We isolated 8 novel 28-noroleanane-derived spirocyclic triterpenoids with unusual skeleton structures, phlomisone (1), phlomistetraol A (2), phlomistetraol B (3), phlomistetraol C (4), phlomispentaol (5), phlomishexaol A (6), phlomishexaol B (7), and phlomisin (8), from the ethanol extract of Phlomis umbrosa rhizomes. Their structures were elucidated on the basis of spectroscopic methods, inclu...
تحقیق حاضر عدد کروموزومی هفت گونه متعلق به پنج خانواده از ایران را گزارش میکند. شمارش کروموزومی برای چهار گونه شامل: Tanacetum dumosum (2n=18), Phlomis elliptica (2n=20), Alcea aucheri (2n=42) و2n=20)) Phlomis aucheri برای اولین بار گزارش میشود. همچنین سطح تتراپلوییدی (2n=4x=32) برای گونه Fibigia umbellata نیز برای نخستین بار ارایه شده است. پارامترهای کروموزومی آنها بررسی شد و ایدیوگرا...
The selected parts of four medicinal plants, Achillea millefolium, Hibiscus rosasinensis, Linum usitatissimum and Pluchea lanceolata were extracted in absolute methanol to determine their analgesic activity. Analgesic activity was assessed on intact mice by tail flick latency via the tail immersion method. The analgesic activities of these plant extracts were compared with acetylsalicylic a...
In 2009, the Global Asthma and Allergy European Network (GALEN) proposed a pan-European standardized allergen battery for clinical practice and research [1]. While Parietaria species sensitization is an unquestionable cause of seasonal allergy in Mediterranean countries [2], and as such is included in this battery, Plantago lanceolata is widely considered to be a rare, isolated cause of hay fev...
Essential oils of Duguetia lanceolata barks, obtained at 2 (T2) and 4 h (T4), were identified by gas chromatography and gas chromatography/mass spectrometry. β-elemene (12.7 and 14.9%), caryophyllene oxide (12.4 and 10.7%) and β-selinene (8.4 and 10.4%) were the most abundant components in T2 and T4, respectively. The essential oils inhibited the growth of Staphylococcus aureus, Streptococcus p...
From the aerial parts of the plant Phlomis chimerae, a new neolignan glucoside, (-)-4-O-methyldihydrodehydrodiconiferyl alcohol-9'-O-beta-D-glucopyranoside (1) was characterized along with the known neolignan glucosides, (-)-4-O-methyldehydrodiconiferyl alcohol-9'-O-beta-D-glucopyranoside (= longifloroside A) (2) and (-)-dihydrodehydrodiconiferyl alcohol-9-O-beta-D-glucopyranoside (3). The stru...
background: several therapeutic effects including anti-asthma and dyspnea have been described for plantago lanceolata . in the present study the antitussive effect of this plant was evaluated. methods: the antitussive effects of aerosols of two different concentrations of soxhlet and macerated ethanolic extracts, codeine and saline were tested by counting the number of coughs produced due to ...
