Article abstract of DOI:10.1016/0031-9422(82)85180-7

The plant growth regulating substances, pimpinellin, isopimpinellin, bergapten, isobergapten, vaginidiol, sphondin, scopoletin, umbelliferone, ferulic acid, p-coumaric acid and apterin were isolated from root of Heracleum lanatum.Scopoletin and umbelliferone were highly inhibitory to the growth of Chinese cabbage seedlings, and bergapten and sphondin to the growth of hypocotyl cuttings of cucumber seedlings.Bergapten and sphondin accelerated root formation of cucumber hypocotyl cuttings. - Key Word Index - Heracleum lanatum; Umbelliferae; coumarins; furanocoumarins; phenolic compounds; growth inhibitor; root formation.
