ABSTRACT

Artemisiae Argyi Folium is commonly used in clinical practice. Artemisiae Verlotori Folium, the dried leaves of Artemisia verlotorum, is often used as a folk substitute for Artemisiae Argyi Folium in Lingnan area. In this study, gas chromatography-triple quadrupole mass spectrometry(GC-MS) was used to detect the volatile oil components of 27 samples of Artemisiae Verlotori Folium and 13 samples of Artemisiae Argyi Folium, and the volatile components were compared between the two species. The internal standard method was combined with multi-reaction monitoring mode(MRM) to determine the content of six major volatile components. Hierarchical clustering analysis(HCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were carried out for the content data. The results showed that the Artemisiae Argyi Folium samples had higher content and more abundant volatile oils than the Artemisiae Verlotori Folium samples. Artemisiae Argyi Folium mainly had the components with lower boiling points, while Artemisiae Verlotori Folium mainly had the components with higher boiling points. Terpenoids were the main volatile components in Artemisiae Verlotori Folium(mainly sesquiterpenoids) and Artemisiae Argyi Folium(monoterpenoids). In addition, Artemisiae Argyi Folium had higher content of oxygen-containing derivatives than Artemisiae Verlotori Folium. Furthermore, the stoichiometric analysis showed that the two species could be distinguished by both HCA and OPLS-DA, indicating that the volatile components of the two were significantly different. This study can provide a scientific basis for the quality evaluation and data support for the local rational application of Artemisiae Verlotori Folium in Lingnan.

ABSTRACT

This study aims to compare the chemical constituents in 24 batches of Artemisiae Argyi Folium samples collected from three different Dao-di producing areas(Anguo in Hebei, Nanyang in Henan, and Qichun in Hubei). An ultra-performance liquid chromatography(UPLC) method was established to determine the content of 13 nonvolatile components, and headspace-gas chromatography-mass spectrometry(HS-GC-MS) was employed for qualitative analysis and comparison of the volatile components. The content of phenolic acids in Artemisiae Argyi Folium was higher than that of flavonoids, and the content of nonvolatile components showed no significant differences among the samples from the three Dao-di producing areas. A total of 40 volatile components were identified, and the relative content of volatile components in Artemisiae Argyi Folium was significantly different among the samples from different Dao-di producing areas. The principal component analysis and partial least squares discriminant analysis identified 8 volatile components as the potential markers for discrimination of Artemisiae Argyi Folium samples from different Dao-di producing areas. This study revealed the differences in the chemical composition of Artemisiae Argyi Folium samples from three different Dao-di producing areas, providing analytical methods and a scientific basis for the discrimination and quality evaluation of Artemisia Argyi Folium in different Dao-di producing areas.

ABSTRACT

This study is based on ultra-high-performance liquid chromatography(UPLC), gas chromatography-mass spectrometry(GC-MS), and network pharmacology methods to analyze and predict potential quality markers(Q-markers) of Artemisiae Argyi Folium. First, UPLC and GC-MS techniques were used to analyze the content of 12 non-volatile components and 8 volatile components in the leaves of 33 Artemisia argyi germplasm resources as candidate Q-markers. Subsequently, network pharmacology was employed to construct a "component-target-pathway-efficacy" network to screen out core Q-markers, and the biological activity of the markers was validated using molecular docking. Finally, cluster analysis and principal component analysis were performed on the content of Q-markers in the 33 A. argyi germplasm resources. The results showed that 18 candidate components, 60 targets, and 185 relationships were identified, which were associated with 72 pathways related to the treatment of 11 diseases and exhibited 5 other effects. Based on the combination of freedom and component specificity, six components, including eupatilin, cineole, β-caryophyllene, dinatin, jaceosidin, and caryophyllene oxide were selected as potential Q-markers for Artemisiae Argyi Folium. According to the content of these six markers, cluster analysis divided the 33 A. argyi germplasm resources into three groups, and principal component analysis identified S14 as having the highest overall quality. This study provides a reference for exploring Q-markers of Artemisiae Argyi Folium, establishing a quality evaluation system, further studying its pharmacological mechanisms, and breeding new varieties.

