Abstract
Polypremum procumbens (Buddlejaceae) was found to contain
sorbitol, cornoside, salidroside and conandroside. One collection
of Peltanthera floribunda (Buddlejaceae) contained verbascoside,
two others the cornoside-derived rengyolone (= halleridone). From
Tetrachondra hamiltonii (Tetrachondraceae) was isolated sorbitol,
cornoside and verbascoside. Iridoids were not found in any of the
taxa. The taxonomic significance of the different chemical
constituents is discussed, and the data demonstrate a close
relationship between Polypremum and Tetrachondra. They may also
suggest an inclusion of Peltanthera in Gesneriaceae. These
findings are in concert with recently published chloroplast DNA
sequence data.
