RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Sparganii Rhizoma (SR), a traditional Chinese medicine (TCM), is the rhizome of Sparganium stoloniferum Buch.-Ham. mainly distributed in East Asia. It has been used for eliminating blood stasis, promoting the flow of Qi, removing the retention of undigested food and relieving pain in China for hundreds of years. AIM OF THE REVIEW: This review summarizes comprehensive information in traditional clinical application, processing, phytochemistry, pharmacology, quality control and toxicity of SR, in exploring future scientific and therapeutic potentials. MATERIALS AND METHODS: Pertinent information was systematically collected from several electronic scientific databases (e.g., Web of Science, PubMed, China Knowledge Resource Integrated, Springer, Elsevier, ScienceDirect, and Google Scholar), PhD and MS dissertations, and classic Chinese medical books. RESULTS: SR is a gynecological drug which is often used to treat dysmenorrhea, mass in the abdomen, amenorrhea due to blood stasis, and abdominal distension in TCM. Two kinds of processed products of SR are included in Chinese Pharmacopoeia, which have better pharmacological effects than the crude herb. Approximately 180 compounds have been identified from SR, including phenylpropanoids, flavonoids, anthraquinones, organic acids, alkaloids, steroids, volatile oils, diarylheptanes, etc. The crude extracts and isolated components of SR have been reported to have anti-tumor, antithrombotic, estrogen antagonistic , anti-inflammatory, analgesic, antioxidant, anti organ fibrosis and other pharmacological activities. SR also has reproductive toxicity. CONCLUSIONS: As an important TCM, SR has been demonstrated by modern pharmacological researches to have significant bioactivities, especially on anti-tumor, antithrombotic, and estrogen antagonistic activities. These activities provide prospects for the development of new drugs and therapeutics for future applications. Nevertheless, quality control and evaluation, in-depth pharmacological mechanism, and toxicological effect of SR require further detailed research.

RESUMO

Nü-Er-Cha, produced from the leaves of Rhamnus heterophylla Oliv., is known as an herbal tea and used in the treatment of bleeding, irregular menstruation and dysentery. A method was developed for the quality assessment of herbal tea, Nü-Er-Cha, adopting physical parameters, chemical constituents and sensory profiles as various potential factors. Their inner relationship was mined by multivariate statistical analysis tools, and the three factors were integrated by a technique for order preference by a similarity to ideal solution (TOPSIS) approach to comprehensively analyze the characters of Nü-Er-Cha. Viscosity was also introduced to the physical parameter determination besides conductivity, pH and color. Seven common peaks of eight batches of Nü-Er-Cha were marked by a high performance liquid chromatography (HPLC) fingerprint. They were further identified by HPLC mass spectrometry/mass spectrometry (HPLC-MS/MS) as hydroxybenzoic acids and flavanol glycosides. Fifty trained members participated in the sensory evaluation. Significant correlations between total sensory scores and conductivity, viscosity as well as pH were observed, a relatively innovative result for the quality assessment of herbal teas. The common peaks, belonging to hydroxybenzoic acids and flavanol glycosides, were mainly related to the color of infusions and leaves. The result of the TOPSIS analysis showed that S3 and S4 ranked as the top two in the comprehensive quality assessment. This may be related to rhamnetin triglycoside with a galactose/glucose and two rhamnoses, which had a higher peak response in S3 and S4 than that in the other samples. The present study may contribute to a better understanding of the relationship regarding physical properties, chemical composition and sensory profiles, and it may supply ideas for the comprehensive quality assessment of the herbal tea Nü-Er-Cha.
