植物化学

With its unique molecular structure and outstanding bio-activities, qinghaosu has been proven as a worthy subject for in-depth studies with profound influence, not only for pharmacy, but also for phytochemistry, biogenetic synthesis and organic synthetic chemistry, chemical biology, etc. A great amount of work has been done in the last 30 years, with a lot more issues to be explored. Researchers need to seize the opportunity and make more achievements.

青蒿素以其独特的分子结构和杰出的生物活性显示出它是一有深远影响的研究对象，不仅对于药学，而且对于植物化学、生源合成、有机合成化学、化学生物学等学科都是一个可以大有作为的课题。30年来国内外已做了不少工作，但是还有更多的问题有待探索，机不可失，时不再来，期待着在綻放青蒿素的故土上结出更多的果实。

The phytoestrogen is phytochemistry ingredient that widespread existence in the natural plant and it has the estrin type and/or the anti- estrin active, is the nearly more than ten for years research hot spot.

The Plant Natural Products and application is a cross course concerning plant physiology, phytochemistry, plant pharmacy, biological agricultural chemicals, food processing, ecology and so on, which is a quickly developing research field in recent years.

植物天然产物与应用》是植物生理学、植物化学、植物药学、生物农药、食品加工、生态学、园林植物等课程的交叉课程，是近几年发展比较快的一个研究领域。

There are a number of reasons why you should consider taking a dietary supplement. For a start, few of us eat an adequate amount of phytochemically-rich fruits and vegetables each day. Phytochemicals have been shown to have a positive impact on reducing the risk of degenerative diseases, but most people consume a very limited selection of good foods on a regular basis.The fact is that variety in your diet is important to guarantee you get enough of the 45 known essential nutrients that maintain the body's health.

人体需要营养补充品的理由有很多，因为只有小部份的人能够从日常饮食中进食充足份量含丰富植物化学素的蔬果，而大部份人会惯常地食用某几类食物，但选择不同种类的食物是很重要的，这样才可确保人体得到45已知的必须营养及多种重要的植物化学素，这些都证实有效减少变性疾病。

Based on relative literatures,this part has included five resesearch aspects as below.1 Fifteen compounds were isolated and purified by extraction,column chromatography,and their structures were determined on the basis of spectral analysis: acteoside(Ⅰ-1),isoacteoside(Ⅰ-2),crenatoside(Ⅰ-3),cistanoside F(Ⅰ-4),sinapoyl-4-O-β-D-glucoside(Ⅰ-5),adenosine(Ⅰ-6),β-siterol(Ⅰ-7),oleanic acid(Ⅰ-8), succinic acid(Ⅰ-9),caffeic acid(Ⅰ-10),protocatechuic aldehyde(Ⅰ-11),p-hydro xybenzyl alcohol(Ⅰ-12),β-daucosterol(Ⅰ-13),D-galacitol(Ⅰ-14),D-mannitol(Ⅰ-15).Ⅰ-4～15 were obtained from this plant for the first time,andⅠ-6,7,9,and 13 were isolated from Orobanche genus for the first time.2 The scavenging test of DPPH showed that most compounds have comparative antioxidant activity as L-ascorbic acid and part of them show better activity such as the O.coerulescens extract and phenylethanoid glycosides.Acteoside showed potent free radical scavenging effects with a median inhibition concentration of 25.6μg/ml.3 The anti-HBV activities of acteoside,isoacteoside and crenatoside were measured,and all of them showed suppressive activity on the expression of HBsAg and HBeAg in the HepG2.2.15 cell line.

本论文在文献调研基础上对紫花列当化学成分及生物活性进行了研究，并从免疫抗病毒角度探讨紫花列当中特征性成分类叶升麻苷的肝保护作用及其机制。1采用大孔树脂、硅胶和Sephadex LH-20等色谱技术对紫花列当进行系统的植物化学研究，从中分离得到19个化合物，利用UV和NMR等波谱手段及理化性质鉴定了其中的15个化合物，分别为类叶升麻苷(Ⅰ-1)、异类叶升麻苷(Ⅰ-2)、crenatoside(Ⅰ-3)、cistanoside F(Ⅰ-4)、sinapoyl-4-O-β-D-glucoside(Ⅰ-5)、腺苷(Ⅰ-6)、β-谷甾醇(Ⅰ-7)、齐墩果酸(Ⅰ-8)、琥珀酸(Ⅰ-9)、咖啡酸(Ⅰ-10)、原儿茶醛(Ⅰ-11)、对羟甲基苯甲酸(Ⅰ-12)、β-胡萝卜苷(Ⅰ-13)、D-半乳糖醇(Ⅰ-14)和甘露醇(Ⅰ-15除化合物Ⅰ-1、Ⅰ-2和Ⅰ-3外，其余化合物均为首次从该植物中分离得到。2)通过大孔树脂富集该药材有效部位苯乙醇总苷，并采用HPLC测得其所含特征性成分类叶升麻苷的含量可达80%以上。3DPPH自由基清除试验显示紫花列当提取物及其所含的苯乙醇苷类化合物均具有较好的抗氧化能力，其清除DPPH自由基能力接近于抗坏血酸。4采用卡介苗整体致敏、脂多糖离体攻击构建大鼠原代肝细胞免疫性损伤模型，在体外观察类叶升麻苷的保肝作用。
