Mh. Park et al., ABSOLUTE-CONFIGURATION OF A CYCLOPEPTIDE ALKALOID, SANJOININE-G1, FROM ZIZYPHUS-VULGARIS VAR SPINOSUS, Phytochemistry, 43(3), 1996, pp. 701-704
A new cyclopeptide alkaloid, sanjoinine-G1, has been isolated from the
seeds of Zizyphus vulgaris var. spinosus. The structure and absolute
configuration has been established by spectroscopic analysis and the c
ircular dichroism exiton-coupling method, as N-[(S)-(N',N')-dimethylph
enylalanyl]-cyclo[O-(2S, l-(S)-leucyl-(2-mino-(1R)-hydroxyethyl)-p-phe
nyl]. Copyright (C) 1996 Elsevier Science Ltd
