[Rapid detection of zearalenone in Coicis Semen based on ELISA].

Zearalenone(ZEN) is a toxic metabolite produced by Fusarium culmorum, F. graminearum, F. tricinctum, and other fungi, with estrogenic characteristics. Exposure to or ingestion of ZEN during pregnancy can cause reproductive dysfunction, miscarriage, stillbirth, and malformation, and seriously endanger human life and health. The detection methods for ZEN in the Chinese Pharmacopoeia(2020 edition) are liquid chromatography(LC) and liquid chromatography-mass spectrometry(LC-MS), and it is stipulated that ZEN should not exceed 500 µg in 1 000 g of Coicis Semen. Although these detection methods by instruments can achieve the qualitative and quantitative analysis of ZEN in Coicis Semen, their high detection cost and long periods hinder the rapid screening of a large number of samples in the field. In this study, the synthesized ZEN hapten was conjugated with bovine serum albumin(BSA) and ovalbumin(OVA) to obtain the complete ZEN antigen. By virtue of antibody preparation techniques, ZEN monoclonal antibody 4F6 was prepared, which showed 177.5%, 137.1%, and 109.7% cross-reactivity with ZEN structural analogs zearalanol, zearalenone, and α-zearalenol, respectively, and no cross-reactivity with other fungal toxins such as aflatoxin. Direct competitive enzyme-linked immunosorbent assay(dcELISA) based on ZEN monoclonal antibody 4F6 was developed for the determination of ZEN in Coicis Semen with an IC_(50) of 1.3 µg·L~(-1) and a detection range of 0.22-21.92 µg·L~(-1). The recoveries were 83.91%-105.3% and the RSD was 4.4%-8.0%. The established dcELISA method was used to determine the ZEN residuals in nine batches of Coicis Semen samples, and the results were validated by LC-MS. The correlation between the two detection methods was found to be 0.993 9, indicating that the established dcELISA could be used for the rapid qualitative and quantitative detection of ZEN residuals in Coicis Semen.

[Nature-effect transformation mechanism of mulberry leaves and silkworm droppings based on chemical composition analysis].

Starting with the relationship between mulberry leaves and silkworm droppings as food and metabolites, this study systematically compared the chemical components, screened out differential components, and quantitatively analyzed the main differential components based on ultra-high performance liquid chromatography with quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS) and UPLC-Q-TRAP-MS combined with principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA). Moreover, the in vitro enzymatic transformation of the representative differential components was studied. The results showed that(1) 95 components were identified from mulberry leaves and silkworm droppings, among which 27 components only exist in mulberry leaves and 8 components in silkworm droppings. The main differential components were flavonoid glycosides and chlorogenic acids.(2) Nineteen components with significant difference were quantitatively analyzed, and the components with significant differences and high content were neochlorogenic acid, chlorogenic acid, and rutin.(3) The crude protease in the mid-gut of silkworm significantly metabolized neochlorogenic acid and chlorogenic acid, which may be an important reason for the efficacy change in mulberry leaves and silkworm droppings. This study lays a scientific foundation for the development, utilization, and quality control of mulberry leaves and silkworm droppings. It provides references for clarifying the possible material basis and mechanism of the pungent-cool and dispersing nature of mulberry leaves transforming into the pungent-warm and dampness-resolving nature of silkworm droppings, and offers a new idea for the study of nature-effect transformation mechanism of traditional Chinese medicine.

[Dead heart of pith-decayed Scutellariae Radix: a study based on multi-omics].

Dead heart is an important trait of pith-decayed Scutellariae Radix. The purpose of this study was to clarify the scientific connotation of the dead heart using multi-omics. Metabolomics and transcriptomics combined with multivariate statistical analysis such as principal component analysis(PCA) and partial least squares discriminant analysis(PLS-DA) were used to systematically compare the differences in chemical composition and gene expression among phloem, outer xylem and near-dead xylem of pith-decayed Scutella-riae Radix. The results revealed significant differences in the contents of flavonoid glycosides and aglycones among the three parts. Compared with phloem and outer xylem, near-dead xylem had markedly lowered content of flavonoid glycosides(including baicalin, norwogonin-7-O-ß-D-glucuronide, oroxylin A-7-O-ß-D-glucuronide, and wogonoside) while markedly increased content of aglycones(including 3,5,7,2',6'-pentahydroxy dihydroflavone, baicalin, wogonin, and oroxylin A). The differentially expressed genes were mainly concentrated in KEGG pathways such as phenylpropanoid metabolism, flavonoid biosynthesis, ABC transporter, and plant MAPK signal transduction pathway. This study systematically elucidated the material basis of the dead heart of pith-decayed Scutellariae Radix with multiple growing years. Specifically, the content of flavonoid aglycones was significantly increased in the near-dead xylem, and the gene expression of metabolic pathways such as flavonoid glycoside hydrolysis, interxylary cork development and programmed apoptosis was significantly up-regulated. This study provided a theoretical basis for guiding the high-quality production of pith-decayed Scutellariae Radix.

[Development of a monoclonal antibody-based enzyme-linked immunosorbent assay for determination of vomitoxin (DON) in Coicis Semen].

