Before use, the AB-8 macroporous resin was soaked in 95% ethanol for 24 h and washed several times using the deionized water.
Study on separation and purification of Geniste in the soybean residue using macroporous resin adsorption.
Improving catalytic performance of Burkholderia cepacia lipase immobilized on macroporous resin NKA.
pH ([degrees]C) Accurel MP 1000 100 40 -- macroporous resin NKA 84.
The highly polar antioxidants were firstly isolated and purified from Chirita longgangensis by combination of macroporous resin and HSCCC (Duan et al.
Application of high-speed counter-current chromatography combined with macroporous resin for rapid enrichment and separation of three anthraquinone glycosides and one stilbene glycoside from Rheum tanguticum.
Methods: Chemical constituents were extracted and purified by ethanol reflux extraction and chromatographic separation technology including D-101 Macroporous resin
, silica gel, Sephadex LH-20 and preparative thin-layer chromatography.
Crude extract of summer green tea obtained by hot water extraction was passed through columns of polyamide and NKA-II macroporous resin
respectively, resulting in tea polyphenols-enriched fraction (96.
The macroporous resins
NKA-11 was used for chromatography of the crude extract L The macroporous resin
NKA-11 is a kind of cross-linked polystyrene with polarity.
giganteum could significantly prolong the survival time of myocardial hypoxia mice, fractions eluted by 50% EtOH in NKA-9 type macroporous resin
could significantly prolong the survival time in myocardial hypoxia mice, but also to improve the biochemical indicators of myocardial ischemia mice, so extraction process using 60% EtOH should be a more reasonable extraction method, the eluted material with 50% EtOH in macroporous resin
should be the active friction.
The extract was concentrated under reduced pressure, and then dissolved in 30% ethanol to give 1 g/ml (crude medicine/volume) sample liquor, and then this liquor was passed through AB-8 macroporous resin
column with 1 time the volume which was comparable to the weight of macroporous resin
According to Bourelle, macroporous resins
are noted for their durable polymer structure which provides both osmotic strength and long-term chemical and thermal stability.
