The concentrations of TF and some flavonoid compounds
The results obtained from the preliminary analysis of
flavonoid compounds are shown in Table 1. There was a
significant difference between the three locations for TF
production in pandan. Highest value of TF content in
pandan was observed in Bachok (1.87 ± 0.246 mg/g DW)
location followed by klang (1.32 ± 0.211 mg/g DW)
and pontian (1.12 ± 0.177 mg/g DW). In this research,
5 flavonoid compounds were detected and identified
