitoneal treatment with the EtOH extract significantly suppressed the fetal reaction, and serum histamine release induced by compound 48/80 in mice. These results suggest that the four active norlignan compounds and the EtOH extract of A. asphodeloides may have potential to be developed as medicines for the treatment of allergies by inhibiting the activation of mast cells.

    Preparative isolation and purification of four compounds from the Chinese medicinal herb rhizoma Anemarrhenae by high-speed counter-current chromatography.[Pubmed: 16364341]
    High-speed counter-current chromatography (HSCCC) was applied to the separation and purification of mangiferin, neomangiferin, cis-hinkiresinol and (-)-4'-O-Methylnyasol from the Chinese medicinal herb rhizoma Anemarrhenae. Five hundred milligrams of crude extracts were separated by using n-butanol-acetic acid (1%) (1:1, v/v) as the two-phase solvent system and yielded 35.3 mg of neomangiferin and 245.4 mg of mangiferin. During this separation, cis-hinkiresinol and (-)-4'-O-Methylnyasol were still maintained in the stationary phase. The stationary phase was collected, evaporated to dryness and separated with light petroleum-ethyl acetate-methanol-water (1:1:1.2:0.8, v/v) and 1:1:1.4:0.6 (v/v) in gradient elution, which yielded 17.2 mg of cis-hinkiresinol and 12.4 mg of (-)-4'-O-Methylnyasol. The purities of mangiferin, neomangiferin, cis-hinkiresinol and (-)-4'-O-Methylnyasol were 96.3, 98.0, 97.3 and 98.2%, respectively, as determined by HPLC. The chemical structures of these components were identified by 1H NMR and 13C NMR.
