this experiment was set to study the allelopatic effect of aqueous and alcoholic extracts of artemisia, coriander, eucalyptus and cumin on growth of red root pigweed and lambsquarters weeds at laboratory and field in the university of tehran (karaj-iran) in 2008. the herbal plant samples were ground and powdered for extraction preparation, and were mixed with distilled water in a beaker. the ex...

The role of lipids in the process of embryonic development of Caenorhabditis elegans is still poorly understood. Cytochrome P450s, a class of lipid-modifying enzymes, are good candidates to be involved in the production or degradation of lipids essential for development. We investigated two highly similar cytochrome P450s in C. elegans, cyp-31A2 and cyp-31A3, that are homologs of the gene respo...

in the course of study on larval parasitoids of carob moth, ectomyelois ceratoniae zeller (lep.: pyralidae), an hyperparasitoid wasp, pachycrepoideus vindemmiae rondani, was collected from pupae of apanteles sp. (hym.: braconidae). the latter species is the larval parasitoid of the carob moth. the p. vindemmiae belongs to the family pteromalidae and is a new record for iran insect fauna.

Hippophae rhamnoides L. and Cassia fistula L. extracts have great potential as food, medicinal, or cosmetic ingredients. The aim of our study was to assess their relative antioxidant activities and key enzymatic activities. Thereby, H. rhamnoides’ fruit and C. fistula’s pod extracts were evaluated by spectrophotometry, based on their respective total phenolic content (TPC), 2,2-diphenyl-1-picry...

The aims of this study were to determine the proximate composition of cacao pod husk as well as the optimal conditions for extraction and purification of theobromine from cacao pod husk. The results indicated that cacao pod husk had high contents of moisture and carbohydrate (87.06% and 11.03% by fresh weight, respectively), but low contents of crude protein, crude lipid, and ash (0.31%, 0.12%,...

Mature seeds of carob tree (Ceratonia siliqua L.) were germinated on hormone free MS medium. Efforts were made to develop multiple shoots by using axillary buds of in vitro grown seedlings on MS medium fortified with different concentrations of BA singly and BA in combination with IAA or GA3. Axillary buds produced single shoot with a moderate amount of callus at the base of the explant after c...

The present work studied low-cost carbon sources for carotenoid and lipid production using the yeast Rhodosporidum toruloides NCYC 921. Carob pulp syrup and sugarcane molasses at different concentrations were used as low-cost carbon sources in R. toruloides batch cultivations. Carob pulp syrup containing a total sugar concentration of 75 g L(-1) induced the highest total fatty acid productivity...
