A total number of 5206 samples from twenty one different vegetables and fruits were collected during 2009-2017. Pesticides in concentrations exceeding the maximum residue levels were found in 1194 analysed samples (22.9% of total). Thirteen insecticides, four fungicides, two acaricides and one herbicide were detected in the analysed samples. The estimated daily intake (EDI) has been established between 0.000001 and 0.0002 mg/kg of body weight/day. Calculated values of EDIs are lower than the levels of acceptable daily intake. The calculated hazard indices ranged from 0.000004 up to 0.15 for the analysed pesticides and the highest value of hazard index was calculated for diazinon, being of 0.15. It might be concluded that the long-term consumption of vegetables and fruits could pose a health risk for the population of the Republic of Moldova, since the minimum norms used for risk estimation do not reflect real food consumption pattern in the Republic of Moldova.","PeriodicalId":9922,"journal":{"name":"Chemistry Journal of Moldova","volume":"23 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2019-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85199182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, five different solvents namely: water, acetone, ethanol, methanol and hexane, and three extraction techniques were used to extract phenolic compounds: microwave-assisted extraction, Soxhlet and maceration. Total phenolics (TPC), total flavonoids (TFC) and condensed tannins contents (CTC) were determined. The results showed that different solvents with different polarity had a major effect on polyphenolic contents and antioxidant activity; the highest TPC (122.15-144.82 mg GAE/g), TFC (64.12-70.32 mg QE/g) and CTC (30.38-36.09 mg CE/g) were obtained with methanol. However, different extraction methods gave comparable results. In vitro antioxidant activities were evaluated using the DPPH radical scavenging ability, reducing capacity and β-carotene bleaching assay. The methanolic extract showed the highest scavenging abilities on DPPH radicals and lipid peroxidation, while the aqueous extract exhibited the strongest reducing power. Microwave-assisted extraction was the best suited for the extraction of antioxidant molecules when compared to Soxhlet and maceration.","PeriodicalId":9922,"journal":{"name":"Chemistry Journal of Moldova","volume":"13 1","pages":"79-89"},"PeriodicalIF":0.5,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73036813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structure-activity relationship was investigated to obtain a better understanding of the relationship between the chemical structure of the synthesized compounds and their corresponding biological activity. Compounds 2b and 3b exhibited potent antibacterial activities against Bacillus subtilis bacteria comparable to that of Ampicillin standard. Structure-activity relationship studies revealed that the presence of withdrawing carbonyl group on 5-position of pyrazole moiety 2b, phenylpyrazole moiety 3b led to an enhancement in the antibacterial activity of pyrazole derivatives. Furthermore, the presence of carbonyl group on 2-position of the pyrimidine ring of compounds 4a, 5a and 6a has a significant effect on their antibacterial activity against Bacillus subtilis. The antifungal studies indicated that compounds 3b, 4b, 7 and 9 have comparable antifungal activity to that of standard Amphotericin B against Candida albicans and Aspergillus flavus fungi.","PeriodicalId":9922,"journal":{"name":"Chemistry Journal of Moldova","volume":"17 1","pages":"105-116"},"PeriodicalIF":0.5,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81815664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
