摘要 | Traditional Chinese medicine is important for discovery of drug precursors. However, information about trace chemical composition of them is very limited due to the lack of appropriate enrichment and chromatographic purification methods In our work, A. kansuensis was taken as an example, a novel two-dimensional reversed-phase/hydrophilic interaction liquid chromatography coupled with UniElut C18AEX solid-phase extraction re enrichment method based on anti-inflammatory bioactivity-guided assay was developed for gathering and purifying trace beta-carboline alkaloids with high purity from the ethyl acetate extract of A. kansuensis. Extraction with ethyl acetate as the first enrichment method, then, a UniElut C18AEX column was employed to re-enrich trace fraction which was hardly detected by diode array detector during high performance liquid chromatography analysis, eighteen grams of UniElut C18AFX was used as sorbent material to pack a 60 mL pipette tip for the extraction of beta-carboline alkaloids from 100 mL of ethyl acetate sample. The whole extraction process was finished in 10 min, and the volume of eluent used was only 120 mL. The enriching fraction (100 mg) was used for the following two-dimensional purification. First-dimensional preparation was carried on a RP-Megress-C18 prep column, and four anti-inflammatory fractions were obtained from the 100 mg re-enriching sample with a recovery of 66.9%. A HILIC-XAmide prep column was selected for the second dimensional preparation. Finally, two pair of analogue beta-carboline alkaloids and one other beta-carboline alkaloid were purified from A. kansuensis. The purity of the isolated compounds was >> > 98%, which indicated that the method was efficient to re-enrich and manufacture single trace beta-carboline alkaloids with high purity from A. kansuensis. Additionally, this method showed great potential to serve as a good example for the purification and enrichment of analogue structure anti-inflammation carboline alkaloids from other plant materials. |
