结果：蜘蛛香环烯醚萜35.6mg/kg、17.8mg/kg组能减缓胃排空和小肠推作用(P.05)，说明蜘蛛香环烯醚萜对正常小鼠胃肠功能有一定的抑制作用。1.2蜘蛛香环烯醚萜对利血平化小鼠胃肠功能的作用方法：小鼠每日腹腔注射利血平造模，同时灌胃给予蜘蛛香环烯醚萜71.2mg/kg、35.6mg/kg、17.8mg/kg、8.9mg/kg与空白组、模型组和越鞠保和丸组对照，给药6日后测定动物的胃排空率和小肠推进率。

D limonene was distributed among the culture flasks (200 mg/L). The flasks were incubated at 28oC on a rotary shaker (r/min=120) for 5 days. On completion, the culture broth were successively extracted with EtOAc. The extract was quantitatively measured by gas chromatography mass spectrometry analysis, The results showed that biocatalytic reactions were comprised of oxidation, including hydroxylation and ketonization which occurred at different positions of the D limonene, as well as hydrogenation, hydrolyzation, esterification and cyclic cleavage. These bacteria strains possess the distinctive biocatalytic capacities towards the D limonene. A series of terpenoids, including sesqui , di and tri terpernoids were also observed,which was accounted for D limonene had influence on the metabolites of marine bacteria.

以2216E为培养基，添加200mg/L的柠檬烯，在28℃，以120 r/min摇瓶培养5 d，用乙酸乙酯提取培养液，经GC MS分析其转化产物，结果显示，这些细菌能在柠檬烯的不同位置进行羟基化、羰基化等，并伴随有还原、水解、酯化、开环等反应，但转化能力和转化程度不同；在产物中，还检测到系列结构不同的其它萜类：包括倍半萜、二萜以及三萜等，这些萜类化合物的产生跟柠檬烯的加入有关，说明柠檬烯能影响细菌代谢产物的产生。

Samples were subjected to high pressure ranging from 100 to 500 MPa. After high pressure treatments, the flavour compounds were extracted by Solid-Phase Microextraction. Analysis was carried out by Gas Chromatography-Mass Spectrometry. The key flavour compounds of orange juice were three alkenes (namely limonene, myrcene and α-pinene), two alcohols (linalool and α-terpineol), three aldehydes, one ketone and two esters (ethyl butyrate and 3-OH-ethyl hexanoate).
