Chek Hup Ipoh White coffee is famous for it's unique aroma,rich tastes and smoothness . It also has low level of sour element and bitterness .

在烘培过程中，白咖啡是不加焦糖低温烘培而成，制出来之咖啡豆味道浓郁、保存期较长、产品不易变酸，保留了咖啡原有的香味，同时去除了高温炭烤所产生的焦苦和酸涩味，香醇且不伤肠胃。

A high performance liquid chromatographic method was established for determination of caffeic acid contents in tetraploidy taraxacum officinale and diplontic taraxacum dissectum.

本文采用四倍体药蒲公英和二倍体多裂蒲公英为材料，通过HPLC法测定并比较两种蒲公英中咖啡酸的含量，以大力推广产量高，抗逆性强，药用活性成分高的优质多倍体蒲公英新品种。

Used the main eight kinds of phenolic acids with plant-defensive function as a control,and a high performance liquid chromatography to detected the leaves of corn that containing vanillic acid, caffeic acid, syringic acid and coumaric acid.

以植物中主要具有防御功能的8种酚酸作为对照，采用高效液相色谱法测得玉米叶片中主要含有香草酸、咖啡酸、丁香酸及香豆酸4种酚酸类化合物。

Through activating the synthesis of jasmonic acid itself,aboveground application of jasmonia acid could induce the expression of Bx1,Bx9,PAL,PR-1,MPI,FPS and TPS genes,increase DIMBOA content and decrease caffeic acid content in leaves;on the other hand,the systematic induction of gene expression of Bx6,Bx9、PAL and PR-2a,increase of contents of coumaric acid and caffeic acid,and decrease of syringic acid content in the roots were related with the activating of jasmonic acid synthesis in the aboveground.

茉莉酸处理地上部是通过激活茉莉酸自身合成来诱导叶片Bx1、Bx9、PAL、PR-1、MPI、FPS和TPS基因的表达、增加叶片丁布含量及降低咖啡酸含量的，同时系统诱导根系Bx6、Bx9、PAL和PR-2a基因表达、增加香豆酸和咖啡酸含量以及降低丁香酸含量则与激活地上部茉莉酸自身合成相关。
