The cell of Gardenia jasminoides Bills has priority to using glucose;(5) The capacity of GJEP production was decreased in later stage, one of the important reason was that the carbon source in the medium was used up;(6) Excessive nitrogen source was not good for producing GJEP;(7) Auxins have more affective on cell growth and polysaccharide production.

我们采用了正交实验设计确立了板子多糖的提取和Saveqe法除蛋白的耕，结果发现，用50倍体积的碱水在80℃下提取2小时，再经过一系列醇析、脱色和脱蛋白等处理，桅子果实多糖的得率为1.74％，是文献报道的3倍。

Pesticides were extracted from tea with hexane-acetone (volume ratio is 1:1) in an ultrasonic bath and cleaned up on a Florisil and neutral alumina column, then were determined by gas chromatography with negative chemical ionization mass spectrometric detection in the selected ion monitoring mode, and with heptachlor epoxide as the internal standard. Spiked blank samples were used as standards to counteract the matrix effect observed in the chromatographic determination.
