  • Title: Cyclopeptide alkaloids from stems of Paliurus ramossisimus.
    Author: Lee SS, Su WC, Liu KC.
    Journal: Phytochemistry; 2001 Dec; 58(8):1271-6. PubMed ID: 11738421.
    Abstract:
    Three 13-membered cyclopeptide alkaloids, paliurines G, H and I, together with six known alkaloids, nummularine H, daechuine-S3, paliurines A-C and F, were isolated from the stem of Paliurus ramossisimus by a combination of centrifugal partition chromatography and preparative TLC. Their structures were characterized and established on the basis of spectral analysis. A preliminary study indicated that nummularine H could shorten the methohexital induced sleeping time.
