摘要
建青黛为一种道地药材,其原植物为马蓝Baphicacanthus cusla(Nces)Bremek。本研究电子探针显微观察表明建青黛呈矿质状微粉未,颗粒的粒径约为10~100μm;X-射线能谱扫描分析(X-ray EDS)结果表明:青黛的元素构成(Mg,Al,Si,P,S,Ca,Mn,Fe)是相对稳定和有特征性的,主体元素为Ca(相对含量达76.9%~82.6%)。电感耦合高频等离子体发射光谱法(ICP-AES)分析结果表明:其钙(Ca)、镁(Mg)、铁(Fe)、钾(K)、锂(Li)和锰(Mn)等元素含量含量分别为33.25%、3.97%、0.77%、0.54%、0.19%和0.14%。建青黛呈现特定的红外光谱图谱,并具有相对稳定的碳酸根特征性强吸收峰(1460.80~1461.28 cm^-1),在873.75~873.97 cm^-1处均有一较强的吸收峰,3422.92~3434.38 cm^-1处也均有一较宽的吸收峰。
(Jian) Indigo naturalis is a kind of authentic and superior Chinese medicinal materials, and its original plant is Baphicacanthus cusla (Nees) Bremek, produced in Xianyou county of Fujian. In this paper, micro-morphology of (Jian) indigo naturalis observed by the electron probe,show as mineralold micro-particle with 10 - 100 μm granularity. By X-ray EDS (energy dispersive spectroscopy), it showed that the dements composition were oppositely steady, consisted of Mg, AI, Si, P, S, Ca, Mn and Fe, and with a characteristic principal element Ca ( relative contents is 76.9% - 82.6% ).The contents of Ca,Mg,Fe,K,Li and Mn were respectively 332.5 mg/g(33.25% ) ,39.7 mg/g(3.97% ), 7.7 mg/g(0.77% ) ,5.4 mg/g(0.54% ) ,1.9 mg/g(0.19% ) and 1.4 mg/g(0.14% ) ,analysed by ICP-AES (Induetively coupled plasma atomic emission spectgrometry). (Jian) Indigo naturalis was shown specific infrared spectroscopy, with an charactenstlc absorption band of CO3 at 1460.80 - 1461.28 cm^-1 ,moreover,obvious absorb peaks were also steadily appeared at 873.75 -73.97 cm^-1 and 3422.92 -3434.38 cm^-1.
