Synedrella
nodiflora (L.) Gaertn. (Asteraceae) a dominant invasive weed from Ganeshkhind area
has
affected the phytodiversity of Pune University campus
(M.S., India). Its leaf leachates inhibited seed
germination and seedling growth in test crops like
tomato and brinjal at all the concentrations
indicating their phytotoxic nature. However maximum
inhibition was recorded at higher concentrations
(17.5–20% of original stock solution). The allelopathic
leaf leachates had also adversely influenced
the seedling physiology in both the vegetables. Hence
to investigate its phytotoxic nature, isolation
and characterization of allelochemicals in it, was
undertaken. Leaf samples of Synedrella showed the
presence of a ketone 3-(5-(1-(3-methylpentyloxy)
propyl)-tetrahydro-2-oxofuran-3-yl)-dihydrofuran-
2(3H)-one.
