Chemical composition, insect antifeeding, insecticidal, herbicidal, antioxidant and anti-inflammatory potential of Ardisia solonaceae Roxb. root extract

The objectives of this research were to investigate the qualitative and quantitative analysis of Ethyl Acetate Root Extract of Ardisia solanacea Roxb. (EREAS) and estimation of its biological activities. Phytochemical screening of EREAS showed the abundance of total phenolics, flavanoids, ortho-dihydric phenols, alkaloids, diterpenes and triterpenes etc. The quantitative analysis of EREAS was also carried out by GC/MS and α-amyrenone (13.3%) was found to be the major component. Antifeeding activity monitored through no choice leaf dip method against Spilosoma oblique. The results revealed dose and time dependent antifeeding activity, where the 100% mortality was observed signifying the intense insecticidal activity. The herbicidal activity of extracts was evaluated against the Raphanus raphanistrum seeds. Accordingly, EREAS showed effective herbicidal activity in terms of inhibition of seed germination, coleoptile length and the radical length. Evaluation of antioxidant activity was performed via DPPH radical scavenging, reducing power and metal chelating of Fe2+ activities. EREAS possessed potential antioxidant property and revealed good anti-inflammatory activity.
