Bacillus radicibacter sp. nov., a new bacterium isolated from root nodule of Oxytropis ochrocephala Bunge.
A Gram-positive, facultative anaerobic, rod-shaped, and endospore-forming strain, designated 53-2(T) was isolated from the root nodule of Oxytropis ochrocephala Bunge growing on Qilian mountain, China. The strain can grow at pH 7.0-8.0, 10-50 °C and tolerate up to 11% NaCl. Optimal growth occurred at pH 7.2 and 37 °C. The result of BLASTn search based on 16S rRNA gene sequence revealed that str...
متن کاملA NEW ALKALOID FROM FLOWERS OF ERYTHRINA STRICTA
The alkaloids present in the flowers of Erythrina stricta have been isolated and characterized by spectroscopic methods. A new alkaloid 11-acetyl erysotrine has been isolated and its structure established by spectral studies (UV, IR, 1H NMR and HRMS).
متن کاملAnti-hypoxia effects of the ethanol extract of Oxytropis ochrocephala
Oxytropis ochrocephala is one of the most extensively used herbs in traditional Tibetan folk medicine to clear heat through detumescence, strengthen the body, and improve immune system. However, research studies examining its medicinal value are limited. By conducting experiments using animal models (mice) in airtight space at ambient and reduced pressure, as well as sodium nitrite exposure, th...
متن کاملThe effect of alkaloid from Oxytropis ochrocephala on growth inhibition and expression of PCNA and p53 in mice bearing H22 Hepatocellular Carcinoma.
To study the antitumor activity of alkaloid extracted from Oxytropis ochrocephala and its possible mechanism, we observed the effect of alkaloid on tumor weight and expression of PCNA and p53 in mice bearing H(22) hepatocellular carcinoma by means of immunohistochemistry SP method. After treatment with alkaloid from Oxytropis ochrocephala, the results showed that alkaloid administration (25 and...
متن کاملSelection of appropriate reference genes for quantitative real-time PCR in Oxytropis ochrocephala Bunge using transcriptome datasets under abiotic stress treatments
BACKGROUND Oxytropis ochrocephala Bunge, an indigenous locoweed species in China, poses great threats to livestock on grasslands. There is a need for further genetic study in the plants per se, for understanding the basis of its acclimation mechanism in various unfavorable environmental conditions and to implement effective control measures. Quantitative real-time reverse transcription-polymera...
