Growth, Yield and Phytochemical Constituents of Arctium lappa L. in Response to Phosphorous and Potassium Fertilizers Application

Abstract

Burdock (Arctium lappa L), is a medicinal plant with many therapeutic values but its cultivation practice is given less attention causing pressure on its wild population. A two separate complete randomized design pot experiment with five treatments of phosphorous (Triple superphosphate 20%) at five levels (140, 210, 280, 350 and 420 kg/ha) and potassium (Potassium Chloride 50%) at five levels (210, 315, 420, 520 and 630Kg/ha) with a basal application of Nitrogen fertilizer (Urea,160 Kg/ha) replicated four times was conducted. Fertilizer treatments were split into two equal doses at seedling transplant and four weeks after transplant. Data on growth and yield were collected and analyzed using SAS software. Test results were significant (p<0.05) in growth parameters in response to phosphorous and the number of leaves in potassium treatments. However, there was no significant difference (p>0.05) on yield parameters due to fertilizer application except for root length. Phytochemical screening indicates the presence of Tannins, flavonoids, Terpenoids, glycosides, and phenols across treatments. Crude lipid and ash content were not significant (p>0.05) but there was a significant difference (p<0.05) on crude fibre content in response to fertilizer treatments.n.

A platinum nanopstructer electrode with an iodine coating is used to measure the electrochemical behavior of arctigenin using cyclic voltammetry

“…However, there are only a few analytical methods now available for arctigenin, including HPLC, LC-MS/MS, fluorescence, UPLC-ESI-MS/MS, and HPLC-UV [7][8][9][10][11]. Arctigenin electrochemical studies and electroanalytical methods have a large linear range, great sensitivity, and simplicity [12].…”