Coicis Semen is a common bulk medicinal material used for both medicine and food, which has the effect of promoting diuresis, draining dampness, invigorating the spleen and checking diarrhea. It is derived from Coix lacryma-jobi var. ma-yuen of the family Poaceae, and is easily contaminated by fungi such as Fusarium graminearum and F. flavum due to climate reasons to produce vomitoxin. The guiding principles for determination of vomitoxin in Chinese medicinal materials in Chinese Pharmacopoeia are mainly HPLC and LC-MS, which have long detection period and are time-consuming and laborious, and thus cannot meet the requirements of on-site quality inspection of drugs. The complete antigen of vomitoxin-protein was obtained by chemical derivatization of vomitoxin. The monoclonal antibody against vomitoxin was prepared by classic monoclonal antibody preparation technology, and enzyme-linked immunosorbent assay(ELISA) method for detection of vomitoxin in Coicis Semen was established through methodological investigation. The IC_(50) based on the ELISA for vomitoxin in Coicis Semen was 3.88 µg·L~(-1), and the average recoveries and the RSD were 77.32%-93.73% and 4.6%-9.7%, respectively. With the established ELISA method, the vomitoxin residue in 14 batches of Coicis Semen samples were determined and validated by LC-MS, and the correlation between the two assays was found to be 0.997 8, indicating that the established ELISA method could be used for quantitative determination of vomitoxin residue in Coicis Semen and could achieve the rapid quantitative determination of the vomitoxin residue.

[Comparison of major chemical components in Puerariae Thomsonii Radix and Puerariae Lobatae Radix].

[Differences between male and female leaves of Schisandra sphenanthera: based on RNA-Seq].

Schisandra sphenanthera is dioecious and only the fruits of female plants can be used as medicine and food. It is of great significance for the cultivation and production of S. sphenanthera to explore the differences between male and female plants at the non-flowering stage and develop the identification markers at non-flowering or seedling stage. In this study, the transcriptome of male and female leaves of S. sphenanthera at the non-flowering stage was sequenced by Illumina high-throughput sequencing technology and analyzed based on bioinformatics. A total of 236 682 transcripts were assembled by Trinity software and 171 588 were chosen as unigenes. Finally, 1 525 differentially expressed genes(DEGs) were identified, with 458 up-regulated and 1 067 down-regulated in female lea-ves. The down-regulated genes mainly involve photosynthesis, photosynthesis-antenna protein, carbon fixation in photosynthetic or-ganisms, and other pathways. Real-time quantitative PCR(qPCR) identified two genes between male and female leaves and one of them was a HVA22-like gene related to floral organ development and abscisic acid(ABA). Enzyme linked immunosorbent assay(ELISA) was applied to determine the content of ABA, auxin, gibberellin, and zeatin riboside(ZR) in leaves of S. sphenanthera. The results showed that the content of ABA and ZR in male leaves was significantly higher than that in female leaves. The involvement of down-regulated genes in female leaves in the photosynthesis pathway and the significant differences in the content of endogenous hormones between male and female leaves lay a scientific basis for analyzing the factors affecting sex differentiation of S. sphenanthera.

[Expression analysis of transcription factor ERF gene family of Panax ginseng].

Ethylene responsive factor(ERF), one of the largest families of transcriptional factors in plants, plays a key role in se-condary metabolism of herbal plants. To analyze the expression of ERF family genes, the heat map clustering method was used by analyzing the ginseng transcriptomes of different parts and different growth years. The contents of ginsenosides Rg_1, Re and Rb_1 in various concentrations of MeJA-treated ginseng adventitious roots were determined by UPLC-MS/MS method. The expression of key genes of ginsenoside biosynthesis(DDS, CYP716A47, CYP716A53v2) and ERF family genes in MeJA-treated ginseng adventitious roots were determined by using real-time quantitative PCR. Pearson correlation was adopted to analyze the gene expression pattern of DDS, CYP716A47, CYP716A53v2 gene and ERF family. The results showed that the content of ginseng diol ginsenoside Rb_1 in ginseng adventitious roots treated with different concentrations of MeJA increased, and the content of ginseng triol ginsenoside Rg_1 and Re decreased. It is consistent with the increase of DDS and CYP716A47 expression and the decrease of CYP716A53v2 gene expression. The expression of ERF003, ERF118 and ERF012 genes was significantly positively correlated with CYP716A53v2, but negatively correlated with DDS. While the expression of ERF1B was significantly negatively correlated with CYP716A47.It is proved that ERF003, ERF118 and ERF012 were likely to inhibit the expression of DDS and promote the expression of CYP716A53v2, and ERF1B was likely to inhibit CYP716A47. This work could provide theoretical basis of ERF functional verification of regulating the biosynthesis of ginsenosides.

[Research actuality and quality-influencing factor of Epimedii Folium].

Epimedii Folium has a long history in China as a common traditional Chinese medicine. Key factors of Epimedii Folium quality were summarized based on ancient literatures, Chinese Pharmacopoeias and modern research in different period of history. The main reason for unqualified Epimedii Folium is unstable icariin. Therefore, it's suggested that: the precondition of the quality control of epimedium is to find the proper quality marker. It's suggested that the medicinal parts should be reverted to "dry whole plant overground" to solve Epimedium resource shortage problem. In addition, it is necessary to strengthen the standardized cultivation, so as to ensure germplasm, production area, and producing method to guarantee the quality of Epimedium Folium. In the drying method, it is recommended to change "dry in the sun or shade" to "dry", namely dry in the sun, shade or drier, in order to provide a new method to improve the quality control and quality standard of Epimedii Folium.
