Abstract
Abstract:
A review concerning the synthesis and pharmacological properties of pyrazoles obtained from Chalcone described in the literature over the last 5 years (2016-2020) was presented and discussed. Among the synthetic approaches for pyrazoles described so far, the cyclization and acetylation method of α,β-unsaturated chalcones and substituted hydrazine was selected and analyzed. 105 pyrazole derivatives (3-107) were evaluated as well as their pharmacological activities, namely, antineoplastic, anti-inflammatory, antioxidant, antibacterial, antifungal, antimycobacterial, antiplasmodial, Alzheimer's disease, enzymes inhibition (like acetylcholinesterase, carbonic anhydrase, and malonyl CoA decarboxylase), anticonvulsant, among others. Pyrazolic compounds are widely used in the new drugs design with a wide spectrum of pharmacological approaches, therefore, it is relevant to research the synthetic methods and therapeutic properties of different pyrazole derivatives.

Abstract
Background:
According to a number of previous studies, citrus fruits are rich in phytochemicals,
minerals and bioactive compounds.
Objective:
The aim of this study was to investigate the antioxidant, antimicrobial and anticoagulant
activities, phytonutrients, bioactive compounds, mineral and heavy metals in the peel and pulp of
Elachi lemon (Citrus limon).
Methods:
Phytochemical screening was performed to estimate the total polyphenol, flavonoid, tannin,
reducing sugar, total protein and vitamin C contents. High performance liquid chromatography
was performed to determine the concentrations of phenolics and ascorbic acid. Antioxidant activities
were evaluated by measuring 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity,
reducing power assay and ferric reducing antioxidant power (FRAP) assay. Antibacterial activity
was evaluated by the disc diffusion method and minimum inhibitory concentration (MIC).
Besides estimating heavy metals and minerals, activated partial thromboplastin time (aPTT) and
prothrombin time (PT) were observed for detecting anticoagulant activity.
Results:
In the case of antioxidant and antimicrobial activities, the pulp was found to be richer.
Both the peel and pulp showed similar anticoagulant activities. Among the phytonutrients, protein
content was richer in the peel than in the pulp. Catechin, rutin, tannic, gallic and vanillic acids were
detected in the peel, whereas in pulp quercetin, tannic and gallic acids were found. Pb, Cr, Cd were
present in a negligible amount whereas, Co, Cu and Fe were high in both the peel and the pulp.
Conclusion:
This study exhibits that both the peel and the pulp of Citrus limon are a rich source of
antioxidant, antimicrobial, anticoagulant, minerals and various bioactive compounds with nutritional
values.
