From the leaves of Phlomis aurea, two new iridoids of unique structures named 3-epiphlomurin (1) and phlomurin (2), a new megastigmane glucoside phlomuroside (3) and a new benzyl alcohol glycoside having the structure benzyl alcohol-O-beta-xylopyranosyl-(1-->2)-beta-glucopyranoside (4) have been isolated together with four known iridoids auroside, lamiide, 8-epiloganin and ipolamiide, two known...
گیاهان مورد استفاده در این پژوهش از دو سرده phlomis l.با نام فارسی گوش بره یا فتیله ای و peroveskia l. با نام فارسی برازمبل انتخاب شدند که هردو متعلق به تیره نعناعیان می باشند.در پژوهش حاضر چهار نمونه از گونه های ph. elliptica،ph. persica و ph. rigidaجمعآوری و از 1/0 گرم آنهابا استفاده از متانل 80? و دو روش خیساندن و حمام امواج فراصوت عصاره گیری شد. سپس محتوای ترکیبات ساپونینی، فنلی، فلاونوئیدی...
Background and Aims: Acetaminophen is a common anti-analgesic and antipyretic medication that in high doses leads to liver and kidney necrosis in humans and animals. Phlomis cancellata, from the mint family, is a plant that has antioxidant properties. In the present study, the hepatoprotective effect of Phlomis cancellata hydroalcoholic extract on acetaminophen-induced hepatotoxicity in rats wa...
A new phenylethanoid tetraglycoside, physocalycoside (2), was isolated from the aerial parts of Phlomis physocalyx. Its structure was identified as 3-hydroxy-4-methoxy-beta-phenylethoxy-O-[alpha-L-rhamnopyranosyl-(1-->2)-alpha-L-rhamnopyranosyl-(1-->3)]-4-O-feruloyl-[beta-D-glucopyranosyl-(1-->6)]-beta-D-glucopyranoside, on the basis of spectroscopic evidence. In addition, one known iridoid glu...
Background and objectives: Phlomis bruguieri Desf. (Lamiaceae) is a perennial herbaceous plant distributed in Iran, Turkey and Iraq. Despite medicinal potentials of this species, the current knowledge on its phytochemical constituents is limited. The aim of the present study was to investigate the phytochemical constituents of the essential oil and various extracts of this species. Methods: Ess...
Green synthesis of metal nanoparticles is an interesting issue of nanoscience due to its simplicity and eco-friendliness. The present study describes a cheaper, non-toxic and simple route for biosynthesis of Silver nanoparticles using Phlomis cancellata Bunge extracts. Since the experimental conditions of this procedure play vital roles in the synthesis rate of the nanoparticles, a response sur...
In this study, we compared the impact of high Cu concentrations on the photosynthetic apparatus and antioxidant capacity of the Phlomis tuberosa. Plants were grown in perlite culture for 5 weeks, and then treated with 0, 100, 200, 300 and 400 µM Cu for 21 days. Results indicated that Phlomis tuberosa plants showed tolerance to 100 and 200 µM Cu. This increased tolerance was achieved through enh...
Due to the extensive area and biodiversity, rangelands contribute to meeting the nutritional requirements of grazing livestock; Therefore, a study was conducted to investigate the nutritional value of four range species including Malcolmia africana, Plantago lanceolata, Phlomis cancellata, and Klasea latifolia in the mountainous rangelands of Torbat-e Jam. The sampling of plants was randomly do...
