Chlorella pyrenoidosa No.2 was screened from five species of microalga Chlorella sp. for its higher lipid yield. Effects of medium components and culture conditions on cell growth as well as lipid ac-cumulation of C. pyrenoidosa No.2 were investigated and the results showed that the optimum medium rec-ipe was 20.0 g/L glucose,0.08 g/L glycine,1.0 g/L K2HPO4?3H2O,0.4 g/L MgSO4?7H2O and 0.004 g/L FeSO4?7H2O. The optimum culture temperature,initial pH,shaking rate and light intensity were 28℃,6.0,130 r/min and 650 Lux,respectively. Biomass and lipid content increased from 3.73 g/L and 40.15% to 6.56 g/L and 59.90% when Chlorella pyrenoidosa No.2 was cultivated under the above optimal conditions for 7 days,with lipid yield raised by 162%. Chlorella pyrenoidosa No.2 could produce lipid with xylose as carbon source,and so is potential for lipid production from renewable materials such as lignocellulose. GC analysis demonstrated that the fatty acid composition of the lipid was similar to that of vegetable oil and its unsaturated fatty acid content reached around 71%,thus it is a promising material for biodiesel production.

Objective To establish a liquid chromatography-tandem mass spectrometric ( LC-MS/MS ) for determination of clopidogrel in human plasma and stability of clopidogrel under different conditions,which was used subsequently to investigate the pharmacokinetics of clopidogrel in healthy Chinese volunteers. Methods Clopidogrel-d4 hydrogen sulfate was used as an internal standard. Separation was achieved on a WATERS Xterra? RP18 column (4.6 mm× 100 mm,3.5μm) with a mobile phase consisting of acetonitrile-0.1% formic acid (66:34) at a flow rate of 1.0 mL.min-1 within 3.2 min. ESI source was applied and operated in positive ion mode and multiple reaction monitoring (MRM). Plasma samples were pretreated by acetonitrile precipitation. Results A good linearity of clopidogrel was obtained in the concentration range of ( 5-5 000 ) ng.L-1. The lower limit of quantification was 5 ng.L-1. The intra-and inter-run precisions at three quality control levels were within 1.3%–9.9%,the relative deviation of the assay was within -6.2%-14.3%. The blood samples were stable when chilled with crushed ice ( 0℃) and cold water ( 4℃) ,as well as kept at room temperature ( 20℃) for 40 min. The plasma QC samples were stable at room temperature ( 20 ℃) for 4 h,at -70℃ for 38 days and during three freeze-thaw cycles. Hemolysis in blood sample drawn didn’ t affect the plasma concentration. The determination and the result of incurred sample reanalysis met the requirements. Conclusion A specific, rapid, sensitive and stable LC-MS/MS method is developed and validated for determination of clopidogrel in human plasma. The method is proven to be suitable for study of the pharmacokinetics of clopidogrel in healthy Chinese volunteers after a single oral dose of 75 mg clopidogrel hydrogen sulphate tablet.
