Known determinations of the absolute configuration of guaianolides were collected and found to be few. The absolute configurations of guaianolides rest on the assumption that 7-H always has alpha-orientation. For matricin, only the relative configuration was determined. On the basis of a detailed
Yarrow (Achillea millefolium L. s.l.) is traditionally used against inflammatory and spasmodic gastrointestinal complaints, hepato-biliary disorders, as an appetite enhancing drug, against skin inflammations and for wound healing due to its antiphlogistic, choleretic and spasmolytic properties. The
Five guaianolides, including two pairs of isomers, from a Hungarian taxon of the Achillea millefolium group were characterized analytically. Different chromatographic systems on TLC and HPLC were developed for the analysis of these compounds. TLC of leucodin, 8alpha-angeloxy-leucodin, achillin,
Chamazulene carboxylic acid (1) is a natural profen with anti-inflammatory activity and a degradation product of proazulenic sesquiterpene lactones, e.g., matricin. Both 1 and proazulenes occur in chamomile (Matricaria recutita), yarrow (Achillea millefolium), and a few other Asteraceae species. It
Four polar guaianolides, 8alpha-angeloxy-2alpha,4alpha, 10beta-trihydroxy-6betaH,7alphaH, 11betaH-1(5)-guaien- 12,6alpha-olide; 8alpha-angeloxy-1beta,2beta:4beta,5beta-diepoxy- 10beta-hydroxy-6betaH,7alphaH,11betaH-12,6alpha-guaianolide; 8alpha-angeloxy-4alpha, 10beta-dihydroxy-2-oxo-6betaH,
The genus Achillea consists of about 140 perennial herbs native to the Northern hemisphere. Traditional indications of their use include digestive problems, liver and gall-bladder conditions, menstrual irregularities, cramps, fever, wound healing. The Commission E approves its internal use for loss
A method for the micropropagation of Achillea asplenifolia VENT. (Asteraceae) is described. Axillary shoots regenerated from nodal explants of adult plants could be stimulated to multiple shoot formation on the basal medium of Murashige and Skoog (1962), supplemented with different cytokinins. The
