title: Isolation and structure of korolkoside, a bis-iridoid glucoside from Lonicera korolkovii.
abstract: A new bis-iridoid glucoside, korolkoside (1), was isolated from Lonicera korolkovii, and its structure and stereochemistry were determined by spectroscopic analysis and chemical derivatization. Korolkoside (1) consists of two secologanin moieties that are connected by an acetal linkage.
