Establishment of Quantitatively Analytical Methods for the Determination of Aroma Components in Edib

A 5-cm-long polymer-based chromatographic monolith was fabricated and used as the stationary phase for high-performance liquid chromatography to quantitatively determine six aroma compounds in edible spices, namely, anethole from star anise, trans-cinnamaldehyde from cinnamon, hydroxy-alpha-sanshool from zanthoxylum, as well as 6-gingerol, 8-gingerol, and 10-gingerol from ginger.
Simple quantitative analytical methods for the determination of alkaloids from medicinal and edible

A polymer-based chromatographic monolithic column was prepared via in-situ radical polymerization using tetrahydrofurfuryl methacrylate as the monomer.
A rapid method for on-line solid-phase extraction and determination of dioscin in human plasma using

A phenyl-based polymer monolithic column was prepared via free radical polymerization in a stainless steel column with the size of 4.6 mm i.d. × 50 mm, using ethylene glycol phenyl ether acrylate as the monomer. The resulting monolithic column shows high porosity of 73.42% and relative uniform pore structure, as characterized by mercury porosimetry and scanning electron microscopy, respectively.
Fabrication of a cycloalkyl-monolith for on-line solid-phase

A cycloalkyl-based polymer monolithic column for solid-phase extraction was prepared via radical polymerization using cyclohexyl methacrylate as the monomer.

花椒中麻味物質(zhì)的分離與鑒定--麥德生生產(chǎn)研發(fā)部
成都麥德生科技有限公司于2018年首次從四川花椒中提取分離，由于山椒素類(lèi)單體的不穩(wěn)定性經(jīng)過(guò)幾次產(chǎn)品工藝的改進(jìn)，現(xiàn)在能穩(wěn)定的提供純度達(dá)到98%（HPLC-DAD）以上高純度單體。公司立足于花椒項(xiàng)目的研發(fā)，花椒品種的篩選，經(jīng)過(guò)3年時(shí)間從花椒（青...
某藥材乙酸乙酯部分的定制分離
受某中醫(yī)藥大學(xué)老師的委托，分離老師提供的藥材乙酸乙酯部位的化合物，化合物含量極低。通過(guò)多種分離純化手段，在2個(gè)月時(shí)間內(nèi)（近期圓滿(mǎn)收尾結(jié)束），總共分離出26個(gè)化合物，大部分純度在98%以上。公司的純化分離技術(shù)和專(zhuān)業(yè)受到老師肯定和贊揚(yáng)。
