Description / Table of Contents:
Alkaloids from Rhamnaceae, XIX1). - Mucronine-E, -F, -G, and -H as well as Abyssenine-A, -B, and -C, New 15-Membered Cyclopeptide Alkaloids**)In addition to the known alkaloids mucronine-A, -B, -C2), and -D3), four new peptide alkaloids, mucronine-E, -F, -G, and -H have been isolated from the crude base of Zizyphus mucronata Willd. and their structures 1-4 elucidated4). - The bark of Zizyphus abyssinica Hochst. ex A. Rich. contains not only the mucronines-A, -B, and -C but also the alkaloids abyssenine-A, -B and -C5) (5-7), which belong to the same structural type as 1-4 and are therefore also described here.
Notes:
Aus dem Rohbasengemisch von Zizyphus mucronata Willd. wurden neben den bereits beschriebenen Mucroninen-A, -B, -C2) und -D3) vier neue Peptidalkaloide Mucronin-E, -F, -G und -H isoliert und deren Strukturen 1-4 ermittelt4). - Die Rinde von Zizyphus abyssinica Hochst. ex A. Rich. enthält neben Mucronin-A, -B und -C noch die Alkaloide Abyssenin-A, -B und -C5) (5-7), die im Strukturtyp den Mucroninen-E bis -H entsprechen und daher mit diesen zusammen beschrieben werden.
