目的 :通过测定石榴花、蒂、皮的微量元素含量、对照薄层层析及紫外吸收光谱 ,探讨其化学成分的相对含量及差异。 方法 :分别测定石榴花、蒂、皮微量元素含量 ,并作对照 ;对 3个样品分别在两种不同展开体系中进行对照薄层层析 ;分别测定其紫外吸收光谱。 结果 :石榴的花、蒂、皮 3部分的微量元素含量相差较大 ,其中花和皮的微量元素含量相对较高 ,而花中更为明显。不同展开体系的对照薄层层析显示石榴花展开后斑点较多 ,皮次之 ,蒂最少。紫外吸收光谱图在约λ 2 2 0 nm及λ 2 6 0 nm的两个主要吸收峰的吸收值 ,亦为石榴花的最大 ,皮的次之 ,蒂的最小。 结论 :实验结果预示石榴花中的化学成分较为丰富 ,有望进一步深入研究。
OBJECTIVE : To determine the relative contents and differences of chemical constituents in the pomegranate flower, pedicle, and skin by means of thin layer chromatography and ultraviolet absorption spectroscopy. Methods: The contents of trace elements in pomegranate flowers, pedicles and skins were determined and used as controls. Three thin-layer chromatograms were performed in two different deployment systems. The ultraviolet absorption spectra were measured. Results: The content of trace elements in flower, peduncle, and peel of pomegranate differed greatly. Among them, the content of trace elements in flower and bark was relatively high, but it was more obvious in flowers. The control TLC of different development systems showed that the pomegranates had more spots after they were unfolded, and the skin had the least pedicles. The absorption values of the two main absorption peaks at about λ 2 2 nm and λ 260 nm for the UV absorption spectra are also the largest for the pomegranate flower, followed by the skin, and the smallest for the pedicle. Conclusion : The experimental results indicate that the chemical composition of pomegranate is more abundant and is expected to be further studied.
