A Dominant Gene for Male Sterility in Salvia miltiorrhiza Bunge
A natural male sterile mutant of Salvia miltiorrhiza (Labiatae, Sh-B) was found during field survey in 2002. Our objective was to analyze its genetic mechanism for producing F1 hybrid seeds and to develop a molecular marker linked to male sterile gene for selection of a hybrid parent line. The segregation ratios of male sterile plants to fertile plants in the progenies of both testcross and bac...
متن کاملOptimization of Extraction Process for Polysaccharide in Salvia Miltiorrhiza Bunge Using Response Surface Methodology
This study was aimed to optimize the extraction process for Salvia miltiorrhiza Bunge polysaccharide using response surface methodology The results showed that four operating parameters including microwave power, microwave time and the particle size had notable effects on the polysaccharide extraction of Salvia miltiorrhiza Bunge. The effects could be ranked in decreasing order of importance as...
متن کاملInhibition of DNA Topoisomerase I by Dihydrotanshinone I, Components of a Medicinal Herb Salvia miltiorrhiza Bunge.
Dihydrotanshinone I induced topoisomerase I-mediated DNA cleavage in vitro as strongly as camptothecin, but topoisomerase II-mediated DNA cleavage was not affected. In a DNA relaxation assay using calf thymus DNA topoisomerase I and supercoiled pBR322 plasmid DNA, dihydrotanshinone I reduced topoisomerase I-mediated DNA relaxation in a dose-dependent manner. Heat treatment (65°C) of the reactio...
متن کاملAntibacterial activities of cryptotanshinone and dihydrotanshinone I from a medicinal herb, Salvia miltiorrhiza Bunge.
Cryptotanshinone and dihydrotanshinone I, constituents of a medicinal plant, Salvia miltiorrhiza Bunge, had antibacterial activity against a broad range of Gram positive bacteria. These compounds generated superoxide radicals in Bacillus subtilis lysates. A recombination-deficient mutant strain of B. subtilis was 2- to 8-fold more sensitive than a wild strain, and this hypersensitivity was redu...
متن کاملRadical Scavenging and Inhibition of Platelet Function by a Polyphenol- Rich Fraction from Salvia miltiorrhiza Bunge
A diet rich in polyphenols has previously been shown to be associated with a lower risk for cardiovascular disease. Specifically, inhibition of platelet hyperactivation by polyphenols decreases platelet-dependent thrombosis, reducing the risk for cardiovascular disease. However, whether polyphenols in Salvia miltiorrhiza Bunge (SMB) affect platelet functions has not been clearly determined. Her...
