Two new antiallergic cyanoglycosides named rhodiocyanosides A and B were isolated from the Chinese natural medicine "Si Lie Hong Jing Tian" (Shiretsukoukeiten in Japanese), the underground part of Rhodiola quadrifida (Pall.) Fisch. et Mey., together with two new glycosides,
octyl
alpha-L-arabinopyranosyl(1-6)-beta-D-glucopyranoside and gossypetin 7-O-beta-D-glucopyranosyl(1-3)-alpha-L-rhamnopyranoside. Their chemical structures were determined on the basis of chemical and physicochemical evidence. Rhodiocyanosides A and B exhibited inhibitory activity on the histamine release from rat peritoneal exudate cells sensitized with anti-DNP IgE. In addition, rhodiocyanoside A was found to inhibit the
PCA
reaction in rats.

extracts from underground parts and fruits of nine Heracleum taxa (Apiaceae) from Southeastern Europe were statistically analyzed to evaluate their chemosystematic significance. Eight investigated taxa (H. orphanidis and members of H. sphondylium group: H. sphondylium, H. sibiricum, H. montanum, H. ternatum, H. pyrenaicum subsp. pollinianum, H. pyrenaicum subsp. orsinii and H. verticillatum) belong to the type section of the genus. Additionally analyzed taxon, H. austriacum subsp. siifolium, belongs to H. sect. Wendia. Qualitative and quantitative analysis of the essential oils was performed by GC-FID and GC/MS, and of the furanocoumarins by LC/MS. Furanocoumarins were identified using standards and/or based on UV, MS,

H- and ROESY NMR spectra. Multivariate statistics (
PCA
, nMDS, UPGMA) of analyzed metabolites showed that the investigated taxa were grouped according to their taxonomic classification.
PCA
revealed the significance of some monoterpenes and (Z)-falcarinol of the underground parts oils,
octyl
esters of the fruit oils, and most of the total of 12 identified furanocoumarins.
