Abstract

|
|
Objectives : This research was performed to analyze the components in the different parts of Lythrum salicaria L. and
to compare which parts of L. salicaria L. are appropriate for food development.
Methods : L. salicaria L. was extracted in 20% EtOH at 100 ℃ for 4 hours. Cytotoxicity was investigated in 3T3-L1
cells after treatment of 10-500 μg/ml L. salicaria L. Total polyphenol content (TPC) was estimated using 1 N Folinciocateu reagent. 2,2-Diphenyl-1-picryhydrazyl (DPPH) radical scavenging activity was estimated using DPPH reagent
and gallic acid. The chemical composition was analyzed by high-performance liquid chromatography (HPLC). 1)
Results : The half maximal inhibitory concentration (IC50) in the extracts of the whole plant, aerial parts, and root
parts was 376 μg/ml, over 500 μg/ml, and 140 μg/ml, respectively. The TPC in the extracts of the whole plant,
aerial parts, and root parts was 527.1 mg/g, 422.6 mg/g, and 781.1 mg/g, respectively. There was no statistical
significance in vitexin, TPC, DPPH activity between the aerial parts and the root part of L. salicaria L.
Conclusions : There were no significant differences in the content of components and antioxidant activity in the
aerial parts compared to those in the whole plant of L. salicaria L. Furthermore, the root parts had low extract
yield, cytotoxicity, and quality control problems, therefore our results suggest that the use of the aerial part of L.
salicaria L. would be the most appropriate for food development.
