the present study was designed to explore the flavonoid contents and the radical scavenging activities of 50% ethanol extracts of leaves, stems, rachis and roots of dryopteris erythrosora. the total flavonoid contents in various parts were determined as: stems > roots > rachis > leaves. all extracts from different parts of d. erythrosora showed strong bioactivities. the dpph free radical scaven...

Nitrogen fertilizer application rates in intensive agricultural systems have increased dramatically in recent years, especially in protected vegetable production systems. This excessive use of nitrogen fertilizer has resulted in soil secondary salinity, which has become a significant environmental stress for crops such as cucumber, in the protected farmlands. It is thus necessary to illuminate ...

In this study we have demonstrated the variations of carbohydrates and phenolic compounds present in the leaves and stems of ‘Kinnow’ mandarin (Citrus reticulata Blanco) trees in alternate bearing cycle and the possible involvement of these compounds to flower bud formation process. The amounts of these compounds were determined in the leaves and stems of “on” and “off” trees  monthly  from Nov...

Volatile components of three parts of Pimpinella tragium Vill. (Umbelliferae family) from Iran were investigated qualitatively and quantitatively for the first time. Essential oils were isolated by hydro-distillation from stems plus leaves, inflorescence and seeds of P. tragium individually. The plant materials were collected from Polour (Northeast of Tehran Province). The yields of the ...
