BACKGROUND: Phytase enzyme (EC 3.1.3.8), is used to increase the availability of phosphorus in the feeding of monogastric animals. Increasing public attention to environmental issues, improving livestock nutrition and human health have led to considerable attempts to increase its activity or prevent its inhibition as a food additive. OBJECTIVES: Determination of inhibitory or activating effect of methanolic extract from aerial parts of some herbs, as rich sources of secondary metabolites. METHODS: Phytase was partially purified from wheat barn. After preparation of methanolic extracts from aerial parts of plants, their effects on phytase activity were measured at four concentrations of 0.001, 0.01, 0.1 and 1 mg/ml. Micro plate assays were performed at 405 nm. RESULTS: Among analysed plant samples, extracts from Pedicularis sibthorpii Boiss, Phlomis persica Boiss, Solenanthus Circinatus Ledeb, Stachys lavandulifolia Vahl, had appreciable inhibitory effect, while extracts from Astragalus caraganae Hohe, Hypericum scabrum L, Linum album Ky.ex Boiss, Valeriana sisymbriifolia Vahl, Euphorbia denticulate Lam, Rindera lanata (Lam.) Bge, had a considerable activation effect. CONCLUSIONS: According to the results of this report, plants with positive effect on phytase activity, could be used as food additive along with phytase to improve phosphoros uptake. On the other hand, plants with negative effect on phytase could be viewed as unwanted sources in monogastric animals feeding.
