The EtOAc, n-BuOH, and aqueous fractions from the aerial parts of Malva verticillata have been shown to promote significant recovery from alloxan-induced pancreatic islet (PI) damage in zebrafish larvae at 10 μg/mL. Therefore, this study aimed to identify the principal active components of these plant parts and their pharmacological properties. Repeated SiO2 and octadecyl SiO2 column chromatography with the aerial parts of M. verticillata led to isolation of four phenolic compounds; these compounds were identified as benzyl-α-D-galactopyranoside (1), (-)-secoisolariciresinol-9'-O-β-D-glucopyranoside (2), transferulic acid (3), and trans-ferulic acid methyl ester (4) on the basis of physicochemical and spectroscopic analyses including infrared, nuclear magnetic resonance, and fast atom bombardment-mass spectroscopy. Compounds 14 were first isolated from M. verticillata in this study. Furthermore, compounds 1–4 recovered alloxan-induced PI damage in zebrafish. Especially, compound 3 recovered the size of the injured PIs by 83.8% ( p=0.0007) compared to the alloxan-induced group, while compound 4 by 33.4% ( p=0.0072). It is the first report that trans-ferulic acid (3) exhibited the protective effect on zebrafish larvae PIs damaged by alloxan.

This study was conducted to investigate the effects of oak chips-supplementations on phenolic compound profiles of grape vinegar samples. Total acidity, volatile acids, non-volatile acids, pH, dry extract, ash, color, alcohol, total phenolic compound, individual phenolic compounds and aroma compounds of un supplemented control (UC) samples and oak chips-supplemented (OCS) samples were analyzed at the 0th, 1st and 3rd months of ageing. Total phenolic compound of UC vinegar samples was measured as 1256.50 mg GAE/L at the end of the 3rd month. Total phenolic compound of OCS vinegar samples was measured as 1521.03 mg GAE/L at the end of the 1st month and as 1470.67 mg GAE/L at the end of the 3rd month. Gallic acid, catechin and vanillic acid contents of UC vinegar samples were respectively measured as 8.43 mg/L, 22.26 mg/L and 1.78 mg/L at the end of the 3rd month. Gallic acid, catechin and vanillic acid contents of OCS vinegar samples were respectively measured as 19.12 mg/L, 17.98 mg/L and 2.58 mg/L at the end of the 3rd month. The 3-hydroxy-2-butanone, hexadecanoic acid methyl ester, 9,12-octadecadienoic acid methyl ester and 9-octadecanoic acid methyl ester quantities increased at the end of the 3rd month with oak chips-supplementation to ageing process. It was observed that oak chips-supplementation increased total phenolic compound and some individual phenolics of grape vinegar samples.

Significant Difference

The content of total polyphenols, flavonoids and coumarins in the aerial parts of pineapple weed ( Chamomilla suaveolens (Pursh) Rydb.), growing wild in Estonia, was determined chromato-spectrophotometrically, and individual polyphenols were quantified using HPLC-DAD-MS/MS. The total content of polyphenols was rather similar in flowers (9.1–11.5%) and in whole aerial parts (8.4–10.9%) of pineapple weed. The upper one-third (1/3) and upper two-thirds (2/3) of the aerial parts contained more flavonoids (0.15 – 0.20%) than the flowers (0.12%). The content of coumarins showed no significant difference between the flowers and the upper 1/3 and 2/3 of the aerial parts. The main polyphenols in the flowers were dicaffeoylquinic acids (202-380 mkg/mL), chlorogenic acids (75-185 mkg/mL), and ferulic acid glycoside (61-124 mkg/mL). Also found were quercetin galactoside, apigenin acetylglucoside, malonylapigenin glucoside, as well as luteolin, quercetin and apigenin glycosides.

The volatile constituents of the aerial parts of Centaurea formanekii Halacsy and the aerial parts, capitula and roots of C. orphanidea Heldr. & Sart. ex Boiss. ssp. thessala (Hausskn.) Dostál from Greece were extracted by hydrodistillation and analyzed. The main components in C. formanekii were hexadecanoic acid (13.6%), δ-elemene (9.1%), and spathulenol (6.9%). The main components in C. orphanidea ssp. thessala were γ-elemene (26.1%) and caryophyllene oxide (13.2%) in the aerial parts, hexadecanoic acid (33.5%) and heptacosane (6.3%) in the capitula, and hexadecanoic acid methyl ester (22.0%) and α-chamigrene (14.0%) in the roots. The chemotaxonomic significance with respect to other previously studied species of the same sections (Phalolepis and Achrolopus, respectively) is discussed.
