A phytochemical investigation on the ethanol extract of green walnut husks (Juglans mandshurica Maxim.) led to the discovery of two previously unknown compounds, along with 19 known compounds. The structures of these 21 compounds were elucidated by extensive analyses of NMR and HR-MS data, and the basis of spectroscopic analysis.
Phytochemical investigation on the ethanol extract of green walnut husks (Juglans mandshurica Maxim.) led to the isolation of two previously unknown compounds, including a macrolide compound (13S)-8-oxo-(9E, 11E)-8-oxo-octadeca-9,11-dien-13-olide (1) and a diarylheptanoid compound 1-(3 '-methoxy-4 '-hydroxyphenyl)-7-(3 '',4 ''-dimethoxyphenyl)heptan-3-one (2), together with 19 known compounds. The structures of these 21 compounds were elucidated by extensive analyses of NMR and HR-MS data, and the basis of spectroscopic analysis.
