Crocus cancellatus subsp. damascenus stigmas: chemical profile, and inhibition of α-amylase, α-glucosidase and lipase, key enzymes related to type 2 diabetes and obesity.

Spices are appreciated for their medicinal properties besides their use as food adjuncts to enhance the sensory quality of food. In this study, Crocus cancellatus subsp. damascenus was investigated for its antioxidant activities employing different in vitro systems.

Bisabololoxide derivatives from Artemisia persica, and determination of their absolute configurations by ECD.

Five antiplasmodial bisabololoxide sesquiterpene diesters were isolated from an EtOAc extract of the aerial parts of Artemisia persica following an HPLC-time-based activity profiling of the extract. Structure elucidation was achieved by 1D and 2D NMR experiments. Relative configurations of cyclohexenone/cyclohexene and tetrahydropyran moieties of 1-5 were established on the basis of ³J(H-H) coupling constants and NOE difference spectra.

Angiotensin-converting enzyme inhibitory activity and antioxidant properties of Nepeta crassifolia Boiss & Buhse and Nepeta binaludensis Jamzad.

This article reports phytochemical and biological studies on Nepeta binaludensis and Nepeta crassifolia. Both species were investigated for their angiotensin-converting enzyme (ACE) inhibitory activity and antioxidant properties through three in vitro models [2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and ferric reducing antioxidant power (FRAP) assay]. Aerial parts were extracted with methanol and partitioned between water and subsequently n-hexane, ethyl acetate and n-butanol.

Salvia leriifolia Benth (Lamiaceae) extract demonstrates in vitro antioxidant properties and cholinesterase inhibitory activity.

The object of the present study was to investigate the in vitro antioxidant properties and cholinesterase inhibitory activity of Salvia leriifolia Benth extracts and fractions. The functional role of herbs and spices and their constituents is a hot topic in food-related plant research. Salvia species have been used since ancient times in folk medicine for cognitive brain function and have been subjected to extensive research.

Comparative chemical composition and antiproliferative activity of aerial parts of Salvia leriifolia Benth. and Salvia acetabulosa L. essential oils against human tumor cell in vitro models.

The aim of this work was to examine the chemical composition and antiproliferative activity of Salvia leriifolia Benth. and Salvia acetabulosa L. oils.

In vitro biological activity of Salvia leriifolia benth essential oil relevant to the treatment of Alzheimer's disease.

In this study the chemical composition, cholinesterase inhibitory property and anti-inflammatory activity of S. leriifolia Benth. essential oil was evaluated for the first time.

Hypoglycaemic activity of two spices extracts: Rhus coriaria L. and Bunium persicum Boiss.

The hypoglycaemic efficacy of sumac (Rhus coriaria L.) and black cumin (Bunium persicum Boiss) extracts were investigated through inhibition of a glycoside hydrolase: alpha-amylase. On the basis of our result ethyl acetate extract of sumac may have interest in the treatment and prevention of hyperglycaemia, diabetes and obesity, with an IC50 value of 28.
