摘要

本研究从新鲜马蹄苋（Portulaca oleracea L.）根中分离得到3种同型异黄酮，并建立了电喷雾电离（ESI）质谱破碎途径。将碎片化规律成功应用于马齿苋鲜、干中同型异黄酮的分析，用HPLC-DAD-ESIMS2对28种同型异黄酮进行了鉴定或初步表征。该批甘蓝干、鲜药材中同型异黄酮含量差异不显著，需要更多不同地区的样品进一步比较。

Characterization of homoisoflavonoids in fresh and dried Portulaca oleracea L. by HPLC-DAD-ESIMS2

In the study, three types of homoisoflavonoids were isolated from the roots of fresh Portulaca oleracea L. The electrospray ionization (ESI) mass spectral fragmentation pathways of these compounds were proposed. The fragmentation rules were successfully applied for the analysis of the homoisoflavonoids of the fresh and dried Portulaca oleracea L. A total of 28 homoisoflavonoids were identified or tentatively characterized by HPLC-DAD-ESIMS². There were no significant differences of homoisoflavonoids detected in this batch of dried and fresh herbs of P. oleracea L. More samples from various areas are needed to further compare the differences of homoisoflavonoids between them.

期刊介绍： The Journal of Asian Natural Products Research (JANPR) publishes chemical and pharmaceutical studies in the English language in the field of natural product research on Asian ethnic medicine. The journal publishes work from scientists in Asian countries, e.g. China, Japan, Korea and India, including contributions from other countries concerning natural products of Asia. The journal is chemistry-orientated. Major fields covered are: isolation and structural elucidation of natural constituents (including those for non-medical uses), synthesis and transformation (including biosynthesis and biotransformation) of natural products, pharmacognosy, and allied topics. Biological evaluation of crude extracts are acceptable only as supporting data for pure isolates with well-characterized structures. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymized refereeing by at least two expert referees.
