| description | This study was performed to identify the chemical composition of essential oils extracted from root, stem
and leaves of the three Piper spp. which are Piper sp1, P. betle and P. sarmentosum. The essential oils was
extracted by using hydrodistillation and then subjected to gas chromatography-flame ionization detector for
analysis purpose and Kovat indices calculation. The percentage yield of essential oil from the root, stem and
leaves were generally ranged from 0.3% - 2.47% (v/w) and the result showed that P. sarmentosum give the
highest percentage yield of essential oil. For overall, there are 102 components detected from the root part of
Piper spp., 98 components from stem part and 75 components from leaves part. These components include
the 25 terpenes compound, 46 ester, 57 aldehyde and ketone, 47 alcohol, 4 acids and 39 others. The close
relationships between these species were analyzed by using Hierarchical Cluster Analysis and the dendogram
produced showed the similarities in term of chemical composition from Piper spp. Toxicity test showed that
P. sarmentosum was the most toxic substance for root part with LC50 of 55.06 µg/mL. While, for the both of
stem and leaves part, Piper sp1 showed the most toxic potential towards the larvae with LC50 of 66.24 µg/mL
and 56.55 µg/mL respectively. Antitermite activity of the Piper spp. showed that P. sarmentosum was the
most toxic against the termites for all parts. |
