| titleOfInvention | Method of obtaining and separating rosmarinic acid, apigenin and luteolin from elsholtzia haichowensis |
| abstract | The invention discloses a method of obtaining and separating rosmarinic acid, apigenin and luteolin from elsholtzia haichowensis. The method of obtaining and separating the rosmarinic acid, the apigenin and the luteolin from the elsholtzia haichowensis includes the following steps: (1) ethanol digestion: drying and grinding the obtained flowering branches and leaves of the elsholtzia haichowensis in the blooming period, and obtaining brownish black extractum through digestion and extraction; (2) conducting coarse separation of macroporous resin of brownish black extractum and obtaining yellowish-brown extractum through concentration; (3) conducting separation of polyamide columns of the brownish black extractum, and respectively obtaining extractum A, extractum B and extractum C; (4) respectively conducting chromatographic purification refining of the extractum A, the extractum B and the extractum C, and obtaining the the rosmarinic acid, the apigenin and the luteolin correspondingly. The method of obtaining and separating the rosmarinic acid, the apigenin and the luteolin from the elsholtzia haichowensis can obtain highly purified rosmarinic acid, apigenin and luteolin. |
