    摘要： A reagent for determining a-amylase activity, comprising a maltooligosaccharide derivative of the following formula ##STR1## (wherein either one of R.sub.1 and R.sub.2 is .beta.-galactopyranosil and the other is hydrogen, R.sub.3 is a group bonded to the reducing terminal glucose via a bond cleavable by .alpha.-amylase, which becomes a measurable substance upon cleavage of the bond, and n is an integer of 0-2), which does not comprise adjuvant enzymes; and a method for determining .alpha.-amylase activity which comprises use of the reagent. The reagent of the present invention does not require use of any adjuvant enzyme and is stable since the substrate is not exposed to the decomposition by an adjuvant enzyme. The substrate used in the present invention has high affinity for .alpha.-amylase. Thus, the reagent and the determination method of the present invention make it possible to determine .alpha.-amylase activity with high sensitivity.

    摘要： A quercetin-containing colorant which has as an effective component a quercetin included by cyclodextrin. Effective use thereof as a colorant is possible by imparting thereto resistance against light, heat and chemicals to quercetin which is a flavonoid yellow substance. The colorant may be added to various food products for use of quercetin as a stable coloring matter.

    摘要： There is provided an unbranched cyclodextrin or a branched cyclodextrin inclusion complex of taxol. The complex is produced by adding an unbranched cyclodextrin of a branched cyclodextrin to taxol at a molar ratio of 1-20 times with respect to taxol. A method is provided for the improvement of the solubility of taxol in water by adding an unbranched cyclodextrin or a branched cyclodextrin thereto at a molar ratio of 1-20 times with respect to taxol. The solubility of taxol in water is improved by the present invention. A cyclodextrin inclusion complex of taxol according to the present invention serves to make taxol more easily absorbed when administered to a cancer patient, which is beneficial to cancer patients and the physiological effects of taxol may therefore be more effectively induced.
