To examine the capacity of alkaline resistance of Albizzia julibrissin Durazz seedlings,the contents of MDA,soluble sugar and proline,and the activity of POD and SOD in Albizzia julibrissin durazz tree body were measured by means of visible spectrophotometry.

为检测合欢幼苗的抗碱胁迫能力，文章试验利用可见分光光度法测定了碱胁迫下合欢幼苗体内的丙二醛、可溶性糖、脯氨酸含量及POD、SOD活性，分析这些生理指标在不同处理浓度、不同处理时间下的变化规律，探求碱胁迫下合欢幼苗的抗逆生理机制。

Methods Wistar rats were fed with highfructose diet for 12 weeks to induce Type 2 diabetes meilitus. Forty Wistar rats were randomly divided into 5 groups: a control group; a diabetic group; and a low (1 mg/kg), medium (5 mg/kg), or high (10 mg/kg) dose of arecoline groups.

采用高果糖饲料饲养Wistar大鼠12周制备2型糖尿病大鼠模型，40只实验动物随机分为5组：对照组、模型组、模型+1 mg/kg槟榔碱组、模型+5 mg/kg槟榔碱组、模型+10 mg/kg槟榔碱组。

By identifying the obtained components by TLC, three alkaloids components were detected, among which one was nuciferine. The other two were N-Nornucirerine and O- Nornucirerine, identified by Nuclear Magnetic Resonance and Mass Spectrum.6、In order to exploit natural bacteriostat of lotus leaves, optimal extraction process and antibacterial characteristics were studied.

两者得到的化合物分别经TLC鉴别，得到3个生物碱成分，其中1个为荷叶碱，其余两个应用核磁共振和质谱等技术鉴定为N-去甲荷叶碱和0-去甲荷叶碱。6、从荷叶天然食品抑菌剂开发的角度，研究了荷叶抑菌有效成分的提取优化工艺及抑菌特性。

The results demonstrated that the intracellular pH change was different when the Hela cells was treated with different anti-tumor drugs, some would caused intracellular acidification, some would caused ntracellular basification, and some would barely caused pH change. The single living Hela cells uptaken with the ratiometric pH nanosensor was also imaged with laser confocal microscope, which were treated with anti-tumor drugs.

通过利用该纳米传感器对硫酸长春新碱诱导后的Hela细胞内pH变化的活体、原位、实时监测，发现在硫酸长春新碱诱导引起凋亡的Hela细胞中，细胞内的pH值由诱导前的7.11酸化为6.51，并且在一定的浓度和时间范围内，硫酸长春新碱诱导后细胞内的酸化率与诱导药物的浓度和诱导时间成正相关关系。

There is a good market for betaine,So its synthetic method and purification have captured people's attention.

在介绍甜菜碱市场现状，发展前景及传统生产方法的基础上，重点论述了萃取结晶法生产甜菜碱的原理、特点、萃取剂的选择等，证明萃取结晶法提纯甜菜碱是可行的。

Brucine and its liposome could inhibit the growth of transplanted solid tumor and the inhibitory effect of its liposome is much stronger than that of brucine.

马钱子碱及其脂质体有显著的抑制荷瘤小鼠肿瘤生长作用，马钱子碱脂质体抗肿瘤作用明显强于马钱子碱。

The young common carp was fed with trial diets added respectively L-carnitine byo,0.5×10-4,1.0×10-4,1.5×10-4,2.0×10-4,2.5×10-4 to compare the fat digestibilities of the diets with control diet and get fitting additive number.

分别用在每kg饲料中添加了0、50、100、150、200、250mg纯肉毒碱的饲料饲养鲤春片鱼种，用全收粪法测定鲤对每种饲料粗脂肪的消化率，比较不同添加量的肉毒碱对鲤春片鱼种饲料粗脂肪消化率的影响，旨在寻求鲤春片鱼种中肉毒碱的适宜添加量。

A new method for the determination of vauqueline by using the flow injection chemiluminescence method is presented.

报道一种微量测定马钱子碱的新方法，该方法是基于高锰酸钾对马钱子碱的氧化作用，建立了微量马钱子碱的流动注射化学发光分析法。

We attached for the first time -NOBIN to Frechet-type dendron units. The syntheses of 16 kinds of dendrimer-based NOBIN Schiff-base ligands were achieved in a straightforward manner by simple condensation of -NOBIN with the corresponding salicylicaldehyde derivatives, of which 12 belong to the dendritic Schiff-base ligands and 4 belong to the non-dendritic Schiff-base ligands.

通过手性拆分获得了光学纯化合物NOBIN，首次将NOBIN手性单元连接到树枝状大分子中去，设计合成了四个系列16种新的NOBIN衍生的希夫碱三齿手性配体，其中4种为非树枝状手性希夫碱配体，12种为树枝状手性希夫碱配体。
