A method for detecting galantamine in sudden laughter

Abstract

The invention discloses a method for detecting galantamine in lycoris aurea, and relates to plant sample handling, preparation of a nanogold printing electrode sensor and electrochemical detection. According to the method, the nanogold-modified printing electrode sensor is adopted to fully absorb in a sample extracting solution, then the nanogold printing electrode sensor is subjected to differential pulse voltammetry scanning to measure current values at oxidation peaks, within a detectable range, the content of the galantamine in the lycoris aurea absorbed by the nanogold printing electrodesensor is in a linear relation with the current intensities at the oxidation peaks, and according to a working curve, the content of the galantamine in the detected lycoris aurea can be calculated. The method has the advantages that the nanotechnology and the silk-screen printing technology are combined by the prepared nanogold printing electrode sensor, sensitivity, in galantamine concentration detection, of the sensor can be improved remarkably, and the minimum limit of detection of the sensor can reach to 0.013 microns.

Description

technical field

[0001] The invention relates to a method for detecting galantamine in herbaceous flowers of the genus Lycoris, in particular to a method for detecting galantamine by a nano-gold modified printing electrode. Background technique

[0002] Hudixiao is a perennial herbaceous flower of the genus Amaryllis. It grows mostly in a cool and dark place. It is warm in nature, flat and sweet in taste, and has the effects of reducing swelling, relieving pain, dispelling toxins, and inducing vomiting. Galantamine is a secondary metabolite alkaloid of Hudixiao, which is mainly distributed in its bulbs. It is recorded in the "Chinese Pharmacopoeia" that the injections and tablets of galantamine hydrobromide can be used to treat nervous system disorders. Sensory or movement disorders caused by it, including the treatment of sequelae of poliomyelitis, myasthenia gravis, and intestinal paralysis, as well as anti-curare drugs and wake-up agents after surgical anesthesia, etc. In...
