[Effects of plant growth regulator uniconazole on plant morphology and biomass allocation of Salvia miltiorrhiza].

In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray.

[Influence of different original processing methods on quality of Salvia Miltiorrhizae Radix et Rhizoma from Shandong].

In this paper the contents of rosmarinic acid, salvianolic acid B, crytotanshinone, tanshinone II(A) in samples of different original processed Salvia Miltiorrhizae Radix et Rhizoma were determined by HPLC. Different processing methods have varied influences on four active ingredients in Salvia Miltiorrhizae Radix et Rhizoma. Sun-drying reduced the content of crytotanshinone, tanshi-none II(A) and rosmarinic acid, integralsamples were better than those cut into segments.

Distribution patterns of the contents of five active components in taproot and stolon of Glycyrrhiza uralensis.

Wild or cultivated Glycyrrhiza uralensis FISCHER (G. uralensis) are the main source of licorice, and they contain the similar compounds, such as the triterpenoid saponins and flavonoids, but above two kinds of the components contents are low level in the cultivated licorice. To produce the high quality cultivated licorices, researchers studied the affecting factors about the compounds producing in the plant of licorice, and then found that the growth years, genetic differences and water deficit are all the important factors.
