目的:研究马鞭草科紫珠属植物藤紫珠的化学成分。方法:应用多种色谱方法进行分离纯化,综合运用紫外光谱、红外光谱、质谱以及核磁共振光谱等现代波谱学方法和技术鉴定化合物的结构。结果:从藤紫珠甲醇提取物的乙酸乙酯萃取部位中分离得到10个化合物,分别鉴定为:齐墩果酸(1)、2β,3β,19α-三羟基熊果酸(2)、木犀草素-7,4'-二甲醚(3)、木犀草素-3',4',7-三甲醚(4)、木犀草素-4'-甲醚(5)、次大风子素(6)、木犀草素(7)、lyoni-resinol 3α-O-β-D-glucopyranoside(8)、3,4,5-三甲氧基苯酚-β-D-呋喃芹糖氧基-(1→6)-β-D-吡喃葡萄糖苷(9)、山柰酚-3-O-β-D-葡萄糖醛酸苷(10)。结论:以上化合物均为首次从藤紫珠中分离得到,其中,化合物3、4、6、8和10为首次从紫珠属植物中分离得到。
Objective : To study the chemical constituents of Callicarpa peii, Methods : The chemical constituents were isolated and purified by chromatographic methods and elucidated by spectral analysis, including UV, IR, MS, 1H-NMR and 13 C-NMR. Results : Ten compounds were obtained and identified as oleanolic acid ( 1 ), 2/3,3/3,19 a-trihydroxy-12-en-28-ursolic acid ( 2 ), luteolin -7,4 '-dimethylether ( 3 ), luteolin -3', 4', 7, -trimethylether ( 4 ), luteolin -4'-methylether ( 5 ), hydnocarpin ( 6 ), luteolin ( 7 ), lyoniresinol 3 a- O-β-D- glucopyranoside ( 8 ), kelampayoside A (9), kaempferol -3-O-glucuronide (10). Conclusion : All these compounds are isolated from Callicarpa peii for the first time and compounds 3,4,6,8 and 10 are isolated from this genus for the first time .
