摘要

在本實驗中，作者曾用柑果苷，3'-甲基，3'-乙基，3'-丁基，3'-苄基柑果苷及其柑果素，分別在酒精溶液中及三氯化鋁酒精溶液中，測定其紫外線吸光度最高點的波長位置，結果，在酒精溶液中，上述之柑果苷，3'-烴基柑果苷，柑果素及3'-烴基柑果素的紫外線吸光度最高點在波長286至288mμ處，而在三氯化組酒精溶液中，則均移至波長306至310mμ處，此即證明其同三氯化鋁化合產生一螯環化合物也，作者曾用電流滴定法(amperometric titration法)，在酒精水溶液中，用AlCl_3酒精滴定液，測定3'-烴基柑果苷，柑果素及3'-烴基柑果素，發現其同三氯化鋁分子之比例為1 : 1，此法簡捷準確，可作柑果苷衍生物定量分析之用。

In this experiment the ultraviolet absorption spectra of various hesperldins were measured in alcohol and in alcoholic AICl_3 solution. These included 3'-methyl, 3'-ethyl, 3'-butyl, 3'-benzylhesperidins and their respective hesperetin derivatives. In alcohol solution a peak of absorbance was observed to occur between the wave length 286-288mμ. . While in alcoholic AICl_3 solution the peak shifted to the wave length 306-310 mμ. This was interpreted that the chelate compounds were formed among the 3'-alkylhesperidins or 3'-alkylhesperetins with AICl_3. The author went on to apply this result to determine the said compounds by means of amperometric titration in aqueous alcohol solution, and found the mole ratio with AICI_3 to be 1: 1. It was commented that this simple but precise method was practical and feasible in quantitative analysis of the 3'-alkylhesperidins and 3'-alkylhesperetins.
