Dihydroisocoumarins and Phenylglycosides from Scorzonera longiana, Their Antimicrobial Activities and Molecular Docking Studies.

Five new phenyl dihydroisocoumarin glycosides (1-5) and two known compounds (6-7) were identified from the butanol fraction of Scorzonera longiana. The structures of 1-7 were elucidated based on spectroscopic methods. Antimicrobial, antitubercular, and antifungal evaluation of compounds 1-7 were carried out using the microdilution method against nine microorganisms.

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.

Anatomical properties of Epilobium and Chamaenerion from a taxonomical perspective in Turkey.

In the present study, the anatomical features of stem, leaf, and fruit of 22 Epilobium L. and 4 Chamaenerion Séguier taxa were studied using light microscopy with the aim to find out taxonomically significant characters for the examined taxa. Principal component analysis indicated that the row number of collenchyma, presence of periderma and phloem fibers in the stem, the shape of midrib and idioblast, leaf type, and the shape of fruit in cross section are the most valuable anatomical traits delimiting the investigated taxa at generic and partly specific level.

Altitude Variation in the Composition of Essential Oils, Fatty Acid Methyl Esters, and Antimicrobial Activities of Two Subspecies of Primula vulgaris Grown in Turkey.

In this study, the changes caused by variation of altitude to the essential oils (EOs), fatty acid methyl esters (FAMEs), and antimicrobial activities of Primula vulgaris Huds. subsp. vulgaris (Pvv) and P.

Chemical constituents and antimicrobial activities of the essential oils from Sedum pallidum var. bithynicum and S. spurium grown in Turkey.

Chemical compositions of the essential oil of Sedum pallidum Bieb. var. bithynicum (Boiss.

Composition and antimicrobial activity of essential oils from Centaurea sessilis and Centaurea armena.

The essential oils of air-dried Centaurea sessilis and Centaurea armena obtained by hydrodistillation were analyzed by gas chromatography-mass spectrometry (GC-MS). Forty and twenty components were identified in the essential oils and the main component of these taxons was beta-eudesmol in the ratios of 12.4% and 19.
