中文摘要:采用小孔树脂、凝胶SephadexLH-20、反相色谱ODS及制备型高效液相色谱(Pre-HPLC)等分离技术,从坡柳Dodonaea viscosa(Linn.) Jacq.Enum.种子乙醇提取物中分离获得1个活性化合物。通过质谱及核磁共振等波谱技术,鉴定其为新的齐墩果烷型三萜皂苷类化合物21-epoxyangeloyl-15,16,28-tirhydroxy-22-(2-methylbutanoyl)-Olean-12-en-3-(O-α-L-arabinofuranosyl-(1→3)-O-[β-D-glucopyranosyl-(1→2)]-β-D-glucuronide,命名为坡柳皂苷A,英文名dodoneaviscoside A。生物活性测定结果表明,其对小菜蛾Plutella xylostella(L.)3龄幼虫具有较好的非选择性拒食活性,24 h拒食中浓度(AFC50)为207.4 μg/mL。值得进一步研究。 |

Abstract:A bioactive compound was obtained from the ethanol extract of the Dodonaea viscosa (Linn.) Jacq. Enum. seeds using separation technologies including pore resin, gel SephadexLH-20, reversed phase chromatography ODS and preparative high performance liquid chromatography (Pre-HPLC). The structures of compound 1 were characterized by NMR experiments and mass spectrometry as a new oleanane-type triterpenoid, 21-epoxyangeloyl-15,16,28-tirhydroxy-22-(2-meth-ylbutanoyl)-Olean-12-en-3-(O-α-L-arabinofuranosyl-(1→3)-O-[β-D-glucopyranosyl-(1→2)]-β-D-glucuronide. It was named as dodoneaviscoside A. The results of the bioactivity determination showed that dodoneaviscoside A had antifeedant activity against the 3th instar larvae of Plutella xylostella (L.) with AFC50 value of 207.4 μg/mL. As a new compound with good nonselective antifeeding activity to P. xylostella, the potential applicatio of dodoneaviscoside A is worth of further investigation. |
