1.Substance basis research on Chinese materia medica is one of key scientific problems of inheriting, development and innovation of Chinese materia medica.
China Journal of Chinese Materia Medica 2015;40(17):3429-3434
The compound Chinese materia medica is the medication pattern of the traditional Chinese medicine for the disease prevention and treatment. The single Chinese materia medica (mostly in decoction pieces) is the prescription composition of the compound Chinese materia medica. The study of the effective substance basis of Chinese materia medica should be based on the chemical compositions of the compound Chinese materia medica as an entry point considering the different status of "Monarch, Minister, Assistant, and Guide" for a certain single Chinese materia medica in the different compound Chinese materia medica while substance basis research of a certain single Chinese materia medica should be a full component analysis as well as both stable and controllable quality. Substance basis research on Chinese materia medica is one of key scientific problems of inheriting, development and innovation of Chinese materia medica.

2.GC-MS analysis of essential oil from the seeds of Myristica fragrans Houtt in Indonesia
China Journal of Traditional Chinese Medicine and Pharmacy 2006;0(09):-
Objective: To analyze the chemical constituents of the essential oil extracted from the seeds of Myristica fragrans Houtt.(nutmeg) in Indonesia and to provide qualities control scientific foundations.Methods: The essential oil was extracted by steam distillation and separated with GC capillary column.The relative content of every compound was determined by normalization method and the chemical compositions were evaluated by GC-MS.Results: Ninety-three chromatographic peaks were isolated and sixty-one compounds were identified,accounting for 97.62% of the total essential oil in nutmeg.Conclusion: The essential components of nutmeg in Indonesia is monoterpenoids and it's derivatives,accounting for 78.87% of the total essential oil.And phenolic compounds were the secondary composition,accounting for 16.79%.The essential oil contains safrole,which can induce genetoxicity and mutagenicity in animal,and myristicin and elemicin which can induce illusion.So,it must be careful when Myristica fragrans Houtt was used.

Purpose The aim is to establish a simple method to extract superoxide dismutase(SOD) from pig blood red cells.Methods A combined method-microwave heating and adding Cu2+ into the suspension-was used to extract SOD from the red cells. Results The undesired proteins were denatured by microwave heating and SOD was partly purificated in comparison with hemolysis. The processing time of the former was much shorter than the latter. Conclusion A novel cell disruption microwave heating, was a rapid and effective technique for the primary extraction of SOD.

The volatile compounds of trogopterorum feces were collected by using a simultaneous distillation and extraction (SDE) equipment. The chemical composition of the enriched volatile was examined by means of capillary gas chromatography (GC) and combined GC-mass spectrometry (MS). Fifty one constituents of the volatile were preliminarily identified by GC-MS, which amounted to 56.3% of the total peak area. Of these compounds, 33 were further verified by measuring their temperature-programmed retention indexes (TPRI) or retention times. They amounted to 35.7 % of the total peak areas. The main constituents of the volatile are dedecanoic acid (7.00%);alphacedrol (4.41%); pyrazine, tetramethyl-(4. 10%); tetradecanoic acid (3.37%); ethanone, 1-(3-methylphenyl)- (2.53%); benzaldehyde (2.42%); phenol, 2-methoxy-(2.11% ). The compound classes consist of alcohols (10), ketones (8), aldehydes (6), olefines (5), acids (4), and phenols (4).

Object To study the ultrastructure destruction of plants in the process of microwave assisted solvent extracion and its mechanism.Methods Cell structures of fresh leaves of Ginkgo biloba L. were observed by transmission electron microscpoe.Results The cell structure changed when the leaves were under microwave radiation or soaked by solvents or heated, such as plasmoysis, destruction of cell organellaes, disappearance of starch grain and so on, while the cell wall was not broken both in microwave assisted solvent extraction and in traditional heating extraction.Conclusion Microwave radiation could lead to the relaxation of the cell structures, but not be enough to make the cell wall broken.

Objective To carry out a systematic study on the chemical constituents in the fruits of Momordica grosvenori. Methods To isolate pure compounds by using repeated column chromatography, while the structure of a new compound was determined by detailed spectral analysis. Results Four cucurbitane triterpenoid glycosides, mogroside Ⅱ_E(Ⅰ), mogroside Ⅲ(Ⅱ), grosmomoside Ⅰ (Ⅲ), and mogroside Ⅴ (Ⅳ) were isolated from the 50% ethanolic extract of the fruits of M. grosvenori. Conclusion Grosmomoside Ⅰ is a new compound identified as mogrol-3-O-?-D-glucopyranoside-24-O-{[?-D-glucopyranosyl(2-1)]-[?-D-glucopyranosyl (6-1)]-?-D-galactopyranoside} and the other three compounds are known compounds.

Sphingolipids are structural components of cellular membranes.Their metabolites,such as ceramide,sphingosine,and sphingosine 1-phosphate are important bioactive molecules,which act as the first or second messengers regulating various cellular activities,including proliferation,survival,migration and neovascularization in vitro and in vivo tumor models.Sphingosine kinases 1(SPK1) is a critical regulator of the balance between ceramide and S1P.Recent studies show that ceramide,SPK1 and S1P can regulate many of the hallmarks of cancer.These studies suggest that these metabolites can serve as novel targets for cancer therapy.
