roseus nplooj nrog cov kua qaub aqueous; nce pH thiab rho tawm ib qho alkaloid sib tov nrog cov kuab tshuaj organic; chromatographing ib tug tov ntawm alkaloid sib tov tshaj dextran thiab silica gel kab kom tau vinblastine uas muaj feem rau kev rho tawm.
Vinblastine ua li cas?
Cov tshuaj sib txawv tuaj yeem cuam tshuam rau lwm qhov ntawm lub cev. Vinblastine belongs rau ib chav kawm ntawm cov tshuaj chemotherapy hu ua alkaloids. Cog alkaloids yog tsim los ntawm cov nroj tsuag. Cov vinca alkaloids yog ua los ntawm cov nroj tsuag periwinkle(catharanthus rosea).
