Beschreibungen/Notizen

• Chloroform and methanol fractions of an ethanol extract of Spatoglossum asperum showed antifungal activity against the highly destructive plant pathogen, Macrophomina phaseolina while the n‐hexane fraction showed activity against Rhizoctonia solani and Fusarium solani. n‐Hexane and methanol fractions also showed nematicidal activity against the plant parasitic nematode, Meloidogyne javanica. Column chromatography of the ethanol extract of seaweed yielded oily fractions named SA‐I to SA‐VI. GC‐MS data of these oily fractions showed the presence of various fatty acid esters. Some of these oily fractions exhibited strong antifungal and nematicidal activities. Oily fractions of S. asperum also showed hypolipidaemic activity in normal, triton‐induced and high fat diet‐induced hyperlipidaemic rats without producing any ill effect on cardiac and liver enzymes.
