Studies on chemical constituents of Selaginella stauntoniana (II)

Object To study the chemical constituents of whole plant of Selaginella stauntoniana Spring. Methods Column chromatographic technique was employed for the isolation and purification of its constituents; and structurally identified by spectral analysis (IR,UV,MS, 1H-NMR , 13 C-NMR ). Results The compounds were identified from its extract as: 1-monotetracosan (Ⅰ),palmitic acid (Ⅱ),chrysophanol (Ⅲ),physcion (Ⅳ),1-triacontanol (Ⅴ),1-triacontanoic acid (Ⅵ),emodin (Ⅶ). Conclusion All the compounds are found in this plant for the first time;Ⅰ, Ⅲ-Ⅶ are obtained from the plants of Selaginellaceae for the first time.
