Jul 23, 2021 · The experiment was carried out to screen macroporous resins, and D-101 was identified as the best resin for the crude triterpenoid acid enrichment of blackened jujube. Through static and dynamic experiments, the optimum process parameters of resin were obtained.

Jujube induces neurite outgrowth and neurothrophic factor expression via cAMP-dependent PKA signaling. Jujube possessed neuroprotection against oxidative stress via enhancing cellular Nrf2-dependent ARE-driven gene expressions.

Due to its “homology of medicine and food,” jujube is one of the traditional Chinese herbs that is extensively used in China. In addition, jujube has received much attention around the world for its excellent pharmacological effects and food value.

Jan 30, 2022 · Ultrasound enhanced the affinity between jujube peel flavonoids and MRs. The work explored the process of ultrasound-assisted adsorption/desorption to efficiently purify jujube peel flavonoids (JPFs) using macroporous resins (MRs). The impact of ultrasound power and temperature on the adsorption/desorption features of JPFs on MRs were studied.

Dec 1, 2015 · Results showed that LSA-900B resin exhibited an effective adsorbability of patulin in jujube juice, and the maximum adsorption quantity and removal rate were 5.31 μg/g and 73.78%, respectively.

Jul 23, 2021 · In order to investigate the purification process and antioxidant activity of triterpenic acids from blackened jujube, the macroporous resin was applied to purify the crude extract from blackened...

Scanning electron microscopy (SEM) analysis indicated that ultrasound treatment severely damaged the structural integrity of sour jujube leaves, which was more conducive to improving the SJL-TF yield. Then, polyamide resin chromatography was used to purify the crude SJL-TF extracts, increasing the SJL-TF purity by 3.2-fold to 74.58 ± 0.63 %.

Dec 1, 2015 · Results showed that LSA-900B resin exhibited an effective adsorbability of patulin in jujube juice, and the maximum adsorption quantity and removal rate were 5.31 μg/g and 73.78%, respectively.

Through the investigation of static adsorption and desorption of resins, the most suitable macroporous resin for the purification of jujube polysaccharides was selected and its dynamic adsorption and desorption behavior was studied.

The method of HPLC-PDA-ESI-MS n was simple and rapid for the identification of the flavonoids and saponins from Chinese jujube. Among them, seventeen compounds were reported for the first time. What’s more, D101 macroporous polystyrene resin was a good pretreatment method to obtain better separation and impurity removal effect.
