METHODS AND RESULTS:
From the extract of Saururus cernuus two toxic principles, manassantins A and B and a related substance, Saucerneol, were isolated.
CONCLUSIONS:
They have novel dineolignan or sesquineolignan type structures. Although toxic, manassantin A showed potential neuroleptic activity. | | Advanced Materials Research,2011, Vols. 393-395 | | Studies on Chemical Constituents from the Aerial Parts of Saururus chinensis.[Reference: WebLink] | To investigate into the active chemical constituents of Sanrurus chinensis．
METHODS AND RESULTS:
Repeated silica gel column chromatography was used in the isolation and purification; determination and spectral analysis were adopted to identify the chemical structures． Nineteen chemical compounds were isolated from the aerial parts of Saururus chinensis and identified as sauchinone (1),sauchinone A (2), licarin B (3),saucernetin(4), Saucerneol I(5), Kaemferol(6), Kaemferol- 3-O-rhamnopyranosyl(1→6)glucopyranoside(7), luteolin(8), quecretin (9), quecretin-7-O-β- D-glueopyranoside (10), quecretin-7-O -α-D-glueopyranoside (11), ursolic acid(12), ellagic acid(13), p-hydroxybenzoic acid(14), gallic acid(15), 3,4-dihydroxybenzoic acid (16) , caffeic acid(17), stearic acid (18) and β-sitosterol (19). |
