The jellyfish is a popular seafood in South-East Asia. It can also be found throughout Europe in many Chinese shops, which despite being well-organized from a commercial perspective, often disregard rules on product traceability. Therefore because jellyfish has still not been officially defined by the European Legislation on Food Hygiene, we performed a survey on fifty-six jellyfish products sold on the Italian market. This was done by assessing label compliance with European law and with the new Chinese Food Safety Law of 2009. Our survey found many incongruences and shortfalls including the presence of a trade name referring to vegetables or a lack of an unequivocal specification of ingredients. Focus is therefore needed on the possible hazards associated with the consumption of jellyfish products. In addition, regulations need adjusting in order to create more transparent marketing and sales practices. © 2012 Elsevier Ltd.

To study the macroscopic and microscopic characteristics of Zhuang medicine Tetrastigma planicaule. Macroscopic and microscopic identification were studied. The microscopic characteristics were significant. The root had more than 10 layers of cork cells arranging in line. The starch grain and calcium oxalate cluster crystals distributed in the phloem parenchymas, and mucilage cells scattered in the cortex of the stem. There were 8 vascular bundles in the vein of leaves. This study provides a scientific basis for the identification and utilizing of Tetrastigma planicaule.

Over the years, the European Union has developed a comprehensive legal framework to ensure seafood traceability. In fact, in this sector, where the complexity of the marketing patterns has reduced the efficiency of controls, frauds are becoming widespread. Moreover, the rapid growth of Chinese communities has led to an increase of importations from Asia, which sometimes do not fully respect rules on traceability. In this study, we performed a survey on seafood products collected from the market of the Chinese community of Prato (Italy), to assess the frequencies and types of non-compliance in the light of the requirements established by the European traceability legislation on fisheries and aquaculture. Examination of labels and contents of Chinese seafood products imported to Italy found that 83% did not meet EU requirements for traceability.Overall, this survey put into light the difficulties of the ethnic communities to conform to the European rules, the need to adapt the control system to the fast developing trade reality at all levels of the chain and the advisability to create standards that could be adopted worldwide. © 2013 Elsevier Ltd.

To establish an high-performance liquid chromatography-diode array detection (HPLC-DAD) method for the first time to simultaneously determine five major bioactive depsides, salianic acid A, protocatechuic acid, protocatechuic aldehyde, salvianolic acid G and salvianolic acid D in freeze-dried Dan-Shen injection. Chromatographic separation was carried out on a Phenomenex Hydro-C18 reserved-phase column (4.6×250 mm, 4 μm) by stepwise gradient elution with acetonitrile and water (0.1% trifluoroacetic acid, v/v) as the mobile phase. The UV detection wavelength was set at 281 nm for salianic acid A and protocatechuic aldehyde, 260 nm for protocatechuic acid, 228 nm for salvianolic acid G and 322 nm for salvianolic acid D, respectively. Good linear relationships were observed between peak areas and concentrations with r 2 values above 0.9997 for all the analytes. Average recoveries for the five major actives ranged from 98.3 to 99.4%. This method was rapid, sensitive, accurate, and could be readily applied to the quality assessment of freeze-dried Dan-Shen injection. © 2011 Academic Journals.

Mathematical expression was established for evaluating anticancer efficacy of samples of Z. nitidum to human tumor cells based on their infrared fingerprints. Chloroform extracts of the root of Z. nitidum from different habitats in China were used as subject samples to do anticancer experiments on two strains of human tumor cells, 7901 and Hela cells. Meanwhile, their fingerprints of infrared spectra were obtained. Screening arguments of backward elimination method was adopted to establish the spectra-effect correlation between infrared fingerprint and pharmacology data. The results showed that deviations of the predictive values from the true values were within ±10% for the two kinds of tumor cells, suggested that there was close correlation between infrared fingerprint and biological activity of Z. nitidum. The model implied that alkaloids in Z. nitidum have main effect on tumor cells.
