Abstract

The invention discloses a method for rapidly detecting monosaccharide in tulip tree plant nectar and belongs to the field of chemical analysis. Compared with a traditional method for detecting components of plant nectar through high-performance liquid chromatography, the method has the advantages of being rapid, efficient, small in sample size and low in cost. An alpha-naphthylamine derivation method is adopted in the method, a Na2B4O7.10H2O aqueous solution with the pH value being 9.5 serves as a background buffer solution, under the conditions of 20 kv voltage and 0.5 psi of sample feeding conducted for 8 s, glucose and fructose in the nectar can be separated within 20 min, and the content of the glucose and the fructose is measured according to an external standard method.

Description

technical field [0001] The invention relates to the technical field of chemical analysis, in particular to using capillary electrophoresis to separate and detect the contents of glucose and fructose in the nectar of Liriodendron genus plants. Background technique [0002] There are two existing species of Liriodendron in Magnoliaceae, one is Liriodendron (L.tulipifera Linn.); the other is Liriodendron [L.chinense (Hemsl.) Sarg.]. Liriodendron genus has bisexual flowers, cup-shaped, open at the same time as the leaves or later; 9 perianth segments, 3 green sepals on the outer ring, spreading outwards; 6 petals on the inner two rings are erect. The flower color of Liriodendron tulipiflora is very different from that of Liriodendron tulipifera. The flowers of Liriodendron tulipifera are yellow-green with yellow vertical stripes near the base, while the flowers of Liriodendron tulipifera are emerald green with orange-yellow or orange-red bands near the base. The nectar secretio...
