7-feruloylloganin: an iridoid glucoside from stems of Lonicera insularis.
A new iridoid glucoside, 7-feruloylloganin (1), was isolated from stems of Lonicera insularis, along with six known lignans including (-)-pinoresinol, 9alpha-hydroxypinoresinol, balanophonin, erythro-1-(4-hydroxy-3-methoxyphenyl)-2-[4-[2-formyl-(E)-vinyl]-2-methoxyphenoxy]-propane-1,3-diol, threo-1-(4-hydroxy-3-methoxyphenyl)-2-[4-[2-formyl-(E)-vinyl]-2-methoxyphenoxy]-propane-1,3-diol and buddlenol A. The structure of 1 was determined by analyses of 2D NMR (1H-1H COSY, HMQC and HMBC) and HRFABMS.
