Phytochemical Analysis, Antioxidant Activities In Vitro and In Vivo, and Theoretical Calculation of Different Extracts of .

has a long-standing history of use in traditional medicine for the treatment of tuberculosis diseases. However, the plant's therapeutic potential extends beyond this specific ailment. The present study aimed to investigate the antioxidant properties of and lay the groundwork for further research on its potential therapeutic applications.

Diversity and composition of the Panax ginseng rhizosphere microbiome in various cultivation modesand ages.

Background: Continuous cropping of ginseng (Panax ginseng Meyer) cultivated in farmland for an extended period gives rise to soil-borne disease. The change in soil microbial composition is a major cause of soil-borne diseases and an obstacle to continuous cropping. The impact of cultivation modes and ages on the diversity and composition of the P.

[Research progress on metabolism and pharmacological activities of several iridoid glycosides].

As a large category of natural products widely present in traditional Chinese medicine, iridoid glycosides have multiple pharmacological activities. Recent researches suggest that iridoid glycosides mainly exist in the forms of original form, aglycone and a series of their Ⅰ and Ⅱ metabolites under the biotransformation effect, and their metabolites have been proved to have multiple pharmacological activities. The research progress on metabolism and metabolite activities of several iridoid glycosides would be reviewed in this article, to provide a theoretical basis for the further development and utilization of iridoid compounds and their metabolites.

[Experimental investigation on micro-hollow cathode sustained discharge].

Based on micro-hollow cathode discharge (MHCD) as a plasma cathode, a second anode was added to the device for obtaining large volume and uniform plasma at high pressure. The discharge producing condition of MCSD was investigated in the experiments. And the rotational structures of the N2 first positive bands were analyzed with traces of nitrogen added in argon for the measurements of the gas temperature in the MCSD plume.

[Optical emission spectroscopy for the characteristic parameters measurement of argon microhollow cathode discharge].

In order to measure the basic plasma parameters, well understand the mechanism of microhollow cathode discharge (MHCD), the rotational structures of the N2 first positive bands (B3 pi(g)A3+u) were analyzed with traces of nitrogen added in argon for the measurement of the gas temperature, and the Stark broadening of Hbeta lines was analyzed for the determination of the electron density. The experimental results show that the gas temperature increases with the increasing pressure and the current and can reach 700 K in the stable glow region. The electron density is in the order of 10(14)-10(15) cm(-3).

Late-bolting transgenic Chinese cabbage obtained by RNA interference technique.

LEAFY (LFY) gene plays an important role in determining plant flowering mainly by controlling the timing of phase transition. Constitutive under-expression of LFY in Arabidopsis resulted in the formation of a late-flowering and highly branching phenotype. In this paper, an RNAi approach was used in down-regulated LFY gene expression to delay Chinese cabbage (Brassica rapa L.

Phosphorus accumulation by bacteria isolated from a continuous-flow two-sludge system.

In this article, polyphosphate-accumulating organisms (PAOs) from a lab-scale continuous-flow two-sludge system was isolated and identified, the different phosphorus accumulation characteristics of the isolates under anoxic and aerobic conditions were investigated. Two kinds of PAOs were both found in the anoxic zones of the two-sludge system, one of them utilized only oxygen as electron acceptor, and the other one utilized either nitrate or oxygen as electron acceptor. Of the total eight isolates, five isolates were capable of utilizing both nitrate and oxygen as electron acceptors to uptake phosphorus to some extent.
