Traditional uses, botany, phytochemistry, and pharmacology of Lonicerae japonicae flos and Lonicerae flos: A systematic comparative review.

ETHNOPHARMACOLOGICAL RELEVANCE: Lonicerae japonicae flos (LJF) and Lonicerae flos (LF) belong to different genera of Caprifoliaceae with analogous appearances and functions. Historically, they have been used as herbal medicines to treat various diseases with confirmed wind-heat evacuation, heat-clearing, and detoxification effects. However, the Chinese Pharmacopoeia (2005 Edition) lists LJF and LF under different categories. AIM OF THE STUDY: Few studies have systematically compared the similarities and dissimilarities of LJF and LF concerning their research achievements. This systematic review and comparison of the traditional use, identification, and phytochemical and pharmacological properties of LJF and LF provides valuable insights for their further application and clinical safety. MATERIALS AND METHODS: Related document information was collected from databases that included Web of Science, X-MOL, Science Direct, PubMed, and the China National Knowledge Infrastructure. RESULTS: The chemical constituents and pharmacological effects of LJF and LF were similar. A total of 337 and 242 chemical constituents were isolated and identified in LJF and LF, respectively. These included volatile oils, cyclic ether terpenes, flavonoids, phenolic acids, triterpenoids, and their saponins. Additionally, LJF plants contain more iridoids and flavonoids than LF plants. The latter have a variety of triterpenoid saponins and significantly higher chlorogenic acid content than LJF plants. Pharmacological studies have shown that LJF and LF have various anti-inflammatory, antiviral, antibacterial, anti-endotoxic, antioxidant, anti-tumor, anti-platelet, myocardial protective, and hepatoprotective effects. CONCLUSIONS: This review was undertaken to explore whether LJF and LF should be listed separately in the Chinese Pharmacopoeia in terms of their disease prevention and treatment strategies. Although LJF and LF showed promising effects, their action mechanisms remains unclear. Specifically, their impact on gut microbiota, gastrointestinal tract, and blood parameters requires further investigation. These studies will provide the foundation for scientific utilization and clinical/non-clinical applications of LJF and LF, and the maximum benefits from their mutual use.

[Comparison of active components in different parts of Perilla frutescens and its pharmacological effects].

Perilla frutescens is a widely used medicinal and edible plant with a rich chemical composition throughout its whole plant. The Chinese Pharmacopoeia categorizes P. frutescens leaves(Perillae Folium), seeds(Perillae Fructus), and stems(Perillae Caulis) as three distinct medicinal parts due to the differences in types and content of active components. Over 350 different bioactive compounds have been reported so far, including volatile oils, flavonoids, phenolic acids, triterpenes, sterols, and fatty acids. Due to the complexity of its chemical composition, P. frutescens exhibits diverse pharmacological effects, including antibacterial, anti-inflammatory, anti-allergic, antidepressant, and antitumor activities. While scholars have conducted a substantial amount of research on different parts of P. frutescens, including analysis of their chemical components and pharmacological mechanisms of action, there has yet to be a systematic comparison and summary of chemical components, pharmacological effects, and mechanisms of action. Therefore, this study overviewed the chemical composition and structures of Perillae Folium, Perillae Fructus, and Perillae Caulis, and summarized the pharmacological effects and mechanisms of P. frutescens to provide a reference for better development and utilization of this valuable plant.

[UPLC characteristic chromatographic profile of Poria].

To establish a UPLC characteristic chromatographic profile analysis method to quickly assess Poria quality and provide basis fro controlling Poria quality. The UPLC characteristic chromatographic profiles of fifteen batches of Poria were determined by ACQUITY UPLC, with HSS T3 Column (2.1 mm x 100 mm, 1.8 microm) eluted with the mobile phases of water containing 0.05% phosphoric acid and acetonitrile in gradient mode. The detection wavelength was set at 243 nm. The common mode of the UPLC characteristic chromatographic profile was set up. There were 20 common peaks, seven of which were identified, and the similar degrees of the fifteen samples to the common mode were between 0.787 and 0.974. The method was so time-saving that it can be used for the quality control of Poria.

[UPLC characteristic chromatographic profile of Paeoniae Radix Alba].

OBJECTIVE: To develop an UPLC method of determining the characteristic chromatographic profiles of Paeoniae Radix Alba for quality control. METHOD: The UPLC characteristic chromatographic profiles of fifteen batches of Paeoniae Radix Alba were determined on an HSS T3 Column (2.1 mm x 100 mm, 1.8 microm) eluted with the mobile phases of water containing 0.05% phosphoric acid and acetonitrile in gradient mode. The detection wavelength was set at 230 nm. RESULT: The common mode of the UPLC characteristic chromatographic profile was set up. There were 15 common peaks, five of which were identified, and the similar degrees of the fifteen samples to the common mode were between 0.891 and 0.996. CONCLUSION: The method was time-saving and can be used for the quality control of Paeoniae Radix Alba.
