در این تحقیق به منظور ارزیابی عملکرد آنتی اکسیدانی و ترکیبات فنلی عصاره های آبی و هیدروالکلی گیاه آنغوزه (.ferula assa-foetida l)، صمغ گیاه از رویشگاه طبیعی آن واقع در شهرستان بیرجند (1470 متر) جمع آوری شد. عصاره ها با روش خیساندن، اندازه گیری میزان فنل کل با استفاده از معرف فولین سیکالتو برحسب میلی گرم بر گرم اسیدگالیک و فعالیت آنتی اکسیدانی نیز به روش اسپکتوفوتومتری براساس میزان مهار رادیکال ...
Objective- Cutaneous wound healing is an essential physiological process consisting of the collaboration of many cell strains and their products. Initiation of new management for treatment of wound infections caused by multidrug resistant Staphylococcus aureus is required. The aim of the present study was to assess wound healing activity of Ferula assa-foetida...
Dormancy and germination response of Galbanum seeds (Ferula gummosa) under different hormonal pre-treatments cold stratification
Fractionation of methylene chloride extracts of the resin of Ferula vesceritensis and F. sinaica afforded three sesquiterpene coumarins and a glucose derivative. One of them was a sesquiterpene with a rare carbon skeleton. The structures of these compounds were determined by extensive NMR studies, including DEPT, COSY, NOE, HMQC, and HMBC.
در این مطالعه، زمان انشقاق عنصر بزرگ آسیایی Ferula L. متعلق به زیرطایفه Ferulinae، طایفه Scandiceae، و تیره چتریان (Apiaceae) توسط توالیهای ناحیه (ITS (Internal transcribed spacer ژنوم هسته و سه ناحیه کلروپلاستی غیرکدکننده (اینترون rps16 و اینترون rpoC1 و ناحیه بین ژنی rpoB-trnC ) تخمین زده شد. دادههای حاصل از 141 تاکسون زیرطایفه (Ferulinae (Ferula, Dorema, Leutea به همراه گونههای خویشاوندشا...
Ferula gummosa Boiss. (Apiaceae) is one of the natural plants of Iran. The whole plant, but especially the root, contains the gum resin "galbanum". A study of the comparative effects of galbanum gum and two standard binding agents--polyvinylpyrolidone and acacia--on characteristics of acetaminophen and calcium carbonate compacts was made. The Ferula gummosa gum was extracted and its swelling in...
Dormancy and germination requirements were investigated in seeds of Ferula gummosa Boiss (Apiaceae) and Teucrium polium L. (Labiatae). Seeds of both species were subjected to different treatments including various levels of GA3, HNO3, H2SO4, chilling and soaking with water at different temperatures. Germination of both species increased at higher concentrations of GA3. In the case of F. gummosa...
The present work describes the phytochemical study on Ferula lutea flowers. Total phenolics and flavonoids of the n-butanol and ethyl acetate extracts were quantified (phenolics [40.68-52.29 mg gallic acid equivalent/g of dry weight], flavonoids [12.38-14.72 mg quercitin/g dry weight]). Two diastereoisomers were isolated and identified using spectroscopic techniques (1D, 2D NMR and GC-MS). The ...
