Four new oligosaccharides (1-4), one new pregnane glycoside (5), and one new cardiac glycoside (6) were isolated from the roots of Periploca forrestii Schltr. (Asclepiadaceae), a traditional Chinese medicine used for the treatment of rheumatoid arthritis and wounds. Their structures were characterized on the basis of extensive analysis of NMR (1H, 13C NMR, 1H-1H COSY, HSQC, HMBC, TOCSY and ROESY) spectra.
从用于治疗类风湿性关节炎和伤口的传统中药黑骨藤（萝摩科）的根中分离出四种新的寡糖（1-4）、一种新的孕烷糖苷（5）和一种新的强心苷（6）。通过对核磁共振（1H、13C NMR、1H-1H COSY、HSQC、HMBC、TOCSY和ROESY）光谱的广泛分析对它们的结构进行了表征。
