【摘要】 骆驼蹄瓣(Zygophyllum fabago L.)为蒺藜科驼蹄瓣属植物,主要分布于西北各省,多生于半荒漠和荒漠地带的干旱地区。其根茎入药,有止咳化痰、止痛消炎的功能。用于支气管炎、感冒、牙痛及顽固性头痛等。为了充分利用我国的植物资源,进一步开发骆驼蹄瓣的药用部位,寻找骆驼蹄瓣的活性成分,我们对骆驼蹄瓣茎进行了系统的化学成分研究。应用多种现代分离方法和技术,从骆驼蹄瓣茎的乙醇提取物中分离得到23个化合物,通过各种波谱技术(包括UV,IR,1H-NMR,13C-NMR,1H-1HCOSY,HMQC,HMBC,NOESY,EI-MS,ESI-MS)和理化常数,鉴定了22个,其中6个为新化合物,8个为首次从驼蹄瓣属植物中分离得到,27-Nor型三萜皂苷也是首次从蒺藜科植物中分离得到。新化合物包括1个27-Nor型三萜皂苷和5个含磺酸基的三萜及其苷类化合物,分别命名为:骆驼蹄瓣皂苷A(fabagoside A,LTB-11),骆驼蹄瓣素(fabagoin,LTB-17),骆驼蹄瓣皂苷B(fabagoside B,LTB-16),骆驼蹄瓣皂苷C(fabagoside C,LTB-19),骆驼蹄瓣皂苷D(fabagoside D,LTB-21),骆驼蹄瓣皂苷E(fabagoside E,LTB-22)。其余成分鉴定为:豆甾4-烯-3-酮(LTB-1),正二十八烷醇(LTB-2),正三十二烷醇(LTB-3),β-谷甾醇(LTB-4),奎洛维酸(LTB-5),胡萝卜苷(LTB-6),3-O-[β-D-quinovopyranosyl]-pyrocincholate(LTB-7),山柰酚(LTB-8),3-O-[β-D-quinovopyranosyl]-cincholic acid(LTB-9),3-O-[β-D-quinovopyranosyl]-quinovic acid(LTB-10),nahagenin(LTB-12),3-O-[β-D-glucopyranosyl]-quinovic acid(LTB-13),腺苷(LTB-14),紫云英苷(LTB-15),3-O-[β-D-2-O-sulphonyl-quinovopyranosyl]-quinovic acid-28-O-[β-D-glucopyranosyl]ester(LTB-18),3″-O-磺酸基紫云英营(LTB-20)。蜀葵(Althaea rosea Linn.Cavan.Diss)为锦葵科蜀葵属植物,产于我国西南地区。全草入药,味甘甜,性凉。有和血止血,解毒散结的功能,主治吐血、衄血、月经过多、赤白带下、二便不通、小儿风疹等。为了更好的开发和利用该药用植物资源,我们对蜀葵花进行了系统的化学成分研究。从蜀葵花的乙醇提取物中分离得到27个化合物,通过各种现代波谱学技术(包括UV,IR,1H-NMR,13C-NMR,1H-1HCOSY,HMQC,HMBC,EI-MS)和理化常数,鉴定了25个化合物,其中1个为新化合物,13个为首次从蜀葵属植物中分离得到。新化合物为黄酮苷类,命名为:蜀葵黄酮苷A(roseside A,SKH-18)。其余成分鉴定为:正二十九烷(SKH-1),棕榈酸乙酯(SKH-2),正二十八烷酸(SKH-3),β-谷甾醇(SKH-4),桂皮酸(SKH-5),茴香酸(SKH-6),阿魏酸(SKH-7),香豆酸(SKH-8),胡萝卜苷(SKH-9),水杨酸(SKH-10),虎耳草苷(SKH-11),柚皮素(SKH-12),5,7,8,4′-四羟基-3-甲氧基黄酮(SKH-13),芹菜素(SKH-14),延胡索酸(SKH-15),山柰酚(SKH-16),(2S,3S)-3,5,7,4′-四羟基二氢黄酮(SKH-17),南酸枣苷(SKH-19),紫云英苷(SKH-20),(2R,3R)-5,7,4′-三羟基二氢黄酮-3-O-β-D-葡萄糖苷(SKH-21),异甘草苷(SKH-22),银椴苷(SKH-23),芦丁(SKH-24),杨梅黄素3-O-β-D-葡萄糖苷(SKH-25)。在化学工作的基础上,我们运用MTT法对骆驼蹄瓣茎和蜀葵花中分离得到的部分单体化合物进行了体外抗肿瘤活性的研究,发现5个来自骆驼蹄瓣的化合物具有显著的抗肿瘤活性。总结讨论了骆驼蹄瓣中三萜皂苷类成分的分离方法、波谱特征及生物来源等,同时还总结讨论了蜀葵花中黄酮类成分的分离方法和波谱特征。为这两种类别化合物的分离和结构鉴定提供了依据。本文还对驼蹄瓣属和蜀葵属植物的化学和药理学研究的概况进行了综述,为开发利用这两个属的药用植物资源奠定了基础。

【Abstract】 Zygophyllum fabago L. belongs to the Zygophyllaceae family, Zygophyllum genus. It is widely distributed in northwest region of China. The roots and barks of the plant were used as antibacterial, anti-inflammatory and analgesic agents. In order to make further use of the Chinese herbal resources and find active compounds, we have undertaken a systematic investigation on the chemical constituents of the barks of Zygophyllum fabago L.Twenty three compounds were isolated from the ethanolic extracts of the barks of Zygophytlum fabago L. Twenty two of them were identified by using various modern spectrometric approaches, including UV, IR, 1H-NMR, 13C-NMR, 1H-1H COSY, HMQC, HMBC, NOESY, EI-MS, ESI-MS etc., of which six were new compounds, eight isolated from the genus for the first time, and 27-nor-triterpenoid glycosides were isolated from the Zygophyllaceae family for the first time. Among these new compounds, there were one 27-nor-triterpenoid glycoside and five teiterpenoid and saponins with sulfo group, named fabagoside A (LTB-11), fabagoin(LTB-17), fabagoside B (LTB-16), fabagoside C (LTB-19), fabagoside D (LTB-21) and fabagoside E (LTB-22).

Cavan. Diss were tested for the antitumour activities in vitro. The results indicated that five compounds isolated from Zygophyllum fabago L. showed some antitumour activities. In addition, the thesis also reviewed the research advances of the chemical constituents and pharmacological activities of Zygophyllum genus and Althaea genus.
