Investigation of phenolic profiles and antioxidant activities of some Salvia species commonly grown in Southwest Anatolia using UPLC-ESI-MS/MS

Abstract

Aerial parts of Salvia albimaculata Hedge & Hub.-Mor., Salvia potentillifolia Boiss & Heldr. ex Bentham. and Salvia nydeggeri Hub.-Mor. from Soutwest Anatolia, Turkey were evaluated to determine their phenolic compounds and antioxidant properties. According to the ultra performance liquid chromatography with electrospray ionization tandem mass spectrometry (UPLC-ESO-MS/MS) analysis results, caffeic acid (3582.8 ± 2.5 μg/g, 2956.5 ± 4.6 μg/g and 2457.7 ± 3.1 μg/g) and 3,4-dihydroxy benzoic acid (1846.2 ± 3.1 μg/g, 2019.1 ± 2.2 μg/g and 1901.3 ± 1.5 μg/g) were found to be in the highest concentrations in S. potentillifolia, S. albimaculata and S. nydeggeri, respectively. Total amounts of phenolics and flavonoids were determined highest in ethyl acetate extracts of samples and varied from 62.4 ± 0.1 to 55.4 ± 0.0 µg PEs/mg and from 296.8 ± 1.4 to 198.4 ± 1.5 µg QEs/mg, respectively. Antioxidant activity of S. potentillifolia was found to be higher than the others for ABTS •+ and β-carotene linoleic acid assays (SC 50 = 49.8 ± 0.9 and OC 50 = 26.1 ± 0.6 µg /mL, respectively) while S. albimaculata was found to be higher for DPPH • assay (SC 50 = 227.4 ± 1.1 µg/mL).

Antioxidant Properties of Lyophilized Rosemary and Sage Extracts and its Effect to Prevent Lipid Oxidation in Poultry Pátê

“…However, in this study, the sage extract showed superiority in the content of flavonoids (15.03 mg QE/g of plant) compared with the lyophilized rosemary extract (11.89 mg QE/g). Our results showed that the total phenolic content of lyophilized sage extract was lower than the values reported by Kivrak et al [11], who found, for total phenolic compounds, 52.3 mg of pyrocatechol/g in the methanolic extract of sage from Turkey. These differences between the TPC and TFC quantities obtained in our study and found in the literature can be attributed to the different methods of extraction, solvents and temperatures employed.…”

Biochemical parameters and antioxidant property of three Salvia L. taxa endemic in Turkey

“…The myricetin, morin, quercetin, kaempferol, and naringin amounts of the studied taxa were either absent or in low amounts in the present study (Table 2). In a study conducted by Kivrak et al (2019), it was reported that Salvia had kaempferol, naringenin, rutin, vanillic acid, caffeic acid, and ferulic acid content. However, they found that Salvia did not have myricetin, resveratrol and quercetin (Kivrak et al, 2019).…”
