Abstract
The conventional one-drug-one-disease theory has lost its sheen in multigenic diseases such as Alzheimer's disease (AD). Propolis, a honeybee-derived product has ethnopharmacological evidence of antioxidant, anti-inflammatory, antimicrobial and neuroprotective properties. However, the chemical composition is complex and highly variable geographically. So, to leverage the potential of propolis as an effective treatment modality, it is essential to understand the role of each phytochemical in the AD pathophysiology. Therefore, the present study was aimed at investigating the anti-Alzheimer effect of bioactive in Indian propolis (IP) by combining LC-MS/MS fingerprinting, with network-based analysis and experimental validation. First, phytoconstituents in IP extract were identified using an in-house LC-MS/MS method. The drug likeness and toxicity were assessed, followed by identification of AD targets. The constituent-target-gene network was then constructed along with protein-protein interactions, gene pathway, ontology, and enrichment analysis. LC-MS/MS analysis identified 16 known metabolites with druggable properties except for luteolin-5-methyl ether. The network pharmacology-based analysis revealed that the hit propolis constituents were majorly flavonoids, whereas the main AD-associated targets were MAOB, ESR1, BACE1, AChE, CDK5, GSK3β, and PTGS2. A total of 18 gene pathways were identified to be associated, with the pathways related to AD among the topmost enriched. Molecular docking analysis against top AD targets resulted in suitable binding interactions at the active site of target proteins. Further, the protective role of IP in AD was confirmed with cell-line studies on PC-12, in situ AChE inhibition, and antioxidant assays.

Abstract
INTRODUCTION During the processing of fresh plants, prolonged exposure to the air can cause rapid oxidative changes, and this is further accelerated if they have large surface areas. These changes can ultimately lead to losses in valuable ingredients and deterioration of the final product. Consequently, in the food, cosmetics, and pharmaceutical industries, oxidation and the use of antioxidant conservatives are major considerations during processing and production. However, similar considerations are not currently made for herbal medicines. The differences in the UV-Vis spectra of several commercial herbal mother tinctures were investigated here to determine if the oxidation process occurred and should thus be considered during their production. METHODS The impact of air exposure on comminuted fresh Melissa officinalis and on the quality of the resulting mother tincture was evaluated using UV-Vis spectrophotometric analysis, antioxidant tests (potassium permanganate and FOLIN-Ciocalteu), and high-performance thin-layer chromatography. RESULTS A time-dependent decrease in phenolic compounds, UV absorbance, and antioxidant capacity of the Melissa officinalis mother tincture were observed. Specifically, the antioxidant capacity of ground Melissa officinalis in the resulting herbal mother tincture was reduced by 40.47% and 55.52% after 5 and 30 min of air exposure, respectively. CONCLUSIONS The results indicate that the Melissa officinalis mother tincture is affected if its comminuted starting material is exposed to air during the manufacturing process and that this should be considered when producing fresh herbal medicine plant products in the future.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ashwagandha is a reputed herb in traditional Ayurveda, used for various ailments and improving general well-being. Improved cardiorespiratory endurance can aid in attaining better physiological, metabolic, and functional abilities in humans. According to Ayurveda, Ashwagandha has such potential to improve human health. AIM OF THE STUDY This study aimed to evaluate the efficacy and safety of Ashwagandha root extract in enhancing cardiorespiratory endurance in healthy athletic adults. MATERIALS AND METHODS Fifty healthy athletic adults were selected randomly and equally allocated to Ashwagandha and placebo groups. The Ashwagandha group received 300 mg of Ashwagandha root extract capsules, twice daily, for 8-weeks. Cardiorespiratory endurance was assessed by measuring the maximum aerobic capacity (VO2 max). Estimation of stress management was done through Total Quality Recovery Scores (TQR), Recovery-Stress Questionnaire for Athletes (RESTQ), and Daily Analysis of Life Demands for Athletes (DALDA) questionnaires along with the antioxidant level measurement. RESULTS At the end of the study, a statistically significant improvement in VO2 max outcome was observed in the Ashwagandha group when compared to the placebo group (P = 0.0074). The subjects in the Ashwagandha group also displayed a statistically significant increase at the end of the study when compared to the baseline (P < 0.0001). Significantly improved TQR scores were observed in the Ashwagandha group members compared to their placebo counterparts (P < 0.0001). DALDA questionnaire analysis in the Ashwagandha group was found statistically significant (P < 0.0001) compared to the placebo group. RESTQ assessment also yielded better outcomes, especially for fatigue recovery (P < 0.0001), lack of energy (P < 0.0001), and fitness analysis (P < 0.0001). The enhanced antioxidant level was significant (P < 0.0001) in the Ashwagandha group. CONCLUSION The present findings suggest that Ashwagandha root extract can successfully enhance cardiorespiratory endurance and improve the quality of life in healthy athletic adults. No adverse events were reported by any of the subjects in this study.

