Abstract:
Aim To prepare and qualitatively control the water extracts bioactive compounds (Danshen Gubao Ⅱ) from Danshen(Salvia miltiorrhiza) and to evaluate the effects of Danshen Gubao Ⅱ on osteoblast in vitro.Methods Danshen Gubao Ⅱ was extracted from salvia miltiorrhiza with a diluted hydrochloric acid method. The HPLC was used to determine the amounts of the bioactive compounds.PNPP methods were developed for the estimation of pharmacodynamic action by testing osteoblast activity (ALP expression).Results Compared Danshen Gubao Ⅱ with the ordinary water extract of salvia miltiorrhiza(DUAE Ⅰ), the amount of danshensu (main compound of salvia miltiorrhiza) was elevated to 3.28 times,11.50?0.52 mg?g-1, the amount of salvianolic acid B was reduced 1.46 times,16.40?1.22 mg?g-1,and each of their content was 1%～1.5%,the amount of protocatechualdehyde was elevated to 1.46 times,0.233?0.02 mg?g-1. The activity of Danshen Gubao Ⅱ on osteoblast was stronger than that of DUAE Ⅰ, 0.25 mg?L-1 of Danshen Gubao Ⅱ elevated 52%?10% osteoblast ALP expression,1.0 mg?L-1 of DUAE I elevated 5.5%?0.3% osteoblast ALP expression, and the results indicated that Danshen Gubao Ⅱ had more capacity on the osteoblast.Conclusions Danshensu, salvianolic acid B, protocatechualdehyde were stabilized in contents from Danshen Gubao Ⅱ, which could be qualitatively controlled.Danshen Gubao Ⅱ had good effect on osteoblast, which provided new data for the research of salvia miltiorrhiza's anti-osteoporosis preparation.
