The experiment was conducted to evaluate the effects of five rubber seed oil (RSO) levels (0, 1%, 2%, 4%, and 6%) on hens laying performance, egg quality, and yolks fatty acid composition and cholesterol contents. Three hundred and sixty 30-week-old Lohmann Brown laying hens were allotted to 5 groups. The results showed that the egg production was increased in 4% RSO group (P < 0.05), but egg quality parameters and the contents of dry matter, lipid, and protein in yolks were not influenced among treatments (P > 0.05). Yolk cholesterol contents were reduced in RSO supplemental groups (P < 0.05). The concentration of total n-3 PUFA in yolks increased gradually while the ratio of n-6/n-3 decreased gradually with increasing dietary RSO levels (P < 0.001). In conclusion, dietary RSO supplementation increased yolk n-3 PUFA levels, improved yolk color, and reduced yolk cholesterol contents without negative influence on laying performance parameters.

In recent years, the fingerprint of high performance liquid chromatography has been extensively applied in the identification and quality control of traditional Chinese medicine. It can be a potential protocol for assessing the authenticity, stability and consistency of traditional Chinese medicine and guaranteeing the expected biological activity. In this paper, a method using high‐performance liquid chromatography to identify and control the quality of the extract of Taraxacum mongolicum Hand.‐Mazz. (TME) was established. With this method, the correlation coefficients of the similarity of 10 batches were ≥ 0.994. The TME displayed steady proliferative effect in Lactobacillus plantarum. In brief, this study successfully built a reliable, simple and efficient method to control and confirm the quality and the stability of biological activity of the TME.

In this work of quercetin's anti-proliferation action on A. flavus, we revealed that quercetin can effectively hamper the proliferation of A. flavus in dose-effect and time-effect relationships. We tested whether quercetin induced apoptosis in A. flavus via various detection methods, such as phosphatidylserine externalization and Hoechst 33342 staining. The results showed that quercetin had no effect on phosphatidylserine externalization and cell nucleus in A. flavus. Simultaneously, quercetin reduced the levels of reactive oxygen species (ROS). For a better understanding of the molecular mechanism of the A. flavus response to quercetin, the RNA-Seq was used to explore the transcriptomic profiles of A. flavus. According to transcriptome sequencing data, quercetin inhibits the proliferation and aflatoxin biosynthesis by regulating the expression of development-related genes and aflatoxin production-related genes. These results will provide some theoretical basis for quercetin as an anti-mildew agent resource.

Similarity evaluation of complicated chromatographic profiles is a potential proticol for the identification and quality control of herbal medicinal products to ensure their biological activity. In this work, a high-performance liquid chromatography method was established for controlling the batch quality of the extract from Portulaca oleracea L. By using this method, the coefficients of correlation of the similarity of 10 batches extract of Portulaca oleracea L. were≥0.97. The 10 batch extracts from Portulaca oleracea L. possessed stable antiproliferative activity in Aspergillus flavus. The antiproliferative activity stability is correlated with the quality stability of the extract from Portulaca oleracea L. Therefore, the present study successfully set up a sensitive and efficient method which might be used to guarantee stable biological activity of the extract from Portulaca oleracea L.

Up till now, studies have not been conducted on how the combination of Quercetin (Q), Aconitine (A) and apoptosis induction affects human cervical carcinoma HeLa cells. The result of our findings shows that the combination of Q and A (QA) is capable of synergistically inhibiting the proliferation of HeLa cells in a number of concentrations. QA synergistically inhibits the proliferation of MDR1 gene in the HeLa cells. It is concluded based on our result that QA induces apoptosis and ER stress just as QA-induced ER stress pathway may mediate apoptosis by upregulating mRNA expression levels of eIF2α, ATF4, IRE1, XBP1, ATF6, PERK and CHOP in the HeLa cells. The up-regulating of mRNA expression level of GRP78 and activation of UPR are a molecular basis of QA-induced ER stress.

Similarity evaluation of complicated chromatographic profiles is a potential instrument for the identification and quality control of herbal medicinal products to ensure the prospective biological activity. The present study was implemented to evaluate the quality of Sonchus brachyotus DC. sampled using high-performance liquid chromatography (HPLC) fingerprinting coupled with a suite of chemometrics methods. By this means, the coefficients of correlation of similarity of 10 batches extract of S. brachyotus DC. were >0.98. The 10 batches extract of Sonchus brachyotus DC. showed stable antioxidant capacity in vitro. The results of total antioxidant capacity were in accordance and completed well for the quality evaluation of Sonchus brachyotus DC. Thus, HPLC fingerprinting coupled with chemometrics techniques provides a greatly flexible and dependable method for the quality assessment of the extract of Sonchus brachyotus DC.

Portulaca oleracea L. (P. oleracea) has been used as a Chinese herbal medicine for the treatment of antipyretic, anti-scorbutic, antiseptic, antispasmodic, diuretic, anthelmintic, and urinary disorders. However, pharmacological studies are necessary to provide a scientific basis to substantiate its effectiveness. In this study, the antimicrobial effect and its mechanism of the flavonoids extract from P. oleracea. (POFE) were investigated. The antibacterial effects of POFE were tested on Enterobacter cloacae, Klebsiella pneumonia, Escherichia coli, Staphylococcus aureus, Salmonella enterica and Micrococcus luteus, and the results showed that some bacteria, especially Staphylococcus aureus, were sensitive to POFE. At the tested concentrations, POFE-treated cells displayed various apoptotic markers, such as reactive oxygen species (ROS) accumulation, membrane depolarisation, phosphatidylserine (PS) exposure, DNA fragmentation, and caspase-like protein, in a dose-dependently manner. Based on these data, we concluded that POFE entered the cytoplasm through the membrane pores of Staphylococcus aureus, and subsequently, two parallel reactions took place, namely increase in the level of ROS and DNA fragmentation, which caused cell death.
