A terpenoid, 3-oxo-(20S, 24S)-epoxydammarane-19,25-diacetate (CP-1) isolated from the chloroform extract of barks of Caesalpinia pulcherrima was characterized on the basis of spectral data coupled with chemical evidence. The compound showed significant antibacterial activity against a number of pathogenic bacteria and prominent antifungal activity against a few fungi. The minimum inhibitory concentration (MIC) values against Bacillus cereus and Shigella dysenteriae were 16 μg ml-1 and 32 μg ml-1 respectively. The compound was found cytotoxic against brine shrimp and LC50 value was 8.41 μg ml-1. These findings suggested for further clinical trial. |

Field experiment was conducted with three cultivated varieties of C. capsularis and of C.
olitorius to study the performances of yield and yield contributing characters at four harvest
stages, 50, 70, 90 and 110 days. Wide ranges of co-efficient of variation was observed in
each harvest stage in three characters. Two morphological characters, plant height and base
diameter have been used for selection of jute plants with higher fibre yield. However, for
selection purpose, these method needs a long time to wait until flowering. An early
selection method was developed by studying morphological components and fibre yield.
Using these methods breeders can do their selection process earlier prior to maturity e.g.,
at 70 or 90 days age of the plants. This could enable jute breeders to discard most of the
segregating population for higher fibre yield at an earlier stage, which could save
considerable amounts of time and labour. |