Abstract
Epilepsy has been associated with several behavioral changes such as depression and anxiety while some antiepileptic drugs can precipitate psychiatric conditions in patients. This study evaluated the ameliorative effect of creatine on seizure severity and behavioral changes in pentylenetetrazole (PTZ) kindled mice. Mice were kindled by administering sub-convulsive doses of PTZ (35 mg/kg i.p.) at interval of 48 h. The naïve group (n = 7) constituted group 1, while successfully kindled mice were randomly assigned to five groups (n = 7). Group II served as vehicle treated group; groups III-V were treated with creatine 75, 150, and 300 mg/kg/day, p.o; Group V was given 25 mg/kg/day of phenytoin p.o. The treatment was for 15 consecutive days. The intensity of convulsion was scored according to a seven-point scale ranging from stage 0-7. Tail suspension test (TST) and Elevated plus maze (EPM) were utilized to assess depression and anxiety-like behavior respectively. After behavioral evaluation on day 15th, their brain was isolated and assayed for catalase, superoxide dismutase, reduced glutathione, and malondialdehyde. There was a significant (p < 0.05) reduction in the seizure scores, anxiety and depression-like behaviors in mice from the 5th day of treatment. The antioxidant assays revealed significant (p < 0.05) increase in catalase and reduced glutathione, and significant (p < 0.05) reduction in lipid peroxidation in treated mice. This study provides evidence for the seizure reducing property of creatine and its ameliorating potential on anxiety and depressive-like behaviors that follows seizure episodes.

Abstract
With the rapid development of nanotechnology, much has been anticipated with silver nanoparticles (AgNPs) due to their extensive industrial and commercial applications. However, it has raised concerns over environmental safety and human health effects. In this study, AgNPs were bio-fabricated using aqueous extract of Microchaete and their medical applications like antioxidant, anti-proliferative, and apoptosis were done. The biosynthesis of AgNPs was continuously followed by UV-vis spectrophotometric analysis. The physiochemical properties like shape, size, crystallinity, and polydispersity of the nanoparticles were determined by Scanning Electron Microscopy (SEM) along with EDX, Transmission Electron Microscope (TEM), Atomic Force Microscope (AFM), dynamic light scattering (DLS), and X-Ray Diffraction (XRD). Biosynthesized 7.0 nm sized AgNPs with the crystalline structure (crystalline size 4.8 nm) having a hydrodynamic diameter of 38.74 ± 2.6 nm was achieved due to the involvement of reducing agents present in the cyanobacterial extract. The IC50 values of the AgNPs were evaluated as 75 µg/ml and 79.41 µg/ml with HepG2 and MCF-7 cell lines. Different in-vitro cellular assays investigated in the present study exhibited antioxidant, anti-proliferative, and apoptotic activities. Probably delayed apoptosis in HepG2 and MCF-7 is due to better antioxidant activities of Microchaete based AgNPs.

Abstract
A new series of pyrrole analogs were developed via the microwave irradiation synthesis. Consequently, got a high yield of the products. As pyrroles are familiar for showing various biological properties, all obtained compounds were screened for their antioxidant properties, most of the compounds showing significant activity. In fact, the motifs 5e, 5g, 5h and 5m showed outstanding antioxidant properties. Further, to enlighten the biologically energetic behavior underlying the antioxidant activity, compounds DFT studies were performed. Noteworthy results have been attained and the structure activity relationship (SAR) was discussed with the support of this results. It was found that highly biological active compounds exhibited a low HOMO-LUMO energy gap (Eg) and the high Eg value compounds show very low/negligible or inactive antioxidant activities. In other cases, compounds containing high HOMO energy levels also provide high antioxidant activity. The thought-provoking point of our results is that theoretical descriptors of the HOMO-LUMO energy gap and the highest occupied molecular orbital energy are important descriptors in the bioorganic research to support the biological experiments.

