Phytoconstituents, Pigments , G.C.M.S. Analysis and Allelopathy Effect of Alternanthera Ficoidea (L.) P. Beauv

Abstract

Objective: The aim was to investigate phytoconstituents, composition of pigments, gas chromatography mass spectrometry (GCMS) and allelopathy of Alternanthera ficoidea (L.) P. Beauv. Methods:Qualitative phytochemical analysis was carried out by the method of Paech and Tracey using five different solvent systems (D.W., ether, chloroform, ethanol, and methanol). Methanol leaf extract of this plant was analyzed using GCMS. Chlorophylls, carotenoid, and polyphenols were estimated by following standard methods. Allelopathy effect was studied using leaf leachets on seeds of jowar and mung. Result and Conclusion:Investigation of above parameters in A. ficoidea showed presence of large amount of pharmaceutically important phytochemicals like tannins, saponins, phytols, carotenoids, xanthophylls and polyphenols. It indicates that this weed can be used in herbal medicines and dietary supplements. Since this weed is showing allelopathy effect it should be eradicated from fields before it spreads and occupies the place meant for crop plants.

A Preliminary Study on Anti-Mycobacterium, Anti-Candida Activity and Morphological Clustering of Fifteen Folk Medicinal Plants of Assam, India

“…In this experiment, the plants . Similarly, the bioactive molecules and chemical constituents of these species were also reviewed where Saikia et al, 2020 showed abundance of (-)-Isoledene, (±)-Debromofliformin, δ-Cadinene, t-Caryophyllene in the floral essential oil of Mikania micrantha (M. micrantha) which exhibited cytotoxicity with IC 50 <6 µg/ ml against HeLa and <11 µg/ml against PA1 cell lines and antimicrobial activity with ZOI approximately 10-18 mm against Pseudomonas aeruginosa (P. aeruginosa), C. albicans, S. aureus and M. smegmatis (Table 6) [72][73][74][75][76][77][78][79][80][81][82][83][84][85] . Therefore, after the experimental validation of traditional use of these 15 folk medicinal species, further extensive studies are required to investigate the efficacy of these medicinal plants along with the bioactive molecules for the translational use and development of antibacterial and antifungal treatments to replace the resistant drugs.…”

Invasiveness of Alternanthera bettzickiana – Is Allelopathy a Factor?

“…HPLC analysis of whole plant aqueous extract of these weeds revealed the presence of phenolic compounds like ferrulic acid, chlorogenic acid, coumaric acid, vanillic acid and 4-hydroxy-3-methoxybenzoic acid [9]. GCMS analysis of leaf leachates of A. ficoidea confirmed the presence of phenolic compounds like tetramethyl-2-hexadecanol, tetraenoic acid, octadecatrienoic acid, methyl ester and phytol [10]. A. bettzickiana has been spreading at a very rapid rate in the uplands of Kerala, and the dominance of this species in uncropped areas raises the probability of it having allelopathic activity.…”

Phytochemical Screening of Artocarpus Hirsutus and Its Antimicrobial Potential

“…Tannins are polymeric phenols which stimulate the immune system and are considered to have wide range of anti-infective activities [7]. They make complexes with proteins, and hence they have the ability to inactivate microbial enzymes, adhesion, and transport proteins [8].…”
