introduction | vetzenin -2 is also called new zealand vitexin 2. at present, there are very few research reports on its pharmacological activities in China, but more attention has been paid abroad, and it has been reported that it has a variety of pharmacological activities. It includes effective anti-inflammatory effects on a variety of inflammatory cells and animal models, especially for vascular inflammation; anti-thrombotic and anti-platelet activity; treatment of diabetes; antispasmodic effect; combined with docetaxel Play the anti-prostate cancer effect and induce apoptosis and anti-oxidation of liver cancer HepG2 cells. |
preparation | the method for simultaneously separating xiafotin, vitening -2 and ecdysone includes taking about 5kg of dried pulverized lacquer grass and extracting it with 90%(V/V) ethanol three times, once a day, the extract was collected and combined, concentrated under reduced pressure until it was alcohol-free and slightly viscous, and the concentrated solution was dispersed with a small amount of water and then extracted with petroleum ether (60-90 ℃), ethyl acetate and n-butanol for 5-6 times, respectively. The extract of the n-butanol extraction site is divided into AB-8 macroporous resin twice, and the ratio of the sample to AB-8 macroporous resin is about 1:5 (left and right can float). After the sample is dissolved in hot water, the AB-8 macroporous resin resin column is added, and the ethanol solution of pure water, 30%, 50% and 70% is used for elution in sequence, TLC detection found that the target components to be separated (Shafeta glycoside, vicenin -2 and ecdysone) are mainly concentrated in the ethanol elution part of the 50%, and the ethanol elution part of the 50% is collected and concentrated under reduced pressure to obtain extract. The extract of the 50% ethanol elution part obtained above is dissolved with an eluent and then wet-applied to an ODS reversed-phase chromatography column. The ratio of the sample to the ODS filler is about 1:80 (which can float around), and methanol: water = 1:1.5 is used as the elution solvent for elution (the ratio of the elution agent can be adjusted according to the specific conditions of TLC on this basis). TLC detects and combines the same components until all the target components flow out, compound A (ecdysone), impurity-containing compound B (vicenin -2) and impurity-containing compound C (xiapotalin) were obtained. The impurity-containing compound B (vicenin -2) and the impurity-containing compound C (xiapotalin) were further separated and purified by silica gel column respectively, and the elution system was made of ethyl acetate-methanol-water, and the ratio was ethyl acetate: methanol: water ≈ 8:1:1 (which can be adjusted according to the specific conditions of TLC on this basis). TLC was detected and combined with the same components until all the target components flowed out, to obtain compound B (vicenin -2) and compound C (xiapotalin). |
