A field survey revealed on average 2-fold higher Mo levels in three hyperaccumulator Astragali compared to three nonaccumulator Astragali, which were not significantly different. Next, a controlled study was performed wher...

This study focuses on the subset selection problem of computational statistics and de- ploys rank-biserial correlation (RBSC) based deck generation algorithm (RBSC-SubGen) [1] in solving it. RBSC-SubGen is originally designed for automatically building a desired number vocabulary decks (out large corpus) with level word frequency relation, which shares many common aspects generic problem. In th...

Gypsophila hispida, sect. Hispidae, is reported for the first time from NW Iran. Illustrations, morphological and palynological descriptions and distribution are provided in detail, along with a key for the six taxa of subgen. Hagenia from Iran.  

This study carried out for determination and discrimination of intraspecific diversity of Astragalus verus and Astragalus glaucops by Eco-phytosociological method from west of Iran. In this order, application of Endogenous milieu (special station) for data collecting and then their analyzing permit us only determine existence of inter and intraspecific diversity. Then for determinating kind and...

Radix Astragali has been an important traditional Chinese herbal medicine for over 2000 years. It is derived from two plant species, namely, Astragalus mongholicus [Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao] and Astragalus membranaceus [Astragalus membranaceus (Fisch.) Bge.] (Leguminosae), according to the Pharmacopoeia of the People’s Republic of China.
