Klang showed highest concentration of kaempferol followed by Bachok. These kaempferol contents had been greater than those recorded in pegaga, sengkuang, carrot, green chilli and white radish. In other examine, Tolonen et al. identified kaempferol in white cabbages with concentration of 0. 9 mg kg FW, and it was the sole flavonoid observed. Meanwhile, Kim and Lee detected about 0. 1 0. 8 mg g FW of kaempferol contents in green cabbages. In current review kaempferol was not detected in pandan extract from pontian place. Naringin was also detected from pandan extract with considerable concentration. Between studied places Bachok showed highest worth 0. 325 0. 025 mg g DW followed by Klang 0. 223 0. 026 mg g DW. Naringin was not detected from pandan in Pontian place. Zhang et al.
identified rutin in pandan with concentration purchase Trichostatin A of 0. 356 mg 100 g DW. Normally, among identified flavonoid compounds the essential compound determined by concentration from large to very low had been, catechin naringin kaempferol rutin epicatechin. Success imply that catechin is abundant flavonoid compounds in pandan. Figure one demonstrates the HPLC chro matogram of pandan extracts from Bachok location. The concentrations of TP and some phenolic acids Typically, phenolics that possess antioxidant exercise are regarded to be primarily flavonoids and phenolic acids. Phenolic acids are a big class of phenolic compounds, widely happening from the plant kingdom especially in 0. 406 mg g DW and Pontian. A significant variation was observed among Bachok and Klang in TP articles but, variations amongst Klang and Pontian was not major.
Nonetheless, com pared to a few of potent herbs like as Melisa officinalis, Taraxacum officinale, Acorus calamus, Echinacea purpurea, Syzygium aromaticum and Salvia officinalis pandan recorded lowest contents of TP. It really is evident that the total phenolic content material measured from the Folin Ciocalteu strategy isn’t going to give a complete image from the quality or Bafetinib amount in the phenolic compounds while in the plant extracts. In latest analysis 3 phenolic acids which include gallic acid, cinnamic acid and ferulic acid were identified in pandan extracts from 3 areas. The extract of pandan from Bachok exhibited highest value of gallic acid when compared with Klang and Pontian locations. In addition no important distinction was observed amongst Klang and Pontian places for gallic acid production in pandan. As Table two exhibits, amid the studied phenolic compounds cinamic acid was detected from Bachok and Klang areas. Bachok spot repre sent substantial value of cinnamic acid followed by Klang. Cinnamic acid was not detected in pandan extract from Pontian area. Ferulic acid was detected just in pandan extract of Bachok location with value of 0. 281 0. 037 mg g DW.
