Qualitative and quantitative analysis of phytochemicals of crude extracts of Ageratum conyzoides L. leaves

Abstract

Ageratum conyzoides L., belonging to the family Asteraceae, is an annual herbaceous plant and is an invasive weed. It contains bioactive compounds that are reported to possess therapeutic properties. The species has been studied widely owing to its biological properties and its potential application in medicine and agriculture. It is used in the treatment of burns and wounds, arthrosis, malaria, asthma, leprosy and dermatitis. It also has insecticidal activity against a range of major pests of field crops. Chromatographic analyses have identified pyrrolizidine alkaloids, phenolic acids, coumarin and polymethoxyflavones. The present study was conducted to determine the qualitative and quantitative properties of the crude extracts of the leaves. Extracts were prepared by using petroleum ether, chloroform and methanol solvents. The yield of extract was calculated for all the three solvents and they are studied for qualitative analysis of phytochemical compounds and quantitative analysis. The qualitative phytochemical tests exhibited the presences of alkaloids, carbohydrates, phenols, tannins, steroids, terpenoids, glycosides, saponins, and amino acid. Quantitative analysis suggests the presence of tannins, alkaloids and phenols in the leaves and this can be utilized for further investigations.

One-Pot Synthesis of Silver Nanoparticles Derived from Aqueous Leaf Extract of Ageratum conyzoides and Their Biological Efficacy

“…The earlier research work carried out by Puro et al [17] reported that the phytochemicals present in the aqueous leaf extract of Ageratum conyzoides highly influence the antimicrobial activity, which is in line with the present study. Many research studies have suggested that the plant variety of Ageratum species is found to have excellent biological properties, as it is reported to have various phytochemicals, such as phenols, bromophenols, polysaccharides, tannins, flavonoids, phenolic acids and carotenoids [13][14][15][16]18,19].…”

Phytochemical composition and insecticidal effects of native plant extracts against the mango mealybug, Rastrococcus invadens Williams (Homoptera: Pseudococcidae)

“…Arya et al (2011) andVasantharani et al (2022) reported various biological properties, such as antifungal, cytotoxic, nematicidal, antifeedant and larvicidal activities. These occurring activities could be related to the presence of various phytochemicals, such as bromophenols, polysaccharides, tannins, flavonoids, phenols, phenolic acids and carotenoids (Chandraker et al, 2019;Puro et al, 2018).…”

“…The aim is to highlight the bioactive phytochemical groups involved in the insecticidal activities observed. Quantitative analysis was performed following the standard procedure for phenols (Ainsworth and Gillespie, 2007), flavonoids (Chang et al, 2002) and alkaloids (Puro et al, 2018).…”

Anthelminthic, Anti-Inflammatory, Antioxidant, and Antimicrobial Activities and FTIR Analyses of Vernonia camporum Stem-Bark

“…Medicinal plants and human beings have special relationship for centuries [11][12][13]. Medicinal plants and natural products having pharmacological models have been well thought out as alternative therapy for the treatment of various diseases [14][15][16]. A significant number of presently used antimalarial, antioxidant, anthelminthic, anti-inflammatory, and antitumor agents are molecules identified and isolated from plants or their synthetic or semisynthetic derivatives [17][18][19].…”
