| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Preparative isolation and purification of six diterpenoids from the Chinese medicinal plant Salvia miltiorrhiza by high-speed counter-current chromatography.[Pubmed:11519796]
J Chromatogr A. 2001 Aug 3;925(1-2):109-14.
A high-speed counter-current chromatography (HSCCC) method was developed for the preparative separation and purification of six diterpenoids. dihydrotanshinone I, cryptotanshinone, methylenetanshiquinone, tanshinone I, tanshinone IIA and Danshenxinkun B from the Chinese medicinal plant Salvia miltiorrhiza Bunge. The crude diterpenoids were obtained by extraction with ethanol-n-hexane (1:1, v/v) from S. miltiorrhiza Bunge. Preparative HSCCC with the two-phase solvent systems A composed of n-hexane-ethanol-water (10:5.5:4.5, v/v) and B composed of n-hexane-ethanol-water (10:7:3, v/v) was successfully performed in a stepwise elution yielding six relatively pure diterpenoids from 300 mg of the crude extract in a single run. The purities of dihydrotanshinone I, cryptotanshinone, methylenetanshiquinone, tanshinone I, tanshinone IIA and Danshenxinkun B were 88.1, 98.8, 97.6, 93.5, 96.8 and 94.3%, respectively.
Danshenxinkun B is an antioxidative component of tanshen (Salvia miltiorhiza Bung) .
