Anti-inflammatory and antinociceptive activity of coumarins from Seseli gummiferum subsp. corymbosum (Apiaceae).[Pubmed:19323267]
Z Naturforsch C. 2009 Jan-Feb;64(1-2):56-62.
n-Hexane and ethyl acetate extracts as well as coumarin derivatives obtained from the n-hexane extract of the aerial parts of Seseli gummiferum Pall. ex Sm. subsp. corymbosum (Boiss. & Heldr.) P.H. Davis (Apiaceae) were evaluated in vivo for their anti-inflammatory and antinociceptive activities. The n-hexane and ethyl acetate extracts of the species were shown to possess significant inhibitory activity against the carrageenan-induced hind paw edema and p-benzoquinone-induced writhing models in mice. Among the isolated coumarin derivatives; (-)-(3'S,4'S)-3'-acetoxy-4'-isovaleryloxy-3',4'-dihydroseselin (1), (-)-(3'S,4'S)-3'-acetoxy-4'-angeloyloxy-3',4'-dihydroseselin (2), (+)-(3'S,4'S)-3'-hydroxy-4'-angeloyloxy-3',4'-dihydroseselin (d-Laserpitin) (3), (-)-(3'S,4'S)-3'-angeloyloxy-4'-hydroxy-3',4'-dihydroseselin (4), and osthole (5), only the 3'-acetoxy derivatives 1 and 2 were found to possess potent antinociceptive and anti-inflammatory activities, per os, without inducing any apparent acute toxicity as well as gastric damage, while all other compounds and extracts were found to be ineffective in the TPA-induced mouse ear edema model assay.
Application of stepwise gradients in counter-current chromatography: a rapid and economical strategy for the one-step separation of eight coumarins from Seseli resinosum.[Pubmed:23992840]
J Chromatogr A. 2013 Oct 4;1310:66-73.
The targeted purification of compounds with a broad polarity range from traditional medicinal plants is a big challenge for counter-current chromatography (CCC). Gradient elution was introduced in CCC to address this problem. However, once a suitable solvent system is selected, the separation process requires optimization of operational parameters. The present study was conducted to optimize various operational parameters to integrate the flow rate and solvent gradients for the rapid isolation of eight coumarins from Seseli resinosum in a single run. An increase in the system temperature from 15 degrees C to 35 degrees C increased the stationary phase retention and solubility of the sample, whereas the operation time and viscosity of the system were decreased. The high purity of each compound was ensured by collecting the fractions from the main peaks while all the shoulder peaks were mixed and separated under the same conditions with semi-preparative CCC. GC-FID was used to analyze the components of each phase, which was prepared without presaturation to save the time and solvent consumption. Finally, eight coumarins were purified, including (1) d-Laserpitin, (2) (3'S,4'S)-3'-angeloyloxy-4'-hydroxy-3',4'-dihydroseselin, (3) (+)-samidin, (4) (3'S,4'S)-3'-acetoxy-4'-angeloyloxy-3',4'-dihydroseselin, (5) deltoin (6), calipteryxin, (7) (3'S,4'S)-3',4'-disenecioyloxy-3',4'-dihydroseselin, and (8) (-)-anomalin. The present technique has successfully accomplished the goal of one-step separation of these compounds with high purity and recovery in an economic and time efficient manner.
