“…Phenolic compounds contain one or more hydroxyl group with an aromatic structure and they exist in different species of plants. The phenolic compounds have antioxidant activities because of their redox properties, which allow them to act as reducing agents, hydrogen donors and quenchers of singlet oxygen (Turan et al, 2016;Isık et al, 2015). Also, the structure of aromatic ring and the number of hydroxyl groups of phenolic compounds are important factors on antioxidant abilities.…”

Phenolic compounds of Nepeta nuda subsp. Lydiae leaves were identified by UHPLC-ESI-MS/MS. To the best of our knowledge, phenolic compounds in N. nuda subsp. Lydiae are reported for the first time. Chlorogenic acid, rosmarinic acid and quinic acid, were found to be the most abundant compound in the methanol extract of N. nuda subsp. Lydiae, among the twenty-seven compounds studied by LC-MS/MS. Also, smaller amounts of kaempferol, p-coumaric acid, tr-caffeic acid, apigenin, luteolin and rhamnetin were identified, quantitatively. In conclusion, leaves of N. nuda subsp. Lydiae have high potential of phenolic contents that mainly attributed with biological activities.

The identification and quantification of phenolic compounds of Stachys lavandulifolia Vahl. var. brachydon Boiss. by LC-MS/MS (Liquid Chromatography- tandem Mass Spectrometry) technique is the main purpose of the current study. The high concentrations of quinic acid (2534±12 ppb) and chlorogenic acid (1882±92 ppb) were detected by LC-MS/MS.. Another goal of the study is to evaluate the antioxidant activities of both ethanol and aqueous extracts of the plant material. The antioxidant potentials of extracts were determined by using five different in vitro methods including; ABTS (2,2′-Azino-bis-3-ethylbenzothiazoline-6-sulfonic acid), DPPH(1,1-diphenyl-2-picryl-hydrazyl), FRAP (Ferric ions Reducing Antioxidant Power), CUPRAC (Cupric ions Reducing Antioxidant Power), and ferric thiocyanate methods. The results revealed that the aqueous and ethanol extracts of S. lavandulifolia leaves have good antioxidant potential with high phenolic content.

“…The same results were obtained, when we used MnBr 2 ·4H 2 O or Mn(OAc) 2 ·4H 2 O as metal salts suggesting that the character of the anion was not significant for the framework formation. [23] The FTIR spectrum of the Mn(II) coordination framework was measured and compared to the spectrum of the ligand used in the synthesis (Figure 2).…”

By combining a bistriazole ligand, [1,2,3]triazolo-[4,5-f ]benzotriazole-4,8(2H,6H)-dione (H 2 C 6 N 6 O 2 ), and Mn(II) cations in water, we prepared a Mn(II) coordination framework having an unexpected structure. As revealed by single-crystal Xray analysis, the compound crystallizes in the monoclinic crystal system in the space group P2 1 /n and forms a 2D layered structure. The complex formula is [Mn 3 (C 6 N 6 O 2 ) 2 (OH) 2 (H 2 O) 4 ], and [a]
