Diterpenoid alkaloids from roots of Aconitum recemulosum and their inhibitory effects on PAF-induced platelet aggregation / 中国中药杂志

<p><b>OBJECTIVE</b>To study diterpenoid alkaloids from the roots of Aconitum recemulosum, and their inhibitory effects on PAF-induced platelet aggregation.</p><p><b>METHOD</b>The root of A. recemulosum was extracted with 95% EtOH. The total alkaloids extracted were isolated and purified by several kinds of column chromatography over silica gel, RP-18, and Sephadex LH-20, and identified based on spectral analysis. And the inhibitory effects of isolated compounds on PAF-induced platelet aggregation were detected.</p><p><b>RESULT</b>Five alkaloids were isolated and identified as sachaconitine (1), 14-acetylsachaconitine (2), hemsleyanine C (3), circinasine A (4), and talatisamine (5). The results showed compounds 1 and 2 have moderate inhibition effect on PAF.</p><p><b>CONCLUSION</b>Compounds 1-5 were firstly isolated from this plant. Furthermore, compounds 1 and 2 possessed moderate inhibitory effects on PAF-induced platelet aggregation.</p>

Effect of Macleaya cordata alkaloids on five skin fungus / 中成药

AIM:To research inhibitory effects of plumepoppy (Macleaya cordata) extract on dermophytosis. METHODS:A series of experimental methods,including agar hole method,plate dilution method and solid medium dilution method were initiated into pathogenic organism of skin disease,including Trichophyton rubrum(Tru),Trichophyton schoenleini(Ts),Trichophyton rosaceum(Tro),Trichophyton mentagrophytes(Tm),and Epidermophyton floccosum(Ep) to determinate in vitro antibacterial Minimum inhibitory concentration(MIC) by plumepoppy extract that macerated with acidic water (pH = 3). RESULTS:Macleaya cordata alkaloids had significant effect on these five kinds of skin fungi. The MIC of Tru,Ts,Ep was 1. 6 mg/mL; The MIC of Tro and Tm was 0. 8 mg/ mL. CONCLUSION:The plumepoppy extract has anti-fungus activaties,with the increasing concentration,the inhibition effect rapidly goes up.
