Classification of buckwheat honey produced in Kazakhstan according to their biochemical ingredients and bioactivities by chemometric approach.

Herein, nineteen buckwheat honey samples collected from 19 stations of different ecological zones of Kazakhstan were analysed for their pollen density, physicochemical properties, chemical composition, antioxidant, anticholinesterase, tyrosinase inhibitory, and urease inhibitory activities with chemometric approaches. Twelve phenolic compounds and fumaric acid were identified using HPLC-DAD, and mainly fumaric, p-hydroxybenzoic, p-coumaric, trans-2-hydroxy cinnamic acids, and chrysin were detected in all samples. The honey samples collected from the Northern zone exhibited best antioxidant activity in lipid peroxidation inhibitory (IC:8.

Essential Oil, Aroma, and Fatty Acid Profiles of Five Endemic Salvia Taxa from Turkey with Chemometric Analysis.

The essential oil, aroma, and fatty acid compositions of Salvia cerino-pruinosa var. cerino-pruinosa, S. cerino-pruinosa var.

Development and Validation of a Novel LC-MS/MS Method for the Quantitation of 19 Fingerprint Phytochemicals in Salvia Species: A Chemometric Approach.

Being traditionally utilized mainly as appetizers and herbal teas as well as used to ease abdominal pains, colds and gastrointestinal issues, the genus Salvia L. has gained significant consideration owing to its remarkable phytochemicals and industrial importance. The present study aimed to develop and validate an LC-MS/MS method for the qualitative and quantitative investigation of 19 fingerprint phytochemicals in six endemic Salvia species.

A Detailed Chemical and Biological Investigation of Twelve Allium Species from Eastern Anatolia with Chemometric Studies.

Allium species are widely consumed as food all over the world. The phenolic profile of ethanol extracts of aerial parts and roots of 12 Allium species, collected from five different Eastern Anatolia regions, were studied using LC-MS/MS. In vitro antioxidant, anticholinesterase, cytotoxic and antimicrobial activities were also tested.

Trace Element Analysis by ICP-MS and Chemometric Approach in Some Species: Potential to become a Biomonitor.

In this study, the branch, leaves, flowers, roots and mixed parts of different nine species were analyzed for their trace element contents by using ICP-MS. The samples were digested by concentrated nitric acid and hydrogen peroxide in a microwave by ICP-MS before the analysis. The accuracy and precision of the method was evaluated by CRM 1573a Tomato Leaves.

A Detailed Biological and Chemical Investigation of Sixteen Achillea Species' Essential Oils via Chemometric Approach.

Representatives of the Achillea genus are widely used as foods or nutraceuticals. Considering the increasing demand for herbal dietary supplements with health promoting effects, the objective of this research was to evaluate the chemical composition and biological activities of the essential oils obtained from sixteen Achillea species (A. biebersteinii, A.

Microplastic pollution at the intersection of the Aegean and Mediterranean Seas: A study of the Datça Peninsula (Turkey).

This study aims to reveal microplastic pollution. It is the first to be conducted in the South Aegean Region and one of the limited numbers of such studies in Turkey. To this aim, in September 2018 microplastic particles (MP's) pollution was evaluated on the sandy beaches along the coastline of the Datça Peninsula (Southern Aegean coast of Turkey) located at the intersection of the Aegean and Mediterranean Seas.
