Two flavones, ladanein and 6-hydroxy-5,7,4'-trimethoxyflavone and one labdane-type diterpene, ent-13-epi-manoyloxide, were isolated from an ethyl acetate-methanol extract of the aerial parts of Salvia sharifii. The compounds were purified using several chromatographic methods. Structural elucidation of the compounds was performed using their (1)H and (13)C-NMR data, EI mass and UV spectral data...

This study was designed to examine the chemical composition and in-vitro antioxidant activity of the essential oil and methanolic extract of Teucrium orientale subsp. taylori. The GC and GC-MS analysis of the essential oil resulted in determination of 40 components representing 96.4% of the oil. The major constituents of the oil were linalool (28.6%), caryophyllene oxide (15.6%), 1,8-cineol (4....

The current study evaluated the general toxicity, antioxidant, antimicrobial, and cytotoxic activity of extracts obtained from the rhizomes of Eremostachys azerbaijanica (Labiatae) as well as analyzed the potent extracts using GC-MS. Extracts of E. azerbaijanica in n-hexane, dichloromethane (DCM) and methanol (MeOH) were prepared using a Soxhlet apparatus. The antioxidant activity of the extrac...

A cikk a medvetalp (Heracleum) nemzetség néhány hazánkban gyűjtött, tévesen határozott, az MTM Növénytára herbáriumában (BP) őrzött példányát, illetve ezek szakirodalmi kapcsolatait tárgyalja. Az őshonos Heracleum taxonok Kárpát-medencei elterjedési mintázatát Simon Tibor tisztázta 1960-as években, szóban forgó példányokat azonban, amelyek valójában idegenhonos fajokat reprezentálnak, revideált...

Aerial parts of Salvia Mirzayanii was extracted with methanol. Methanol extract was suspended in water and defatted with petroleum ether. The defatted part was then partitioned between ethyl acetate and water. The ethyl acetate partition was chromatographed on a silica gel column to afford several fractions. Lymphocyte proliferation inhibitory assay of the resulted fractions was compared in vit...

Ecological study of behavior is essential elements of the renewable natural resources. The study area in this research was Deh Bala where is one of the main habitat of N. asterotricha Rech. f. This plant is one of the 34 endemic species of Nepeta L. in Iran. In the study area, different parameters were determined such as essential oil, climate factors, phenology, co-dominant plants, morphology,...
