Chlorogenic acid, a pharmacologically important compound, is a phenolic compound that occurs in certain commonly used medicinal herbs. We looked for the presence of this compound in the callus cultures of Varthemia persica DC (var. persica). We have evaluated the conditions for establishment of callus cultures of V. persica and the in vitro production of chlorogenic acid. Callus was initiated b...
گیاه عطرسنگ(varthemia percica dc) گیاهی معطر از خانواده کاسنی (compositae) است که تنها گونه ی موجود در ایران و انحصاری فلات ایران می باشد. این گیاه از نواحی اطراف بیرجند جمع آوری شد. قسمت های ریشه و اندام های هوایی (ساقه و برگ) به طور جداگانه خشک گردید. عصاره ی متانولی هر قسمت جداگانه توسط دستگاه سوکسله تهیه شد ، و بعد از استخراج به وسیله ی تکنیک های ft-ir و uv مورد بررسی قرارگرفتند . محلول های...
To assess the clinical utility of the crude ethanolic extract of the leaves of Varthemia iphionoides (Compositae), minimal inhibitory concentrations eJ'v1Ies) were determined using agar dilution technique. Accordingly, The MICs of of this plant extract ranged from 0.0313-1 mg/ml for three clinical Staphylacaccus aureus strains and ATCC strains of Bacillus subtilis and Staphylococcus epidermidis...
the volatile constituents of the aerial parts of varthemia. persica dc. var. persica, growing wild in iran, were investigated by gc-ms. sixty seven constituents were identified. ?-cadinene (9.7%), selin-11-en-4-?-ol (5.30%), germacrene d (4.9%), bicyclogermacrene (4.7%), ??muurolene (4.7%), ?-eudesmol (4.52%), ?-himachalen oxide (3.6%), ?-eudesmol (3.54%), ?-bourbonene (3.21%) were found to be ...
سابقه و هدف: گیاه عطر سنگ گیاهی معطر از خانواده کاسنی و انحصاری فلات ایران می باشد. این گیاه حاوی روغن های فرار بوده، در بررسی روغن فرار گیاه مشخص گردید که اصلی ترین مواد متشکله روغن فرار سزکویی ترپن ها (sesquiterepens) می باشد. تاکنون هیچگونه مطالعه ای در زمینه فلاونوییدهای این گیاه منتشر نشده است.مواد و روش ها: از پودر گل، میوه و اندام هوایی که توسط فریز درایر خشک گردیده بود توسط متانول آبکی ...

cell cultures of varthemia persica, peganum harmala and pycnocycla spinosa have been studied to evaluate their abilities to bioconvert exogenous hydroquinone. arbutin is an important substance that has several pharmaceutical applications; therefore, we have established v. persica and p. spinosa cultures which seem to be able to metabolize hydroquinone. callus cultures of v. persica were establi...
cell cultures of varthemia persica dc. have been studied to evaluate their abilities in biotransformation of aromatic and aliphatic precursors. v. persica (asteraceae) is an aromatic plant growing in iran. v. persica contain different terpens but its cell culture does not posses these compounds. callus cultures of v. persica was established from seedlings and healthy suspensions were grown usin...
