The formulation and evaluation of toothpaste contain Aloe vera along with the combination of sodium chloride. Aloe vera shows a number of uses either internally or externally, and the number of uses also increases as the research going on. In this formulation, we tried to find out the antimicrobial activity of Aloe vera in toothpaste formulation, for the said purpose we use S. aureus culture. After designing the batches in software Design Expert® 10, the batches were formulated and evaluated. At the end of work, we found that the prepared toothpaste shows considerable zone of inhibition which concludes its antimicrobial activity. The formulation also shows sufficient foaming power for its cleansing action. The observed results were found to significant concerning the chosen cubic model in software Design Expert® 10. Thus from the collected results, we concluded that the toothpaste containing a combination of Aloe and sodium chloride possesses antimicrobial activity, but for its practical use its necessary to determine its effect on oral cavities and probable side effects after...

The active ingredient flavonoids especially Flavones, e.g., Quercetin was identified from the methanol extract of Alpinia officinarum. This study evaluates the antidepressant activity of Alpinia officinarum (L.) wild Hance (Zingiberaceae) in Swiss Albino mice models. The antidepressant activity was evaluated by using different animal models viz. tail suspension test, despair swim test, potentiation of norepinephrine toxicity test, 5-hydroxytryptophan potentiation in Swiss Albino mice. The methanol extract of Alpinia officinarum significantly increases Na+, K+-ATPase level in the brain in the tail suspension test model. An antidepressant effect in the despair swim test was confirmed by the increase in monoamines (NE, DA, 5HT) and γ-aminobutyric acid levels in the brain. Alpinia officinarum methanol extract also contributes to the normal regulation of the HPA axis by significant (P<0.001) decreased in plasma corticosterone level. Alpinia officinarum (400 mg/kg) showed antidepressant potential by increasing the number of head twitches induced by 5 HTP. Antidepressant effect of an extract of Alpinia officinarum at a dose of 400 mg/kg could be via modulation of brain monoamines...

Portulaca oleracea and Portulaca quadrifida have been used traditionally have been used for their pharmacological properties and consumed as a part of the diet. Anti-oxidative property of phytochemicals might play a role in their observed benefits, and phenolic compounds are known to be the major contributors towards the anti-oxidant property of phytochemicals. The objective of this study was to quantify the total phenolic content of extracts obtained by microwave extraction of these plant species using a validated technique. The plant species were collected and authenticated. Microwave-assisted extraction of separate plant parts using different solvents was carried out. The total phenolic content was measured using a modified Folin-Ciocalteau method, and the method was validated for linearity, range, limit of detection, limit of quantification, recovery, and precision. Amongst the tested extracts, the ethanolic extract of P. oleraceae seed contained the highest amount of total phenolic compounds. The stated method for quantifying total phenolic compounds was found to be precise and reliable, and the further study of the anti-oxidant property of these...

Sida acuta is one of the medically active plants used for the treatment of multifaceted diseases. However, an elaborated investigation on the phytochemical composition of the ethanolic extract of the leaves of this plant is yet to be deciphered. So, in this quantification of phytochemicals, in-vitro free radical scavenging activity, enzymatic and non-enzymatic antioxidant levels in the fresh leaves, HPTLC fingerprinting and GC-MS analysis in the ethanolic extract of Sida acuta leaves were done. In-vitro antioxidant activities were assayed using DPPH, ABTS, nitric oxide, hydroxyl radical and ferric ions, while ascorbic acid is used as the standard. The results indicated the presence of flavonoids, tannins, phenols, and alkaloids in a reasonably good amount which has substantiated the results of HPTLC. All the tested antioxidants were present prominently in the leaves, specifically catalase and glutathione peroxidase, which may be responsible for the prominent radical scavenging tendency of the extract against the tested free radicals. The GC-MS analysis observed the presence of 35 different compounds each belonging to different classes such...

This study reports the potential of Alternanthera sessilis leaves as antioxidant, antimicrobial, anti-inflammatory and anti-diabetic agent and also the characterization of a novel phytochemical from A. sessilis using bio-activity guided extraction. Antimicrobial property was studied against five bacterial pathogens, Escherichia coli (MTCC: 1687), Bacillus cereus (MTCC: 0430), Klebsiella pneumonia (MTCC: 7028), Staphylococcus aureus (MTCC: 3160), Proteus mirabilis (MTCC: 3310) and against two fungal pathogens, Aspergillus niger [MTCC 281] and Aspergillus flavus [MTCC 10938]. Petroleum ether extract of A. sessilis leaves demonstrated significant antimicrobial property and hence was further purified to identify its active phytochemicals. Silica-gel Column Chromatography followed by antimicrobial screening, lead to the identification of the active fraction, that was characterized by spectroscopic analyses. FT-IR, GC-MS and NMR (C13, and DEPT-45; 90; 135) analysis of the active fraction, characterized the phytochemical to be 3,3’-(propane-2, 2-diyl)-bis-(3,4,5,6,7,8-hexahydro-1H-isochromene) abbreviated as PDHC. To the best of knowledge, this is the first report of PDHC due to novelty in its chemical structure. In-silico molecular docking was performed for this identified compound to identify...
