| 摘 要： | 本文建立了中草药黄芩中黄芩甙、青黛中靛蓝、牡丹皮中丹皮酚、荜茇中胡椒碱的二阶导数差示脉冲极谱的定量分析方法。黄芩、靛蓝、丹皮酚和胡椒碱的化学结构中都含有ＣＯ，在酸性条件下，于滴汞电极上均可发生还原反应生成ＣＯ，并分别于１５５０Ｖ，１３００Ｖ，１６３０Ｖ，０８６０Ｖ（ｖｓＡｇ／ＡｇＣｌ）处出现良好的二阶导数差示脉冲极谱峰。黄芩、靛蓝、丹皮酚和胡椒碱分别在４５×１０５～２７×１０４ｍｏｌ·Ｌ１，３８×１０５～２５×１０４ｍｏｌ·Ｌ１，１０～６０×１０４ｍｏｌ·Ｌ１和７０×１０５～２５×１０４ｍｏｌ·Ｌ１范围内，浓度与其二阶导数差示脉冲极谱峰幅值呈极为显著的线性关系（Ｐ〈００１），检测限分别为９０×１０８ｍｏｌ·Ｌ１，８４×１０９ｍｏｌ·Ｌ１，９２×１０９ｍｏｌ·Ｌ１和８７×１０９ｍｏｌ·Ｌ１。方法简便、快速、灵敏，结果准确。
