Oxalate and silica are considered antinutrients. Large quantities of oxalate and silica in plants can interfere with the uptake of essential minerals in ruminants. Therefore, the aim of this study was to compare the total silica and oxalate contents of seven varieties of Napier grass to find out which is best for cultivation. Taiwan, Zanzibar, Pakchong, Purple, Kobe, Indian, and Dwarf Napier grass were grown in a completely randomized design with three replications to determine their soluble oxalate, total oxalate, and silica contents. Plants were harvested at two months of plant maturity. Whole plant of the Dwarf Napier grass contained significantly higher soluble oxalate content than tall varieties. Total oxalate content in whole plant differed significantly among varieties. Dwarf showed the highest total oxalate content (3.23% dry matter (DM)) followed by Kobe (2.61%), Zanzibar (2.60%), Purple (2.44%), Taiwan (2.43%), Indian (2.15%), and Pakchong (1.95%). Regardless of variety, leaf tissue contained significantly higher soluble oxalate and total oxalate than stem tissue. There were no differences in silica content among them. In conclusion, the tall varieties could produce lower levels of soluble oxalate than the Dwarf variety, whereas silica content might not vary among them.Keywords: botanical fractions, mineral bioavailability, ruminant

The research was designed to understand the effect of addition of extract citrus on the antioxidative activity of green tea and to determine the optimum temperature  at the process of green tea extraction to get the best antioxidative activity.Two treatment factors were arranged in completely randomized design with three replications. First treatment factor was the temperature extraction of green tea consisted of 30, 60 and 100 oC, whereas the second treatment factor was concentration of extract citrus consisted of 0.0, 0.2, 0.4, 0.6, 0.8 and 1 %. The contents of polyphenol, tannin, total  acids were chemically determined, whereas antioxidative activity was determined by radical scavenging affect (RSA). Data were analyzed using analysis of variance (ANOVA) and Duncan’s Multiple Range Test (DMRT) if there was a significant difference in treatment effects.The research’s results show that there was insignificant interaction between temperature extraction of green tea and concentration of added extract citrus. Eventhough concentration of extract citrus did not significantly affect the contents of polyphenol and tannin but it affected significantly the contents of total acids and antioxidative activity of extract tea. The antioxidative activity at the concentration of extract citrus of 0.2 % was significantly greater than without extract citrus (as check treatment). The following increase in concentration of extract citrus until 1 % did not significantly increase in antioxidative activity. The temperature of tea extraction affected significantly on the contents of  polyphenol, tannin, total acids, and antioxidative activity of extract green tea. The highest values were obtained  at 100 oC and the the lowest at 30 oC. Temperature extraction of green tea of 100 oC and the addition of 0.2 % extract citrus was the optimum condition. At this condition,  the extract green tea contained polyphenol, tannin, total acids, and antioxidative activity as high as  13.77, 12.77, 0.69 and 93.37 %, respectively.
