Article abstract of DOI:10.1016/0031-9422(91)83051-L

Three new natural lignans, methyl deoxypodophyllotoxinate, podophyllotoxinic acid and 7β-hydroxydihydrosesamin, 11 known lignans and two cinnamyl alcohols were isolated and identified from a chloroform extract of Juniperus thurifera leaves.Assignment of the (13)C NMR spectrum of β-methyl peltatin B was also performed through direct and long-range heteronuclear 2D NMR analysis, amending previous assignments.