Abstract
The magnetically isolable nanobiocomposites have significant impact as the modified new generation catalysts in recent days. This has persuaded us to design and synthesis of a novel Ag NPs decorated biguanidine-chitosan (Bigua-CS) dual biomolecular functionalized core-shell type magnetic nanocomposite (Ag/Bigua-CS@Fe3O4). Bigua-CS could be introducing polysaccharide materials as potential coating agent to immobilizing and stabilizing metal nanoparticles. The material was characterized using several advanced techniques like fourier transformed infrared spectroscopy (FT-IR), inductively coupled plasma (ICP), field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDX), atomic mapping, high resolution transmission electron microscopy (HR-TEM), vibrating sample magnetometer (VSM) and X-ray diffraction (XRD). Towards the chemical applications of the material, we headed the multicomponent synthesis of diverse propargylamines by A3 coupling in water, which ended up with excellent yields. Due to strong paramagnetism, the catalyst was easily isolable and reused in 9cycles without any leaching and considerable change in reactivity. In addition, the catalyst was engaged in biological assays like study of anti-oxidant properties by DPPH mediated free radical scavenging test using BHT as a reference molecule. Thereafter, on having a significant IC50 value in radical scavenging assay, we extended the bio-application of the catalyst in anticancer study of adenocarcinoma cells of human lungs. The three different cancer cell lines, PC-14, LC-2/ad and HLC-1 were used in this regard. The best result was achieved in the case of PC-14 cell line with strong IC50 values.

Abstract
The leaves of Ocimum sanctum were extracted in methanol (OsM) and sequentially fractionated with n-hexane (OsH), ethylacetate (OsE) and butanol (OsB) to find the best extraction solvent for antioxidants from the herb known for its medicinal values. OsB was rich in both total polyphenolic content (TPC) (212.26 ± 6.3 mg GAE/g extract) and total flavonoid contents (TFC) (54.51 ± 3.5 mg QE/g extract). OsE also had significantly high TPC (202.71 ± 5.5 mg GAE/g extract). The EC50 based on DPPH (3.91 ± 0.3 μg/ml), ABTS (1.6 ± 0.1 μg/ml) and phosphomolybdate (2.31 ± 0.1 μg/ml) for OsB; hydroxyl (5.3 ± 0.4 μg/ml), superoxide (7.32 ± 0.9 μg/ml) radicals for OsM and DPPH (8.61 ± 0.6 μg/ml), phosphomolybdate (2.43 ± 0.1 μg/ml) and ABTS (5.3 ± 0.4 μg/ml) for OsE were lower than ascorbic acid showing potential antioxidant properties. EC50 values of different fractions for DPPH anion, ABTS cation free radical scavenging and phosphomolybdate reducing property were significantly and positively correlated with TPC and TFC. LC-MS analysis of OsB and OsE showed the presence of luteolin, apigenin, rosmarinic, chlorogenic, caffeic acid and their derivatives. Quercetin is extracted in ethylacetate fraction. Overall data revealed that O. sanctum leaf extracts in butanol and ethylacetate with high polyphenolics and flavonoids, had strong antioxidant potential.

Abstract
The nematode Caenorhabditis elegans is a versatile and powerful model organism for animal experimental research and, despite being an invertebrate, displays remarkably similar molecular bases and conserved cellular pathways to those of humans. Oxidative stress is an etiological factor that influences numerous diseases, degenerative processes and aging. C. elegans has revealed as an opportune and feasible organism to investigate the antioxidant effects of different bioactives or complex food matrices, and a number of protocols have been developed by using different oxidative stressors. Carotenoids are recognized as quenchers and scavengers of reactive oxygen species, and many of their related health benefits attributed in the diet are tightly linked to their antioxidant properties. In this chapter, we report a simple and rapid assay to evaluate the protection capacity of pure carotenoids or complex carotenoid extracts against oxidative stress in the model system C. elegans. The protocol describes a representative feeding experiment by adding carotenoids to the nematode growth medium and after an incubation period, the C. elegans populations fed with carotenoids are exposed to an acute oxidative stress by using H2O2 as oxidative agent. The protection against oxidative stress is evaluated as the survival rate of the nematodes fed with the carotenoid prior to receiving oxidative treatment compared with the survival rate of control nematode population. In order to confirm the carotenoid intake by the nematodes during the feeding experiment a bioassimilation experiment is also reported.

