This paper studies the growth curve and content variation of suger, titratable acid and Vitamine C, which in the two main wampee cultivars Clausena lansium (Lour. Skeels cv.

研究了黄皮两个主要栽培品种鸡心黄皮和郁南无核黄皮果实生长动态及其发育过程中糖、酸和维生素C含量的变化规律。

Low temperature significantly prolonged fruit storage life,delayed the total sugar,total acid and V_C content loss.Between 2 ℃ and 12 ℃,the lower the storage temperature,the better preservation effect.The best storage temperature of wampee was 2-4 ℃. MAP storage could delay the!quality loss of wampee.0.025 mm polyethylene film with the packing capacity of 5.4 kg·m~(-2) were recommended.

结果表明，常温下黄皮果实贮藏期短，常温贮藏3 d后，好果率低于75%；低温能明显延长果实的贮藏期，延缓果实的糖、酸和VC含量的下降；在2-12 ℃间，贮藏温度越低，保鲜效果越好，适宜的贮藏温度为2-4 ℃；采用MAP保鲜技术能延缓果实品质的下降，在2-4 ℃下大鸡心黄皮MAP保鲜的适宜条件是采用0.025 mm的PE膜包装，装果量为5.4 kg·m-2。

Effects of different fruit-retaining reagents upon fruiting on Yunan seedless wampee;2. To probe into the seedless reason of fruit of the Linyuan 1 seedless wampee ,the Linyuan 1 seedless wampee is observed at its flower organs, pollen quantity and degree of satiation, and germination, and compared with the seed wampee.

为了探讨林院 1号无核黄皮果实无籽的原因，于 1992年～ 2 0 0 0年在广西大学林学院观察林院 1号无核黄皮的花器、花粉数量及饱满程度、花粉萌发情况，并和有核黄皮比较；采用随机区组试验设计，对林院 1号进行自然授粉、去雄不授粉套袋、去雄后用有核黄皮花粉授粉并套袋的授粉试验；观察林院 1号的授粉受精过程。

Genetic distance data showed that the heriditary conservation among 11of 14 studied cultivars (except Longshan akaryotic wampee, Longchuan akaryotic wampee and white sugar karyotic wampee) was very high (D≤0.1), which suggested that the genetic relationship between theses cultivars was very close.

结果表明，除龙川无核黄皮、龙山无核黄皮和冰糖黄皮外，其它11个品种间的遗传距离较近（D≤0.1），说明大多数黄皮品种遗传差异较小，亲缘关系较近。

The analogs of piracetum with the core of demethylclausenamide(III-4 and III-5) were prepared by condensation of demethylclausenamide with ethyl bromoacetate and hydrolysis or aminolysis there after.

3在兰培工作的基础上，选用O-乙酰-R--扁桃酸为拆分剂，成功的拆分了表黄皮酰胺前体5--4-苯基-1-甲基吡咯烷酮(Ⅱ-1)，和Ⅱ-1分别引入3位羟基得到和表黄皮酰胺。

Zhang Li-contracted land is fertile, and adequate water is very suitable for cultivating seedlings, cultivating 10,000 has more than 80 high-quality seedlings Aquilaria .10 10000 Mission many trees and 10,000 more than 20 Centennial clausenamide and non-nuclear clausenamide was all over the see the plant operators, a group then sold to a group to Vietnam.

张东立承包的土地肥沃，且水份充足，十分适宜培育苗木，培育有80多万株优质的沉香苗。10多万株团花树和20多万株鸡心黄皮和无核黄皮，被各地的种植户看中，一批接一批地销往越南。

There is a close relationship between monoamines and learning and memory. NE and dopamine are believed to have a role in facilitation of memory. For this, an observation of clausenamide on monoamines and their metabolites as well as monoamine oxidase B activity was carried out.

目前认为脑内单胺类递质的变化与学习记忆密切相关，其中DA，NE的增加有助于学习记忆的形成，为了探讨黄皮酰胺的促智作用机制，我们首先研究了黄皮酰胺对小鼠脑内单胺类递质及其代谢产物和单胺氧化酶的影响。

Clausenamide had no obvious effect on monoamine oxidase B activity using HPLC-UV detector, indicating that increment of monoamines may involves another mechanism of action.

体外使用HPLC紫外检测法测单胺氧化酶B发现，黄皮酰胺对单胺氧化酶B无明显影响，提示黄皮酰胺增加单胺类递质并非由于抑制单胺氧化酶B引起。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
