Embodiment 1

[0032] One, the HPLC-ELSD detection method of gentamicin C component content in a kind of gentamicin procaine vitamin B12 capsule, comprises the following steps:

[0033] (1) Chromatographic conditions and system suitability test:

[0034] Octadecylsilane bonded silica gel was used as filler, Shiseido ACR C18 4.6×250mm 5μm chromatographic column, methanol was used as mobile phase A, 0.02mol / L trifluoroacetic acid was used as mobile phase B, and gradient elution was carried out according to Table 1. The flow rate is 1ml / min, the column temperature is 30°C, the atomization temperature is 70°C, and the air velocity is 1.6SLM. The chromatogram of the gentamicin standard solution should be consistent with the standard spectrum;

[0035]

[0036] (2) Solution preparation:

[0037] Preparation of gentamicin sulfate standard solution

[0038] Take 100mg of gentamicin sulfate standard substance, weigh it accurately, put it in a 10mL measuring bottle, dissolve it with water and dil...

Abstract

The invention belongs to the chemical detection field and especially relates to an HPLC-ELSD detection method of a gentamicin C component content in gentamicin procaine vitamin B12 capsules. The method comprises the following steps of (1) carrying out a chromatographic condition and system suitability test; (2) preparing a solution; and (3) testing and the like. Operation of the method is simple,detection efficiency is high, an error is small, and the detection method is stable; accuracy, precision, specificity, a detection limit, and durability and the like of the method accord with a methodological verification requirement; high practicality is achieved; and the gentamicin C component content in the gentamicin procaine vitamin B12 capsules can be rapidly detected so as to effectively control the quality of the gentamicin procaine vitamin B12 capsules.

Description

technical field [0001] The invention belongs to the field of chemical detection, and in particular relates to an HPLC-ELSD detection method for the content of gentamicin C component in gentamicin procaine vitamin B12 capsules. Background technique [0002] Gentamicin Procaine Vitamin B12 Capsules (formerly known as Gastritis Capsules, also known as Gentamicin Procaine Capsules, hereinafter referred to as "capsules")) is composed of gentamicin sulfate, procaine hydrochloride It is a compound oral preparation composed of factor, vitamin B12 and appropriate amount of auxiliary materials. Among them, gentamicin sulfate is an aminoglycoside antibiotic, which has antibacterial effects on various Gram-negative bacteria, Gram-positive bacteria and Helicobacter pylori, can inhibit Helicobacter pylori, and exert local bactericidal effect in the stomach; Luca is a local anesthetic, which can seal the nerve endings on the damaged mucosal surface, block the stimulation of the lesion to ...
