Description
SORUMLU ÜRETİM VE TÜKETİM Sürdürülebilir üretim ve tüketim kalıplarını sağlamak: Ekonomik büyüme ve sürdürülebilir kalkınmayı başarmak için, malları ve kaynakları üretme ve tüketme biçimlerimizi değiştirmek suretiyle ekolojik ayak izimizi derhal azaltmamız gerekiyor. Dünya genelinde en büyük su tüketicisi tarımdır ve tarımsal sulama, insanların kullandığı tüm taze suyun yaklaşık %70’ini buluyor.

    This study was the first phytochemical and biological activity report on Alcea pallida and Alcea apterocarpa extracts. The main constituents of the essential oils were identified as arachidic acid (34.2%) for A. pallida, and hexatriacontane (25.3%) for A. apterocarpa. The main constituents of the fatty acids obtained from petroleum ether extracts of A. pallida and A. apterocarpa were identified as palmitic acid (31.2%) and oleic acid (25.6%), respectively. The phenolic compositions of the samples were determined using HPLC (LC-20 liquid chromatographic system). A. pallida and A. apterocarpa showed the same peaks which were ascorbic, caffeic, salicylic and p-hydroxybenzoic acids and quercetin, respectively. Salicylic acid showed the highest abundance. Among the eight extracts, the acetone extract of A. pallida possessed the best ABTS cation radical scavenging activity and moderate butyryl-cholinesterase activity at 200 mu g/mL. The A. pallida acetone extract exhibited 53.12% inhibition in DPPH free radical scavenging activity method at 100 mu g/mL concentration. The acetone extract of A. pallida showed weak antimicrobial activity against Escherichia coli, Streptococcus pyogenes, Staphylococcus aureus, Pseudomonas aeruginosa and moderate activity against Candida albicans (inhibition zone diameter 16 mm). The acetone extract of A. apterocarpa showed moderate activity against C. albicans (inhibition zone diameter 14 mm) and S. aureus (inhibition zone diameter 13 mm); weak activity against E. coli., S0 pyogenes, and P. aeruginosa.

    The purpose of the present work was to determine the phenolic and the fatty acids profiles by LC-MS/MS and GC/MS with their antioxidant, anticholinesterase and antimicrobial activities, and aflatoxin contents of Malva neglecta and Malvella sherardiana. The phenolic contents of M. neglecta and M. sherardiana were determined by LC-MS/MS. Malic and 4-OH benzoic acids were found to be the most abundant compounds in M. neglecta and M. sherardiana, respectively. On the other hand, essential oil and fatty acid compositions were determined by GC/MS analysis. The methanol extracts of the plants showed the highest effect in all antioxidant assays in this study. The methanol extract of M. neglecta showed the highest activity among the petroleum ether, acetone, methanol and water extracts against acetyl-and butyryl-cholinesterase enzymes (53.68% and 63.95% inhibition ratio, respectively). The acetone extracts of M. neglacta and M. sherardiana exhibited moderate activity against C. albicans with 18 and 17 mm inhibion zone diameter, respectively. The results of the present study is also showed that the M. neglecta and M. sherardiana can also be used as a food source due to its high phenolic acid content and good antioxidant property. Also, the samples were aflatoxin free.
