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.

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.

Cancer is a serious threat to human health. Fungal polysaccharide is a polar biological macromolecule with low toxicity. It has a wide range of biological activities, including immune regulation, antitumor activity, and antiviral activity. In recent years, the research results have shown that polysaccharides from fungus in traditional Chinese medicine have excellent antitumor effect in liver cancer, gastric cancer, breast cancer, colon cancer, esophageal cancer, and lung cancer. Therefore, the research and development of fungal polysaccharides are of great significance for the development of antitumor drugs in the future.

Ganoderma lucidum is generally called “Lingzhi or Reishi”, and also be a Traditional Chinese medicine utilized in over 2000 y for their better therapeutic activity like antitumor, antiallergenic, antiviral, hepatoprotective, antioxidant, hypotensive, immunomodulator, hypoglycemic, anti-inflammatory, antithrombotic, antibacterial and many other health benefits. Ganoderma lucidum is one of the oldest herbal remedy found and grow in wide variety parts on deciduous trees (dead/dying tree) specifically in oak, pyrus, maple, elm, willow, sweetgum, magnolia, locust, acer, betula, castanea, coryolus, fagus, populus, plums and other plants species. It also be contains 400 major bioactive chemical constituents include polysaccharides, triterpenoids, polysaccharide-peptide complex, β-glucans, lectins, natural germanium (Ge), adenosine, phenols, steroids, amino acids, lignin, vitamins, nucleotides or nucleosides possesses specific curative properties and formed a wide variety of viable products from Ganoderma fruiting bodies, mycelia, spores i.e. coffee, powder, dietary enhancements, tea, spore items, drinks, syrups, toothpastes, cleansers or creams. Many in vitro or in vivo analyses with regards Ganoderma lucidum evidenced their antitumor activity but some conducted clinical studies are questionable and remains undefined for their antitumor effect. Though, we reviewed and summarized in this article about treatment and various pharmacological mechanism against tumor with respect to extract (polysaccharide and triterpenoid) of Ganoderma lucidum.

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.

The traditional Chinese medicine fufang preparation "Xian-Ling-Gu-Bao" capsule (XLGB), which is composed of six herbal medicines, is popularly used for the treatment of osteoporosis. A reliable and effective method using LC-linear ion trap (LTQ)/Orbitrap mass spectrometry for rapid screening and identification of chemical constituents in "Xian-Ling-Gu-Bao" capsule is described in this paper. Based on the UV spectrum, mass spectrum, and the chemical components isolated from the original plants of XLGB, 118 compounds were identified or tentatively characterized, including 58 flavonoid glycosides, six prenylated flavonones, five prenylated isoflavones, six prenylated chalcones, four xanthone C-glycosides, 13 saponins, eight phenolic acids, five coumarins, three lignans, three iridoids, five phenethyl alcohol glycosides, one tanshinone and one alkaloid. This work might be helpful for the quality control and further pharmacokinetic studies of XLGB, and provided a good example for the rapid identification of chemical constituents in traditional Chinese medicine fufang preparation. Moreover, the identification strategy for the linkages of sugar residues in flavonol O-glycosides was summarized in the study. The diagnostic fragment ions at m/z 185 [ C 12 H 9 O 2] and 157 [ C 11 H 9 O ], which distinguish C -6 and C -8 prenylated flavonoids, were reported for the first time.
