ABSTRACT

We identified and analyzed the components and chemical constituents of hawthorn leaves of Crataegus pinnatifida Bge. (wild) and C. pinnatifida Bge. var major N. E. Br (cultivated) by using ultra high-performance liquid chromatography and quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF/MSE) combined with UNIFI data analysis platform and multivariate statistics. Fifty-eight chemical compounds were identified, including organic acids, flavonoids, triterpenoic acids, monoterpenes and sesquiterpenoids; among them, terpenoid content was the most abundant. Principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) were used to identify the differential components of hawthorn leaves from two sources. The results show that there are differences in the chemical compositions of the two sources, including 24 flavonoids and terpenoids (including monoterpenoids, sesquiterpenoids and triterpenoid acids). The types of flavonoids (such as rutin, vitexin-2''-O-rhamnoside, isovitexin-2''-O-rhamnoside, hyperoside, quercetin-3-O-β-D-glucoside) and terpenoids (crataegolic acid, corosolic acid and ursolic acid) in C. pinnatifida were more varied than those found in C. pinnatifida Bge. var major N. E. Br, and their contents were relatively higher. This study provides a comprehensively analysis of the different chemical components of hawthorn leaves from two sources listed in the Chinese Pharmacopoeia, and provides a basis for the selection of raw materials and the potential development and utilization of hawthorn leaves.

ABSTRACT

Perilla frutescens is a traditional medicinal and edible plant widely distributed in China and enjoys an extensive usage. P. frutescens contains multiple essential oils, which are composed of monoterpenes, sesquiterpenes, and their oxygen-containing derivatives. Compared with other parts of P. frutescens, Perillae Folium produce more oils, with volatile oils as the main constituents. There are many active substances in the volatile oils from Perillae Folium, mainly including perillaldehyde, perillaketone, perillaalcohol, D-limonene, β-caryophylene, etc. Such factors as germplasm, growth environment, extraction method, cultivation time, and harvest period all can trigger changes in volatile oil constituents and content from Perillae Folium. The volatile oils from Perillae Folium have diverse pharmacological effects like anti-oxidation, anti-bacteria, anti-inflammation, vasodilation, anti-tumor, and anti-depression, implying its high clinical application value. However, the chemical constituents in volatile oils from Perillae Folium are complex and unstable and their pharmacological activities are affected by many factors, so the safety and effectiveness of clinical medication fail to be guaranteed, which may has impeded the rational and effective use of these volatile oils. Many scholars in China and abroad have conducted a lot of research on the volatile oils from Perillae Folium, but there is currently no systematic and comprehensive research report on the chemical constituents of volatile oils from Perillae Folium and their pharmacological effects. This paper reviewed the relevant domestic and foreign literature, analyzed the development status of volatile oils from Perillae Folium, and summarized their extraction process, chemical constituents, and pharmacological actions, aiming to provide a reference for their further development, clinical application, and risk assessment.

The structures of the obtained compounds were identified by spectroscopic methods of nuclear magnetic resonance (NMR), mass spectroscopy (MS) and infrared spectroscopy (IR). Meanwhile, some of these compounds isolated from Violae Herba were carried on the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging experiment. Result:Fourteen compounds were isolated from the 95% ethanol extract of Violae Herba, including <italic>N</italic>-acetyl-1-ethyl ester glutamic acid (<bold>1</bold>), <italic>N</italic>-acetyl glutamic acid-1-ethyl-5-methyl ester (<bold>2</bold>), aurantiamide (<bold>3</bold>), <italic>rel</italic>-(2<italic>α</italic>,3<italic>β</italic>)-7-<italic>O</italic>-methylcedrusin (<bold>4</bold>), oleanolic acid (<bold>5</bold>), <italic>α</italic>-tocopherol-quinone (<bold>6</bold>), tectochrysin (<bold>7</bold>), isoscopoletin (<bold>8</bold>), esculetin (<bold>9</bold>), 24-ethylcholesta-4,24(28)<italic>Z</italic>-dien-3-one (<bold>10</bold>), stigmasta-4,25-dien-3-one (<bold>11</bold>), <italic>β</italic>-sitostenone (<bold>12</bold>), <italic>β</italic>-sitosterol (<bold>13</bold>), (24<italic>R</italic>)-3<italic>β</italic>-hydroxy-ethylcholest-5-en-7-one (<bold>14</bold>). Conclusion:Compound <bold>2</bold> is a new natural product, compounds <bold>1</bold>, <bold>4</bold>, <bold>6</bold>, <bold>7</bold>, <bold>10</bold>-<bold>12 </bold>are isolated from the genus <italic>Viola</italic> for the first time. Compound <bold>9</bold> has significant antioxidant activity, while compounds <bold>2</bold>, <bold>6 </bold>and<bold> 8</bold> have certain DPPH free radical scavenging activity.

ABSTRACT

Qingjin Huatanpang, first contained in Yixue Tongzhi, was composed of eleven medicinal materials of Scutellariae Radix, Gardeniae Fructus, Fritillariae Thunbergii Bulbus, Mori Cortex, Trichosanthis Semen Tostum, Citri Exocarpium Rubrum, Platycodonis Radix, Ophiopogonis Radix (core removed), Anemarrhenae Rhizoma, Poria and Glycyrrhizae Radix et Rhizoma. It is a classic prescription created by YE Wen-ling in Ming dynasty for treating pulmonary disease with phlegm-heat obstructing lung syndrome. With the significant functions of clearing heat and moistening lung, reducing phlegm and relieving cough, it has been included in the "Classic Catalogue of Ancient Classics (First Batch)". Modern pharmacological studies have shown that Qingjin Huatantang has multiple activities such as relieving cough and eliminating phlegm, anti-inflammatory, bronchodilation, and immunoregulatory, and now it is commonly used for treating infectious lung diseases, such as acute exacerbation of chronic obstructive pulmonary disease, community acquire pneumonia, bronchiectasis, acute and chronic bronchitis in a form of its modified prescription or its combined use with western medicine, consistent with the clinical application in ancient times. According to the literatures on the study of Qingjin Huatantang published in recent years, this paper summed up the historical evolution, compatibility analysis, chemistry constituents, quality control, advances in pharmacology research, and clinical uses, which can provide theoretical and experimental data reference for further research and development, and proposed to establish a biological activity assay for quality control based on the pharmacological effect such as immunoregulatory activity, which can improve its quality control method and provide a reference for other famous classical formulas.
