Methods The compounds were isolated by silica gel, ODS, and macroporous resin column chromatography and their structures were determined by means of spectral analysis. 方法利用正相、反相硅膠柱和大孔樹(shù)脂柱色譜分離，并通過(guò)波譜技術(shù)進(jìn)行結(jié)構(gòu)鑒定。
Retention behavior of alkali metals, ammonium ion and alkyl amines on a sulfonic cation-exchange resin column with organic acid and inorganic acid as eluent was studied. 系統(tǒng)研究了堿金屬、銨離子和烷基胺在磺酸型陽(yáng)離子交換樹(shù)脂柱上以有機(jī)酸和無(wú)機(jī)酸為淋洗液的保留行為。
The crenulatin was extracted with water, and then separated with macroporous resin column, and analyzed with GC-MS. 樣品中的大花紅天素經(jīng)水提取，大孔樹(shù)脂柱凈化、分離。
