Showing papers on "Isopimpinellin published in 1970"

TL;DR: In this paper, seven coumarins were isolated from the roots of Ruta pinnata L. fil., including xanthyletin, luvangetin, isopimpinellin, sabandin and thamnosin.

TL;DR: Sphondin is the principal furanocoumarin of Heracleum lanatum leaves; pimpinellin, isopimpinella, bergacetoxin, xanthotoxin, isobergapten, psoralen and angelicin were also identified as discussed by the authors.

TL;DR: In this paper, it was shown that carbon side-chain attachment precedes further oxygenation of umbelliferone in furanocoumarin biosynthesis, supporting the theory that it is a major intermediate in bergapten formation.
