in order to optimize callus induction in pistacia atlantica desf. subsp. kurdica rech. f., the effect of different plant growth regulator (pgr) combinations were studied. inflorescence axis explants were cultured on wpm medium supplemented with 1, 2 and 3 mg/l of tdz or 1, 2 and 3 mg/l of ba, in combination with 1mg/l different auxins: 2, 4-d,  naa  and iba . callus initiation was observed in a...

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...

eight salvia l. species including s. spinosa l., s. reuterana boiss., s. macrosiphon boiss., s. syriaca l., s. nemorosa l., s. virgata jacq., s. sharifii rech. f. & esfand. and s. mirzayanii rech. f. & esfand. were studied for flavonoid compounds. these constituents were analyzed using two-dimensional maps on silica gel 60f thin layer chromatography. the flavonoid compounds of each spec...

The cytotoxic chloroform fraction of Euphorbia aellenii Rech. F. (Euphorbiaceae) afforded two new phorbol diterpenoids: 4-deoxy-4α-phorbol-12-(2,3-dimethyl) butyrate-13-isobutyrate and 17-hydroxy-4-deoxy-4α-phorbol-12-(2,3-dimethyl) butyrate-13-isobutyrate. Their structures were elucidated by NMR and other spectroscopic methods. The immunomodulating potentials of the isolated compounds were tes...
