Comprehensive Utilization of Non Medicinal Parts In Traditional Chinese Medicinal Materials

Although the amount of traditional Chinese medicine resources are large, but limited after all, And the waste phenomenon is very serious, reasonable utilization of medicinal plants are the key, develop the medicinal value of non-medicinal parts in the traditional Chinese medicine, making them fully comprehensive utilization, improve the added value of Chinese herbal medicine, and the research results will have an important role in guiding the comprehensive utilization of medicinal plants. It is possible to use the non-medicinal parts of Chinese herbal medicine as the production of biological fertilizer, the extraction and separation of the effective components, the expansion of the drug site, the rapid breeding of the material, the Chinese herbal feed additives and so on.

Steroidal saponins with induced platelet aggregation activity from the aerial parts of Paris verticillata

In order to utilize and protect the resources of Rhizoma Paridis rationally, we carried out a phytochemical investigation on the non-medicinal (aerial) parts of Paris verticillata that led to the isolation of fifteen steroidal saponins. Among them, three are new spirostanol saponins, named parisverticosides A–C (1–3), as well as one new cholestane glycoside, named parisverticoside D (4). Their structures were elucidated by extensive spectroscopic analysis and acid hydrolysis. The aglycone of compound 1 is a new spirostane and identified as (23S,24S,25S)-spirost-5-en-1β,3β,23, 24-tetraol. The selected isolates were evaluated for induced platelet aggregation activity and compound 5 showed 62% maximal platelet aggregation rate at the concentration of 300μg/mL.

Research practices of conversion efficiency of resources utilization model of castoff from Chinese material medica industrialization

The industrialization chains and their products, which were formed from the process of the production of medicinal materials-prepared drug in pieces and deep processed product of Chinese material medica (CMM) resources, have generated large benefits of social and economic. However, The large of herb-medicine castoff of "non-medicinal parts" and "rejected materials" produced inevitably during the process of Chinese medicinal resources produce and process, and the residues, waste water and waste gas were produced during the manufactured and deep processed product of CMM. These lead to the waste of resources and environmental pollution. Our previous researches had proposed the "three utilization strategies" and "three types of resources models" of herb-medicine castoff according to the different physicochemical property of resources constitutes, resources potential and utility value of herb-medicine castoff. This article focus on the conversion efficiency of resources model and analysis the ways, technologies, practices, and application in herb-medicine cast off of the conversion efficiency of resources model based on the recycling economy theory of resources and thoughts of resources chemistry of CMM. These data may be promote and resolve the key problems limited the industrialization of Chinese material medica for long time and promote the realization of herb-medicine castoff resources utilization.

Several common types of counterfeit and inferior drugs in Chinese medicinal materials market

Though there are many species of counterfeit and inferior drugs of Chinese Medicinal Materials in the market, the means of fabrication is common. According to our investigating and reports in the literature it is found that the counterfeits and inferior drugs exist in 4 styles: counterfeits, reused medicinal materials and their slices which have been extracted by boiling water or ethanol, medicinal materials and their slices which have been added with non-medicinal parts or chemicals, medicinal materials which have no enough growth time or have been reserved for a long time. Through summarizing the styles and their common characteristics of the counterfeits and inferior drugs,it is helpful to raise vigilance and detect them.
