Antioxidant Activity of 50 Traditional Chinese Medicinal Materials Varies with Total Phenolics

This study was designed to determine the total phenolic content of 50 herbs and to examine their antioxidant potential. In the sample preparation, 60% ethanol was chosen as the extraction solvent for the subsequent experiments. Folin-Cicolteau phenol reagent and a colorimetric method were used to determine the total phenolic content of the selected herbs. The result showed that total phenolic content of those herbs ranged from 2 to 185 mg/g. In antioxidant assay, the ferric reducing/antioxidant power (FRAP) values ranged from 2 to 134 mg GAE/g;the IC50 values of DPPH?·, ·OH and ?scavenging were in the range of 0.06 - 5.50 mg/mL, 0.017 - 0.636 mg/mL and 0.050 - 0.681 mg/mL respectively. Flos caryophylli was the exceptant in the ?scavenging assay because there was no linear relation between the concentration and the scavenging percentage. Compared to gallic acid, ascorbic acid and butylated hydroxytoluene (BHT) in antioxidant assay as positive control, the most potential antioxidant herbs were Cacumen platycladi, Radix et Rhizoma rhei, Rhizoma rhodiolae crenulatae, and Rhizoma sanguisorbae with considerable content of phenolics. Especially, a positive and significant correlation was found between the total phenolic content and FRAP value or DPPH· scavenging percentage.

Reason Analysis and Risk Prevention of Soaring Price of Traditional Chinese Medicinal Materials

In recent years,the price of traditional Chinese medicinal materials soars continuously,and the resulting price risk increasingly looms large,which has critically affected midstream and downstream industries and peoples' demand for drug,and imperiled healthy and orderly development of traditional Chinese medicinal industries.Based on the status quo of continuous skyrocketing price of traditional Chinese medicinal materials at present,we winkle out the root cause of soaring price as follows:the supply and demand lose balance;the production costs hike up;there are other factors responsible for soaring price.This paper further analyses the impact of sharp increase in price of traditional Chinese medicinal materials on all links of industry chain as follows:the medicinal herb growers never benefit from soaring price;the counterfeiters and forgers in midstream industry increase;the gross profit rate of Chinese medicine enterprises declines.In accordance with the risk arising from abnormal fluctuation in price of traditional Chinese medicinal materials,corresponding precautionary measures are put forward as follows:promote the quality of traditional Chinese medicinal materials through management of value chain;curtail the production and management cost of traditional Chinese medicinal materials through management of organization chain;stabilize price of traditional Chinese medicinal materials through management of information chain;reduce transaction cost of traditional Chinese medicinal materials through management of logistics chain.

Novel technologies and models for studying pharmacological activities of traditional Chinese medicine for promoting blood circulation and removing blood stasis

OBJECTIVE Our previous studies demonstrated that various ingredients from the traditional Chinese medicine(TCM)for promoting blood circulation and removing blood stasis,as exemplified by cryptotanshinone and salvianolic acid B,exerted striking effects on modulating angiogenesis and vascular permeability,which suggests that they may be effective in treating vascular leak-driven diseases(e.g.tumor,cerebral cavernous malformation and diabetic retinopathy).However,the lack of reliable and advanced technologies and models sets up difficult hurdles for better understanding the role of TCM for promoting blood circulation and removing blood stasis.To this end,this study is to outline numerous cutting-edge platforms that can be utilized for exploring the function of TCM for promoting blood circulation and removing blood stasis in vascular leak-driven diseases.METHODS Two-photon laser scanning fluorescence microscopy was used to observe the interactions between neutrophils and blood vessels in a real-time manner.Dynamic flow system was employed to mimic the in vivo behaviors of neutrophils.RIP1-Tag5 spontaneous pancreatic cancer model was used to study the function of tumor blood vessels.CCM2ECKO(deletion of CCM2 in endothelial cells)mice were employed to establish the cerebral cavernous malformation(CCM)animal model.Micro-computed tomography(micro-CT)was utilized to assess the CCM lesion.Müller cell-knockout mouse model was used to study the progression of diabetic retinopathy.Vascular permeability in this model was assessed by fluorescein angiography.RESULTS The interactions between neutrophils and endothelial cells involve a series of complicated processes,including rolling,adhesion,intraluminal crawling and transmigration,which were all monitored in vivo by two-photon laser scanning fluorescence microscopy in a real-time manner.Dynamic flow system was capable of recapitulating the biological behaviors of neutrophils in vitro.Tumor vascular function in particular vascular perfusion could be assessed in the RIP1-Tag5 spontaneous pancreatic cancer model.In terms of CCM studies,specific deletion of CCM2 in endothelial cells resulted in the initiation of CCM lesion.The size and number of CCM lesions could be visualized and quantified by micro-CT.Furthermore,the Müller cell-knockout mouse model was able to precisely reflect the clinical symptoms of diabetic retinopathy.Vascular leak could be monitored at different time points using fluorescein angiography.CONCLUSION An array of high technologies and animal models can be used in investigating the occurrence and progression of multiple vascular leak-driven diseases.The pre-clinical and clinical studies of TCM for promoting blood circulation and removing blood stasis provide fundamental support for the application of the above-mentioned platforms,with the purpose of uncovering the scientific basis of TCM for promoting blood circulation and removing blood stasis.

Bioactive constituents of animal-derived traditional Chinese medicinal materials for breast cancer:opportunities and challenges

Breast cancer is globally the most common invasive cancer in women and remains one of the leading causes of cancer-related deaths.Surgery,radiotherapy,chemotherapy,immunotherapy,and endocrine therapy are currently the main treatments for this cancer type.However,some breast cancer patients are prone to drug resistance related to chemotherapy or immunotherapy,resulting in limited treatment efficacy.Consequently,traditional Chinese medicinal materials(TCMMs)as natural products have become an attractive source of novel drugs.In this review,we summarized the current knowledge on the active components of animal-derived TCMMs,including Ophiocordyceps sinensis-derived cordycepin,the aqueous and ethanolic extracts of O.sinensis,norcantharidin(NCTD),Chansu,bee venom,deer antlers,Ostrea gigas,and scorpion venom,with reference to marked anti-breast cancer effects due to regulating cell cycle arrest,proliferation,apoptosis,metastasis,and drug resistance.In future studies,the underlying mechanisms for the antitumor effects of these components need to be further investigated by utilizing multi-omics technologies.Furthermore,large-scale clinical trials are necessary to validate the efficacy of bioactive constituents alone or in combination with chemotherapeutic drugs for breast cancer treatment.
