| Aloe vera L.var is a kind of plant with very high medicine using.Many declining a blood sugar function and suppressing a germ function,different live composition of the part of aloe, sugar of the regulations of contents and its dynamic state varieties was launched in this paper,the full text result as follows:The database pulls the normally small rat serum glucose lower by the dose of Aloe vera L. var polysaccharides,three amount of set rightness to present amount of contral,medium,low three amount of set and blank set comparison be learned a t examination by covariance and the difference all has shows markedly(P＜0.001,P＜0.01);The comparison difference of male matched control and blank set shows markedly(P＜0.001);The database pulls Aloe vera L.var polysaccharides high,medium,low three amount of set rightness big rat serum influence and blank matched control comparison of the insulin be learned at examination by covariance and the difference doesn't markedly(p＞0.05);The comparison difference of male matched control and blank set doesn't markedly(P＞0.05);The database pulls Aloe vera L.var polysaccharides functions that the sugar lowers normally big rat serum a high blood sugar level to present amount of dependence.High,medium,low three amount of set and blank matched control comparison be learned at examination by covariance and the difference shows diversity very markedly (P＜0.001,P＜0.01);positive matched control and blank set comparison,the difference shows difference very much(P＜0.001),the high amount of set surpass a positive matched control.It show Aloe vera L.var polysaccharides to have a certainly decline a blood sugar function.Through researching on micros prohibition impact of Aloe vera L.var,the result indicate, the micro prohibition effect is different by different concentrate juice of Aloe vera L.var and different high temperature,in experiments,prohibition effect on the juice of Aloe vera L.var enhances by the rise of concentrate,otherwise,the effect of prohibiton of Bacillus subtilis is not apparent and lower by low of concentration juice of Aloe vera L.var in the election arrange of experiment.this indicate that the micros prohibition need high concentration.in high concentration condition,the effect of micros prohibition is good by heat.Under the same conditions,the aloin in aloe leaf,leaf epidermis,root,and different parts of Aloe vera L.var were compared by HPLC determination method,The result shows:the content of aloin in leaf epidermis(79.88±0.86μg/g) is approximately 14 times of which inthe leaf (5.71±0.06μg/g ),and it has a high content of aloin(22.98±0.58 mg/g) in the root of Aloe vera L.var also.In order to determine the optimal harvest time and better utilizing aloe resources,the dynamic changes of aloin in different growing period of Aloe vera L.var were studied through determinating,the content of aloin by HPLC.The result shows:the preferable harvest time of Aloe vera L.var for gaining aloin is 2 years in leaf(34.16μg/g).And the content of aloin in gel could gain thc highest at the fourth years in the growing period(14.88μg/g) but the content of aloin is low.Through researching on change of polysaccharides of Aloe vera L.var of different time, the result indicates that with extend of Aloe vera L.vat's development,the extent of polysaccharides change,there is apparently different,and the top extent appears in two-year a Aloe vera L.vat(the gel reach 1405mg/L average,the whole leaf reach 709 mg/L average ). In the whole development time,the extent of gel polysaccharides is higher than the whole leaf.Through the experiment,the conclusion is:in the process,the peer can not be removed, and can be added to producing with tissue.In the same way,in the process,the root can not be removed,the harvest time of Aloe vera L.var is two-year,then the higher extent of polysaccharidcs and aloin can be gotten.Aloe vera L.vat can be used as a micros prohibiton in food to prohibition micros pollution. |
