Fresh Rhizoma Gastrodiae (Tianma) was processed in a microwave oven at 2450 MHz in order to study the effect on the main chemical component changes taking place during microwave treatment. It was found that microwave affected the chemical composition of Tianma. Seven compounds, including gastrodin, gastrodigenin (p-hydroxybenzylalcohol), p-hydroxybenzaldehyde, vanillyl alcohol, vanillin, adenine, and 5-hydroxymethylfurfural, were identified in this study. As major active compounds, the contents of gastrodin and gastrodigenin in MWT Tianma were both twice as much as those in raw Tianma. Besides, the MS data show that there are still some unidentified compositions in Tianma, and there are also many converted compounds in MWT Tianma, which is worthy of further work. The results have indicated that microwave treated fresh Tianma might be helpful in designing the processing of traditional Chinese medicine and the application of microwave technology in traditional Chinese medicine needs to be researched further in the future.

The eighteen incompatible medicaments is an important theory in traditional Chinese medicine. The theory suggests that drugs in the eighteen incompatible medicaments can be toxic when used together.Veratrum nigrumL. andRadix paeoniae albabelong to the eighteen incompatible medicaments and have been prohibited for thousands of years. This study offers preliminary insight into the mechanism and chemical constituents responsible for the incompatibility and toxicity of these two agents. Specifically, we performed toxicology studies to identify and quantify the constituent substances of the two agents. Experiments revealed that acute toxicity increases when the dose ofV. nigrumL. is higher than, or equal to, RPA. UPLC-TOF-MS analysis showed that, although the volumes ofV. nigrumL. were the same, the content of some veratrum alkaloids changed significantly and had a trend toward a highly positive correlationr≥0.8with toxicity. This suggests that the increased toxicity of theV. nigrumL. and RPA combination was due mainly to increased content of the special veratrum alkaloids. The cytotoxicity of veratridine in SH-SY5Y cells was decreased with increasing paeoniflorin concentrations. This study provides insight into the mechanism behind the incompatibility theory of TCM.

Momordica cochinchinensis (Lour.) Spreng (M. cochinchinensis) is a deciduous vine that grows in Southeast Asia. It is known as gac in Vietnam and as Red Melon in English. Gac is reputed to be extremely benificial for health and has been widely used as food and folk medicine in Southeast Asia. In China, the seed of M. cochinchinensis (Chinese name: Mu biezi) is used as traditional Chinese medicine (TCM) for the treatment of various diseases. More than 60 chemical constituents have been isolated from M. cochinchinensis. Modern pharmacological studies and clinical practice demonstrate that some chemical constituents of M. cochinchinensis possess wide pharmacological activities, such as anti-tumor, anti-oxidation, anti-inflammatory, etc. This paper reviews the phytochemistry, pharmacological activities, toxicity, and clinical application of M. cochinchinensis, aiming to bring new insights into further research and application of this ancient herb.

Fast Dissolving/Disintegrating Dosage Forms (FDDFs) are a group of dosage forms which dissolve or disintegrate quickly, leading to fast distribution of active ingredients at the site of administration; thereby providing ease of oral ingestion of solid unit dosage forms and have the potential to enhance transmucosal absorption. With time, the use of FDDFs in alternative systems has significantly increased. Homeopathic systems and traditional Chinese medicine have embraced FDDFs for the delivery of active compounds. Most of the patents in this area are from China or by the Chinese innovators. In Europe and US, FDDFs have been extensively studied for the delivery of natural active compounds. It was fascinating to know that some new dosage forms and new routes of delivering active compounds are also making their way to the family of FDDFs. The dose of active compound, size of dosage forms, standardization of extracts, polyherbal mixtures, stability of active compounds, safety, efficacy and pharmacokinetics are challenging issues for developing FDDF herbal formulations or phytopharmaceuticals.

In the present review, the literature data on the chemical constituents and biological investigations of the genus Pedicularis are summarized. Some species of Pedicularis have been widely applied in traditional Chinese medicine. A wide range of chemical components including iridoid glycosides, phenylpropanoid glycosides (PhGs), lignans glycosides, flavonoids, alkaloids and other compounds have been isolated and identified from the genus Pedicularis. In vitro and in vivo studies indicated some monomer compounds and extracts from the genus Pedicularis have been found to possess antitumor, hepatoprotective, anti-oxidative, antihaemolysis, antibacterial activity, fatigue relief of skeletal muscle, nootropic effect and other activities.

Objective. Dipsaci Radix (DR) has been used to treat fracture and osteoporosis. Recent reports have shown that myeloid cells from bone marrow can promote the proliferation of lung cancer. However, the action and mechanism of DR has not been well defined in lung cancer. The aim of the present study was to define molecular mechanisms of DR as a potential therapeutic approach to treat lung cancer. Methods. Active compounds of DR with oral bioavailability ≥30% and drug-likeness index ≥0.18 were obtained from the traditional Chinese medicine systems pharmacology database and analysis platform. The potential target genes of the active compounds and bone were identified by PharmMapper and GeneCards, respectively. The compound-target network and protein-protein interaction network were built by Cytoscape software and Search Tool for the Retrieval of Interacting Genes webserver, respectively. GO analysis and pathway enrichment analysis were performed using R software. Results. Our study demonstrated that DR had 6 active compounds, including gentisin, sitosterol, Sylvestroside III, 3,5-Di-O-caffeoylquinic acid, cauloside A, and japonine. There were 254 target genes related to these active compounds as well as to bone. SRC, AKT1, and GRB2 were the top 3 hub genes. Metabolisms and signaling pathways associated with these hub genes were significantly enriched. Conclusions. This study indicated that DR could exhibit the anti-lung cancer effect by affecting multiple targets and multiple pathways. It reflects the traditional Chinese medicine characterized by multicomponents and multitargets. DR could be considered as a candidate for clinical anticancer therapy by regulating bone physiological functions.

Traditional Chinese medicine (TCM) has been used to treat disorders in China for ~1,000 years. Growing evidence has shown that the active ingredients from TCM have antibacterial, antiproliferative, antioxidant, and apoptosis-inducing features. However, poor solubility and low bioavailability limit clinical application of active compounds from TCM. “Nanoformulations” (NFs) are novel and advanced drug-delivery systems. They show promise for improving the solubility and bioavailability of drugs. In particular, “smart responsive NFs” can respond to the special external and internal stimuli in targeted sites to release loaded drugs, which enables them to control the release of drug within target tissues. Recent studies have demonstrated that smart responsive NFs can achieve targeted release of active compounds from TCM at disease sites to increase their concentrations in diseased tissues and reduce the number of adverse effects. Here, we review “internal stimulus–responsive NFs” (based on pH and redox status) and “external stimulus–responsive NFs” (based on light and magnetic fields) and focus on their application for active compounds from TCM against tumors and infectious diseases, to further boost the development of TCM in modern medicine.
