Isolation and GC/MS quantitative determination of ursolic acid in the herb of Nepeta cataria var. citriodora have been performed. The content of this compound was in the range 0.95 ñ 1.30%. Daucosterol (βsitosterol 3-O-β-D-glucoside) was also isolated from the plant, in addition to small amounts of β-sitosterol, campesterol, α-amyrin and β-amyrin. The content and composition of essential oil in...

In this study, we aimed to determine chemical composition and antibacterial activities of Satureja hortensis and Calamintha nepeta against to 20 phytopathogenic bacteria causing serious crop loss. The essential oils of S. hortensis and C. nepeta were isolated by the hydrodistillation method and the chemical composition of the essential oils were analyzed by GC-MS. The antibacterial properties o...

OBJECTIVE To determine the effects of Tinospora crispa on serum glucose and insulin levels in healthy subjects and patients with type 2 diabetes mellitus. METHOD Serum from 10 healthy subjects and 10 diabetic participants, who had fasted overnight, were obtained every 30-60 minutes during the 3 hours of continued fasting and during the 3 hours after ingestion of 75 g of glucose with or withou...

Epilepsy is a neurological disorder characterized by unprovoked, recurring seizures that disrupts the nervous system and can cause mental and physical dysfunction. Based on the ethno pharmacological information of the plant, the methanolic and aqueous extracts of the flowers of Nepeta bractaeta was evaluated for its antiepileptic activity. The methanolic and aqueous extracts of the flowers of N...

Molecular markers, mainly DNA-based are potential tools for DNA barcoding and phylogenetic study. The plant species belonging to the Nepeta genus have important medicinal value because of the presence of nepetalactones, and they have been used to treat human diseases. We amplified nuclear and chloroplast gene loci to develop a DNA barcode and phylogenetic study of Nepeta deflersiana. Among the ...

Background and objectives: Many Nepeta species have been commonly used in Iranian folk medicine as tranquilizer, relaxant, carminative and restorative tonic for nervous and respiratory disorders. Inflammation is a problem in many diseases and has an important role in brain function that can cause neurodegenerative disorders. Inflamed glial cells can exacerbate neurodegenerative diseases by prod...

A β-glucan synthase gene was isolated from the genomic DNA of polypore mushroom Sparassis crispa, which reportedly produces unusually high amount of soluble β-1,3-glucan (β-glucan). Sequencing and subsequent open reading frame analysis of the isolated gene revealed that the gene (5,502 bp) consisted of 10 exons separated by nine introns. The predicted mRNA encoded a β-glucan synthase protein, c...

This study was carried out to investigate the potential use of the herb Pulicaria crispa in the biological control of different developmental stages of Bulinus truncatus, a major snail intermediate host of urinary schistosomiasis. Age-dependent susceptibilities of mature adult snails, immature snails, juveniles, and one-day old egg masses to aqueous extracts of Pulicaria crispa leaves collected...
