چکیده

the aim of this study was to assess the effect of several doses of spearmint essential oil (seo; 0, 250, 500, 750 or 1,000 µg ml-1 buffered rumen fluid) on the fermentation kinetic and digestibility using in vitro gas production technique. a total mixed ration (30% roughage: 70% concentrate) was incubated with buffered rumen fluid. in vitro gas production, asymptotic gas production (a), rate of gas production (µ), partitioning factor (pf), microbial biomass (mb), ammonia concentration and digestibility were determined. increasing the dose of seo decreased the parameters a and µ. adding seo, however, increased pf, ammonia concentration, apparent in vitro dry matter digestibility and true in vitro organic matter digestibility at the lower levels of seo (250 and 500 µg ml-1). but, at the level of 1,000 µg ml-1, a decrease was observed for these parameters. the increment in pf and digestibility illustrate that seo has a potential to modulate the rumen fermentation, which may be beneficial (at low doses) for improving nutrient utilization.

Environmental Factors Affecting the Accumulation of Rosmarinic Acid in Spearmint (Mentha spicata L.) and Peppermint (Mentha piperita L.)

Four spearmint, and two peppermint clonal lines, selected for enhanced rosmarinic acid content (50-120 mg g -1 rosmarinic acid DW), where up to 80% of the antioxidant activity was correlated to rosmarinic acid content, were examined to determine the effects of environmental and physiological conditions on the accumulation of rosmarinic acid in leaf tissues. Exposure to a short photoperiod of 12...

Phenolic and Volatile Composition of a Dry Spearmint (Mentha spicata L.) Extract.

The present paper reports a complete mass spectrometric characterization of both the phenolic and volatile fractions of a dried spearmint extract. Phenolic compounds were analysed by ultra-high performance liquid chromatography-electrospray ionization-mass spectrometry (UHPLC-ESI-MS(n)) and a total of 66 compounds were tentatively identified, being the widest phenolic characterisation of spearm...
