    To determine the content of trehalose in transgenic Aloe by gas chromatography (GC),1-Methyl-imidazol,Hydroxylammonium chloride and Acetic anhydride were used to derivative the trehalose.The difference of the retention time among the same carbohydrate derivatives is 3s by this method.And it can separate the glucose,milk sugar,sucrose and trehalose clearly.The results showed a good linear relationship within a range from 3.697×10-9 g to 28.661×10-9 g,and the liner correlation coefficient of the trehalose is 0.998 6.The content of trehalose in the three-year,five-year aloe (Aloe vera.L) and aloe transformed by ostA were determined by GC.The results show that the trehalose of the fiveyear aloe (Aloe vera.L) is 1.59 times as great as the three-year.The content of trehalose in five-year aloe is 1.103×10-5 g per 10g,and 6.905×10-6 g per 10g in three-year aloe.The content of trehalose is 1.614×10-5 g per 10g in aloe transformed by ostA which is 2.33 times as great as the three-year aloe (Aloe vera.L).The results prove that the ostA gene from E.coli is successfully transformed to aloe and expressed.

    〗Five conventional constituents in 202 flue-cured tobacco samples from two tobacco areas (Longshan and Sangzhi) of Xiangxi in 2006 were analyzed and evaluated.By the comparison with that from Yunnan,it was found that the content of total sugar in Xiangxi tobacco was higher than the sugar range of good quality tobacco,but lower than that in Yunnan tobacco.For most tobacco samples in Xiangxi,the content of nicotine was in a suitable but slightly high level and higher than that from Yunnan.The content of Cl-1 and total nitrogen was within a suitable range,as well as the ratio of TS/alkali and K/Cl.The ratio of TS/alkali in tobacco from Xiangxi was generally lower than that from Yunnan and TN/alkali ratio lower than good quality tobacco.In order to further improve the quality of tobacco in Xiangxi areas,it is necessary to improve bionomic and cultivated conditions and to utilize flue-cured and modulation technique so as to reduce the content of total sugar and nicotine and to increase the content of K in Xiangxi tobacco.
