Phytochemicals, antimicrobial, and sporicidal activities of moss, Dicranum polysetum Sw., against certain honey bee bacterial pathogens.

Beekeeping is an important agricultural and commercial activity globally practiced. Honey bee is attacked by certain infectious pathogens. Most important brood diseases are bacterial including American Foulbrood (AFB), caused by Paenibacillus larvae (P.

Biological Activity and Phytochemical Analysis of Dicranum scoparium against the Bacterial Disease for Honey Bee.

Bacterial diseases, such as American Foulbrood (AFB) and European Foulbrood (EFB), are known to have catastrophic effects on honey bees (if left to spread, can wipe out entire colonies), leading to severe financial losses in the beekeeping industry. The aim of this study was to evaluate the pharmacological properties of methanol extract and its fractions (ethyl acetate, hexane, water) derived from Dicranum scoparium Hedw., which could be utilized as a potential drug to prevent the bacterial diseases (AFB and EFB) affecting the honey bees.

Antimicrobial and lipase inhibition of essential oil and solvent extracts of var. and characterization of the essential oil.

The essential oil (EO) of var. was analyzed using GC-FID / MS. A total of 51 compounds were determined from this taxon, accounting for 99.

Chemical Variation, Antimicrobial, Nitric Oxide Scavenging Activities and Tyrosinase Inhibition of Essential Oils and Solvent Extracts from Moench Growing in Turkey.

Volatile organic compositions of the essential oils (EOs), solid-phase microextraction (SPME) and SPME of -hexane extracts from the flower and stem-leaf of were analyzed by GC-FID/MS. A total of 107 constituents were characterized, flower and stem-leaf parts of the plant were found to contain different volatile organic compounds. Tricosane (29.

Two new dihydroisocoumarins and terpenoids from Sümbül an endemic species to Turkey and their antimicrobial activity.

Two new dihydroisocoumarins (scorzolongin I (), and scorzolongin II ()) and nine known compounds (3',5'-dimethoxy hydrangenol (scorzolongin III, ), cladantholide (), dammar-24-ene-3-ol (), taraxasterol (), -sitosterol (), mangifgerursanone (), and a mixture of α-amyrenone (), β-amyrenone (), and dammar-24-ene-3-one () in about 1:1:2 ratio) were identified from the dichloromethane fraction of . The structure of all compounds ( were elucidated by extensive 1D and 2D NMR (H, C/APT, COSY, HMBC, HSQC, and NOESY) spectroscopy, UV, FT-IR, and LC-QTOF-MS data and by comparison of their NMR data with the literature. These compounds have been isolated from for the first time.

New chlorogenic acid derivatives and triterpenoids from Scorzonera aucheriana.

Chromatographic separation of-hexane and ethyl acetate fraction of a crude methanol extract obtained from aerial parts of theDC collected from Sivas province of Turkey yielded nine natural compounds; two new 3-caffeoyl-quinic acid analogs (-), one new taraxasterol oleate (), and six known triterpenoids taraxasterol (), taraxasterol acetate (), ptiloepoxide (), lupeol (), lupeol acetate (), and-sitosterol () were characterized. The structures of the isolated compounds were elucidated on the basis of NMR (H,C, COSY, HMBC, HSQC, and TOCSY), UV, FT-IR and LC-Q-TOF-MS spectrometric data.

Chemical composition, antimicrobial, and lipase enzyme activity of essential oil and solvent extracts from Serapias orientalis subsp. orientalis.

The volatile components of essential oil (EO), SPME, and SPME of solvent extracts ( -hexane, methanol, and water) obtained from fresh subsp. ( ) were analyzed by GC-FID/MS. EO of gave 11 compounds in the percentage of 99.

α-Glucosidase inhibitory effects of polyphenols from Geranium asphodeloides: Inhibition kinetics and mechanistic insights through in vitro and in silico studies.

Some Geranium species have been used to treat diabetes. To evaluate the scientific basis of this ethnopharmacological use, we aimed to isolate potent α-glucosidase inhibitory metabolites of Geranium asphodeloides Burm. through in vitro bioactivity-guided fractionation.