Abstract
The goal of this research was to explore the preliminary anticancer properties of five plants namely Calotropis procera, Moringa oleifera, Millettia pinnata, Basela alba and Euphorbia neriifolia available in Jharkhand which is used for the medicinal purpose by local tribes. In the present study, plant leaves from five species were collected, dried and extracted with solvents of increasing polarity, followed by assessment of their cytotoxicity in A549 non-small-cell lung cancer cells. In the antimicrobial assay, the methanol extract of the M. pinnata leaves exhibited comparatively higher zone of inhibition of 0.7 ± 0.20 cm against a Salmonella typhi culture than the other extracts. M. pinnata leaves extract also displayed the maximum percentage inhibition in the DPPH, 83.97 ± 0.01 FRAP, 193.14 ± 3.01 mM assays. Furthermore, the cytotoxicity of the chloroform (37.45 ± 1.04) and ethyl acetate extracts (34.20 ± 0.81) of M. pinnata against A549 cells was found relatively higher with respect to another extract. In contrast, a study with the L132 normal epithelial lung cell line revealed less toxicity from the chloroform extract (0.33 ± 0.19) compared to the ethyl acetate extract (6.65 ± 0.59). Based on these findings, phytochemical investigation on chloroform and ethyl acetate extract of M. pinnata was performed using UPLC-ESI-MS/MS analysis revealing the presence of β-sitosterol, lanceolatin B, karanjin, and stigmasterol. Congruently, a complete phytochemical and cytotoxic investigation of the M. pinnata extract constituents might infer the potency of this extract/s as anticancer, antioxidant and antimicrobial agents.

Abstract
The gold nanoparticles (AuNPs) were synthesized using the lichen Parmelia sulcata extract (PSE) and characterized. The peaks of ultraviolet spectrophotometer and Fourier transmission infrared confirmed the formation of nanoparticles and the bioactive compounds of the lichen being responsible for reducing and capping of the particles. The face-centered cubic particles were determined by XRD peaks at 111, 200, 220, and 311. The elemental composition and spherical shape of AuNPs were confirmed by energy-dispersive spectroscopy and transmission electron microscopy. The average particle size is 54 nm, and the zeta potential - 18 was ascertained by dynamic light scattering. The potential effect of synthesized nanoparticles and lichen extracts was evaluated for antioxidant bioassays like DPPH and H2O2 and tested for mosquitocidal activity against Anopheles stephensi. Results showed that the lichen extract and AuNPs have the capability to scavenge the free radicals with the IC50 values of DPPH being 1020 and 815 μg/ml and the IC50 values of H2O2 being 694 and 510 μg/ml, respectively. The mosquitocidal experimental results in this study showed the inhibition of A. stephensi and A. aegypti against the larvae (I-IV instar), pupae, adult, and egg hatching. On comparison, A. stephensi showed effective inhibition than A. aegypti even at low concentration. Based on the obtained results, gold nanoparticles synthesized using PSE showed an excellent mosquitocidal effect against Anopheles stephensi.

Abstract
Natural foods are used in many folks and household treatments and have immense potential to treat a serious complication and health benefits, in addition to the basic nutritional values. These food products improve health, delay the aging process, increase life expectancy, and possibly prevent chronic diseases. Purple head Brassica oleracea L. var. italica Plenck is one of such foods and in current studies was explored for chemical compounds at different development stages by gas chromatography-mass spectrometry. Antioxidant potential was explored employing different assays like molybdate ion reduction, DPPH, superoxide anion radical scavenging and plasmid nicking assay. Inspired by antioxidant activity results, we further explored these extracts for antiproliferative potential by morphological changes, cell cycle analysis, measurement of intracellular peroxides and mitochondrial membrane potential changes. Current study provides the scientific basis for the use of broccoli as easily affordable potent functional food.

Abstract
Assays assessing non-enzymatic hydrogen peroxide antioxidant capacities are often hampered by the high UV absorption of the sample itself. This is a typical problem in studies using plant extracts with high polyphenol content. Our assay is based on comparing the 405 nm absorption of the product of potassium iodine and hydrogen peroxide in the presence and absence of a putative hydrogen peroxide reactive antioxidant. This method is free of interference with either hydrogen peroxide or antioxidant self-absorption and it is also suitable for high-throughput plate reader applications.

