Inhibition of Extracts of Polygonatum verticillatum Rhizome: Augmented by its Isolated Compound, Santonin.
, phosphatase and protease (an enzyme involved in the progressive decomposition of the N contained in proteins) activity in soils treated with compost was greater than in soils that were not treated with compost (Crecchio et al., 2004).
The coating of urea with sulphur, urease
inhibitors and other biodegradable materials are the possible remedies to reduce N loss and enhance urea efficiency (Shaviv, 2001).
Dual specimens increase the diagnostic accuracy and reduce the reaction duration of rapid urease
AAM: arginin ammonification (mg N[H.sub.4.sup.+]-N [kg.sup.-1] soil [h.sup.-1]); ALP: alkalin phosphomonoesterase activity (mg PNP [g.sup.-1] soil [h.sup.-1]); ARS: arylsulphatase activity (mg PNP [g.sup.-1] soil [h.sup.-1]), LGL: L-glutaminase activity (mg N[H.sub.4.sup.+]-N [kg.sup.-1]soil [h.sup.-1]); LAS: L-asparaginase activity (mg N[H.sub.4.sup.+]-N [kg.sup.-1]soil [h.sup.-1]); URS: urease
activity (mg N[H.sub.4.sup.+]-N [kg.sup.-1] soil [h.sup.-1])
A number of synthetic compounds including imidazoles, hydroxamic acids, and phosphazenes are effective urease
inhibitors, but limited studies have been conducted on natural products (Ahmad et al.
The activities of soil urease
, phosphatase, saccharase, and catalase in loam and clay soil were shown in Figures 4, 5, 6, and 7 and Table 1.

gene cluster," American Journal of Physiology: Gastrointestinal and Liver Physiology, vol.
Keeping in view the antiulcer use of the plant, the current study was designed to investigate urease
inhibitory properties of crude methanolic extract, total flavonoidal and sterol contents, and aqueous fraction of aerial parts of the plant in vitro.
(2008), soil saccharase activity is positively correlated with total nitrogen and available phosphorus, and urease
activity is negatively correlated with the soil pH.
pylori status was determined using the rapid urease
test (Pronto Dry).
can act upon urea generating ammonia and thiocyanate.
