Known amounts of the standard compounds were added either to the dry powdered root material, followed by extraction or were applied on the polyamide column together with the tincture.

The flowers have glands called elaiophores which produce a lipid which is collected by bees of the genus Centris as they pollinate the flowers. The topical anti-inflammatory properties of the secondary metabolites were comparable to the drug indomethacin ID 50 value 0. Highest deviations within the root samples were found for compounds 5 and 12 with contents ranging from 0.
Individual stock solutions of standard compounds were prepared in methanol. Attempts to improve the resolution with the aid of additives, such as tetrahydrofuran, 1- and 2-propanol or tert-butylmethyl ether, or a variation of temperature showed no effect.
Stuppner, Lignan derivatives from Krameria lappacea roots inhibit acute inflammation in vivo and pro-inflammatory mediators in vitro, J Nat Prod. Separation was possible by changing the stationary phase from the phenyl-hexyl material to a RP column material, but as highlighted before this made a separation of compounds 11 and 12 impossible. Antioxidant and photoprotective activity of a lipophilic extract containing neolignans from Krameria triandra roots.

The biological action of rhatany is caused by the astringent rhataniatannic acidwhich is similar to tannic acid. Interestingly, root sample RR-1 showed a higher content of all benzofurans, except for compounds 6and The initial screening experiments stationary phases with RP, RP, ether-linked phenyl, phenyl-hexyl column material clearly showed that the stationary phase had to be a phenyl-hexyl column, since this phase exclusively enabled the baseline separation of ratanhiaphenols II 11 and I 12which represent the most prominent constituents in Ratanhiae radix.
Suitability of the developed method for the quantification of the major lignan derivatives in Ratanhiae radix and Tinctura Ratanhiae can be deduced from several analytical parameters. Support Center Support Center.
The extract was evaporated to dryness yielding kraeria All other HPLC parameters were maintained. Method development The major problem in the development of a HPLC method for the simultaneous detection of all active lignan derivatives was the structural similarity of the analytes.
This validated assay will be a useful tool for quality control of the plant material and its preparations, focusing on the compound class of lignan derivatives. In the case of root samples, different solvents methanol, acetone, DCM and mixtures thereof and extraction procedures sonication, ASE extraction were evaluated. Studies on Ratanhiae Radix II. Quality of root samples of K. This page was last edited on 21 Novemberat Preliminary tests were performed in order to determine optimum sample preparation conditions for the root as well as the tincture samples.

Lappacfa root bark contains an almost insoluble free red substance called ratanhia red. Open in a separate window. The quality of those complied with the Austrian Pharmacopoeia. Views Read Edit View history. Proanthocyanidins from Krameria triandra root. One prominent constituent of the investigated extracts 3-formyl 4-hydroxyphenyl E -propenylbenzofuran; compound 7an additional lignan derivative, was isolated in course of the present study.
