摘要

在本文中,我们报道了四种新化合物在大黄叶乙醇提取物中出现,以及其他先前在该物种中报道的化合物。采用柱层析、傅里叶变换红外(FTIR)和气相色谱/质谱法对化合物进行了分离和表征。提取液的FTIR光谱显示酚OH拉伸(3362.30 cm-1), C=O (1660.08 cm-1), CO拉伸(1369.46 cm-1和1319.00 cm-1)和CN拉伸(1072.44 cm-1),证实了醇类、羧酸类和含氮化合物的存在。初步鉴定出齐墩果酸(1)、齐墩果酸乙酸(2)、蝶呤-6-羧酸(3)、十一醇(4)、白桦酸(5)、白桦素(6)和苯甲醇(7)。化合物1 ~ 4为首次从芫荽中分离得到。

Two New Pentacyclic Triterpenoids, an Alkaloid and a Long-chain Fatty Acid from Albizia Coriaria (Welw ex. Oliver)
Herein, we report the occurrence of four new compounds in ethanolic extract of Albizia coriaria Welw ex. Oliver leaves along with other compounds previously reported in this species. The compounds were isolated and characterized using column chromatography, Fourier Transform Infrared (FTIR) and gas chromatography/mass spectrometry. FTIR spectrum of the extract showed phenolic OH stretching (3362.30 cm-1), C=O (1660.08 cm-1), CO stretching (1369.46 cm-1 and 1319.00 cm-1) and CN stretch (1072.44 cm-1) which confirmed the presence of alcohols, carboxylic acids and nitrogen-containing compounds. Oleanolic acid (1), oleanolic acid acetate (2), pterin-6-carboxylic acid (3), undecanol (4), betulinic acid (5), betulin (6) and benzyl alcohol (7) were tentatively identified in the extract. Compounds 1-4 are being reported for the first time in Albizia coriaria.