ABSTRACT

Objective:To explore the effect of different proportions of organic fertilizer and chemical fertilizer on the agronomic traits, yield and quality of Artemisiae Argyi Folium in Qichun county, and provide a theoretical basis for scientific fertilization of its planting. Method:Field plot experiment was carried out to set up 5 treatment methods with different proportions of organic fertilizers and chemical fertilizers[OM<sub>0</sub> (no combined application of biological organic fertilizer), OM<sub>17</sub> (combined application of 17% biological organic fertilizer), OM<sub>33</sub> (combined application of 33% biological organic fertilizer), OM<sub>67</sub> (combined application of 67% biological organic fertilizer), OM<sub>100</sub> (combined application of 100% biological organic fertilizer)]. The effects of different treatment methods on the agronomic characters, leaf yield, output rate of moxa, volatile oil content, flavonoid and phenolic acid contents and mineral element contents of Artemisiae Argyi Folium in Qichun county were determined. Result:With the increase of the proportion of organic fertilizer in application, the seedling number per unit area, plant height, stem diameter, leaf number, leaf width, leaf length, height of dead leaves and leaf yield of Artemisiae Argyi Folium were increased at first and then decreased. Among them, the yield of Artemisiae Argyi Folium in OM<sub>33</sub> treatment was 61.37% higher than that in OM<sub>0</sub> treatment. With the increase of the proportion of organic fertilizer, the output rate of moxa of Artemisiae Argyi Folium showed continuously increasing trend, contents of volatile oil and volatile components (eucalyptol, <italic>α</italic>-thujone, borneol, camphor and caryophyllene oxide) increased at first and then decreased, while the contents of <italic>α</italic>-caryophyllene and <italic>β</italic>-syringene decreased gradually, the contents of phenolic acids (neochlorogenic acid, chlorogenic acid, isochlorogenic acid B, A and C) increased at first and then decreased, while the contents of flavonoids (jaceosidin and eupatilin) increased continuously, and the contents of mineral elements (Ca, Cu and Zn) continued to increase, but the content of K decreased significantly at the high proportion of organic fertilizer. After treated with principal component analysis (PCA), it was found that OM<sub>17</sub> treatment had the highest quality, while OM<sub>100</sub> and OM<sub>0</sub> treatment had low quality. Conclusion:Based on comprehensive analysis of agronomic traits, yield and quality indexes of Artemisiae Argyi Folium in Qichun county, it is suggested that 17%-33% proportion of organic fertilizer should be used in its production, in order to improve the quality and efficiency of Artemisiae Argyi Folium industry in Qichun county.

ABSTRACT

The study aims to qualitatively and quantitatively analyze phenolic acids and flavonoids in Artemisiae Argyi Folium cultivated in Qichun(Qiai) for the quality control of this genuine regional herbs. UPLC-LTQ-Orbitrap-MS was used for rapid separation and structural identification of the constituents. Samples were separated on an UPLC column(2. 1 mm×100 mm,1. 8 μm) by gradient elution using 0. 1% formic acid and acetonitrile as mobile phases at a flow rate of 0. 4 m L·min-1. By UPLC-LTQ-Orbitrap-MS,16 compounds including phenolic acids and flavonoids were identified by comparison with reference standards or literature data. For quantitative analysis,12 identified compounds were simultaneously determined by UPLC-DAD at wavelengths of 330 nm. The method was validated with respect to linearity,precision,repeatability,stability and recovery. The contents of these compounds were found to differ significantly between the samples from Qichun and other areas. This strategy was novel,effective and straightforward,which provided a potential approach for holistic quality control of Qiai.

ABSTRACT

Artemisiae Argyi Folium, the dried leaves of Artemisia argyi, has been widely used in traditional Chinese and folk medicines for treatment of hemorrhage, pain, and skin itch. Phytochemical studies indicated that volatile oil, organic acid and flavonoids were the main bioactive components in Artemisiae Argyi Folium. Compared to the volatile compounds, the research of nonvolatile compounds in Artemisiae Argyi Folium are limited. In the present study, an accurate and reliable fingerprint approach was developed using HPLC for quality control of Artemisiae Argyi Folium. A total of 10 common peaks were marked,and the similarity of all the Artemisiae Argyi Folium samples was above 0.940. The established fingerprint method could be used for quality control of Artemisiae Argyi Folium. Furthermore, an HPLC method was applied for simultaneous determination of seven bioactive compounds including five organic acids and two flavonoids in Artemisiae Argyi Folium and Artemisiae Lavandulaefoliae Folium samples. Moreover, chemometrics methods such as hierarchical clustering analysis and principal component analysis were performed to compare and discriminate the Artemisiae Argyi Folium and Artemisiae Lavandulaefoliae Folium based on the quantitative data of analytes. The results indicated that simultaneous quantification of multicomponents coupled with chemometrics analysis could be a well-acceptable strategy to identify and evaluate the quality of Artemisiae Argyi Folium.
