Antitermite Activities of C. decidua Extracts and Pure Compounds against Indian White Termite Odontotermes obesus (Isoptera: Odontotermitidae)
Figure 1
Pure compounds obtained from C. decidua after solvent fractions being eluted and purified by column chromatography. Compounds CDS3 (25 mg) and CDS8 (50 mg) were identified as triacontanol and 2-carboxy-1,1-dimethylpyrrolidine. While compound CDS2 is characterized as heneicosylhexadecanoate. The column was prepared in petroleum ether using silica gel (60–80) as an adsorbent and eluted with petroleum ether/chloroform, chloroform, chloroform/methanol mixtures of increasing polarity. CDF1 was isolated (15 mg) from flowers from the chloroform fraction of the extract. It was identified as 6-(1-hydroxy-non-3-enyl) tetrahydropyran-2-one and is colorless.
