Mongolian medicine: History, development and existing problems / 中草药·英文版

Mongolian medicine (MM) is an important part of Mongolian culture. Exploration of MM can play a crucial role in the prevention and treatment of various diseases and can help provide better health care globally. In this article, we gave a brief introduction to the origin and development of MM, the theoretical system of MM, the principles of Mongolian materia medica formula, the modern research on Mongolian materia medica and the quality control of Mongolian materia medica. The present situation and outlook of MM were also discussed.

Mongolian medicine in treating type 2 diabetes mellitus combined with nonalcoholic fatty liver disease via FXR/LXR-mediated P2X7R/NLRP3/NF-κB pathway activation / 中草药·英文版

Type 2 diabetes mellitus (T2DM) and nonalcoholic fatty liver disease (NAFLD) are the most problematic metabolic diseases in the world. NAFLD encompasses a spectrum of severity, ranging from simple steatosis to non-alcoholic steatohepatitis (NASH) and fibrosis, increasing the risk of cirrhosis and hepatocellular carcinoma. Importantly, NAFLD is closely linked to obesity and tightly interrelated with insulin resistance and T2DM. T2DM and NAFLD (T2DM-NAFLD) are called as the Xike Rixijing Disease and Tonglaga Indigestion Disease respectively, in Mongolian medicine. Xike Rixijing Disease maybe develop into Tonglaga Indigestion Disease. Forturnately many Mongolian medicines show efficient treatment of T2DM-NAFLD, such as Agriophyllum squarrosum, Haliyasu (dried powder of camel placenta), Digeda-4 (herbs of Lomatogonium carinthiacum, rhizomata of Coptis chinensis, ripe fruits of Gardenia jasminoides, herbs of Dianthus superbus), Guangmingyan Siwei Decoction Powder (Halite, ripe fruits of Terminalia chebula, rhizomata of Zingiber officinale, fruit clusters of Piper longum), Tonglaga-5 (ripe fruits of Punica granatum, barks of Cinnamomum cassia, ripe fruits of Amomum kravanh, fruit clusters of Piper longum, flowers of Carthamus tinctorius), Tegexidegeqi (rhizomata of Inula helenium, ripe fruits of Gardenia jasminoides, rhizomata of Platycodon grandiflorum, rhizomata of Coptis chinensis, heartwood of Caesalpinia sappan), Ligan Shiliu Bawei San (ripe fruits of Punica granatum, barks of Cinnamomum cassia, ripe fruits of Amomum kravanh, fruit clusters of Piper longum, flowers of Carthamus tinctorius, ripe fruits of Amomum tsao-ko, rhizomata of Zingiber officinale), etc. Principles of Mongolian medicine in treating diseases: by balancing “three essences or roots” and “seven elements”, strengthening liver and kidney function, transporting nutrients to enhance physical strength and disease resistance, and combined with drugs for comprehensive conditioning treatment. However, their molecular mechanisms remain unclear. In this review, we prospect that Mongolian medicines might be a promising treatment for T2DM-NAFLD by activating P2X7R/NLRP3/NF-κB inflammatory pathway via lipid-sensitive nuclear receptors (i.e., FXR and LXR).

Extraction and structure elucidation of three lignans from peeled dried roots and stems of Syringa pinnatifolia / 中草药

Objective: To study the chemical constituents from the peeled dried roots and stems of Syringa pinnatifolia. Methods: The chemical constituents from the peeled dried roots and stems of S. pinnatifolia were isolated and purified by silica gel and Sephadex LH-20 column chromatography, and preparative HPLC. The structures were identified by spectral methods. Results: Three compounds were obtained and identified as lignan, namely 3, 3', 4-trimethoxy-4', 8, 9, 9'-tetrahydroxy simple lignan (1), 3, 3', 4, 9-tetramethoxy-4', 8-dihydroxy-9'-ethoxy simple lignan (2), and 3, 3', 4, 9-tetramethoxy-4', 8, 9'-trihydroxy simple lignan (3). Conclusion: Compounds 1-3 are new, named syripinnalignan C, syripinnalignan D, and syripinnalignan E.

Simultaneous Determination of Seven Flavonoids in Aerial Parts of Artemisia frigida by HPLC / 中草药·英文版

Objective To establish an HPLC method for the determination of seven flavonoids from the aerial part of Artemisia frigida.Methods Hypersil ODS-2 (300 mm× 4.6 mm,5 μm) column was used,with acetonitril-0.2％ phosphoric acid (gradient elution) as a mobile phase,and the detection wavelength was at 283 nm with flow rate at 1mL/min.Results All calibration curves showed good linear regression (r ＞ 0.9990) within the tested range.All average recovery was more than 98.00％ and RSD was less than 3.0％ (n =6).Conclusion The method is steady and with good repeatability,and could be used to determine the content of flavonoids in A.frigida from different areas.