Abstract
The current study summarizes a unique green process for the synthesis of gold nanoparticles by simple treatment of gold salts with aqueous extract of Nepenthes khasiana (NK)--a red listed medicinal plant and its characterization. Study on the effect of different process parameters like temperature, pH and stirring on surface and stability characteristics has been demonstrated. Formation of GNPs was visually observed by change in color from colorless to wine red and characterized by UV-Visible spectroscopy, FT-IR spectroscopy, Zetasizer, X-RD, ICP-AES, SEM-EDAX, AFM and TEM. In vitro stability studies of gold colloidal dispersion in various blood components suggest that, NK mediated GNPs exhibit remarkable in vitro stability in 2% bovine serum albumin, 2% human serum albumin (HSA), 0.2M histidine, and 0.2M cysteine but unstable in 5% NaCl solution and acidic pH. Biocompatibility of NK stabilized GNPs against normal mouse fibroblasts (L929) cell lines revealed nontoxic nature of GNPs and thus provides exceptional opportunities for their uses as nanomedicine for diagnosis and drug therapy. The role of antioxidant phytochemicals (flavonoids and polyphenols) of NK extract in synthesis of biocompatible and stabilized GNPs was demonstrated by estimating total flavonoid content, total phenolic content and total antioxidant capacity of extract before and after formation of GNPs. Fast and easy synthesis of biocompatible GNPs possesses unique physical and chemical features which serve as an advantage for its use in various biomedical applications. The overall approach designated in the present research investigation for the synthesis of GNPs is based on all 12 principles of green chemistry, in which no man-made chemical other than the gold chloride was used.

Abstract
The present work involves extraction of phytochemicals from the root bark of a well-known Indian traditional medicinal plant, viz. Mammea suriga, with various solvents and evaluation of their in vitro antimicrobial and antioxidant activities using standard methods. The phytochemical analysis indicates the presence of some interesting secondary metabolites like flavonoids, cardiac glycosides, alkaloids, saponins and tannins in the extracts. Also, the solvent extracts displayed promising antimicrobial activity against Staphylococcus aureus, Bacillus subtilis and Cryptococcus neoformans with inhibition zone in a range of 20-33 mm. Further, results of their antioxidant screening revealed that aqueous extract (with IC50 values of 111.51±1.03 and 31.05±0.92 μg/mL in total reducing power assay and DPHH radical scavenging assay, respectively) and ethanolic extract (with IC50 values of 128.00±1.01 and 33.25±0.89 μg/mL in total reducing power assay and DPHH radical scavenging assay, respectively) were better antioxidants than standard ascorbic acid. Interestingly, FT-IR analysis of each extract established the presence of various biologically active functional groups in it.

Abstract
The objective of this study is to analyze the chemical composition and volatiles present in two medicinal rice varieties of "karungkuravai" and "mappilai samba" and to investigate their total phenolic content and bio activity. Chemical composition of the rice varieties was analyzed using gas chromatography/mass spectroscopy (GC-MS), the volatile compounds are identified using static head space analysis (SHS) followed by GC-MS. Total phenolic content (TPC) is estimated using Folin Ciocalteu colorimetric method, antioxidant assay is done using 1, 1-diphenyl-2-picrylhydrazyl (DPPH) assay and ferric reducing antioxidant power (FRAP) assay. GC-MS and SHS analysis identified pharmaceutically important phytochemicals present in the rice variety. The compounds like "curlone" and "7-chloro-1,3-dihydro-5-phenyl-1-(trimethylsilyl)- 2H-1-4-benzodiazapene-2-one" are identified for the first time in any rice variety. Phenols are found to be present in both rice varieties. Both rice varieties also showed antioxidant activity in both DPPH and FRAP assays and the IC50 values were 91.08 μg/ml and 359.93 μg/ml for "karungkuravai" and "mappilai samba", respectively. . The correlation coefficient and regression analysis of total phenolic content with DPPH assay and FRAP assay show significant positive correlation coefficient values and coefficient of regression values.

Abstract
Here, we report an improved method to analyze antioxidant activity using the europium tetracycline assay developed by Duerkop and Wolfbeis (J Fluor 15(5):755-761, 2005). The europium tetracycline hydrogen peroxide reduction assay (EHRA) accurately measures antioxidant activity based on hydrogen peroxide scavenging. Several known antioxidant compounds were assessed with the EHRA and a stoichiometric relationship between the number of oxidant molecules trapped per molecule of antioxidant was identified. Various extracts of hops were also tested to validate this method for use with natural extracts; water extraction yielded the highest level of antioxidant activity. Hop leaves were shown to be a better source of antioxidants relative to the traditional hop cones. The data also indicate that the EHRA may serve to breach the hydrophilic/lipophilic gap in antioxidant screening as the europium tetracycline probe is effective in many solvents. The EHRA thus provides a robust and inexpensive measure of antioxidant activity.
