An improved HPLC method for determination of colocynthin in colocynth
Background and objectives: Colocynthin is the major active secondary metabolite of colocynth, Citrullus colocynthis (L.) Schrad, which has been used in traditional and ethno medicine of many countries. It could be considered as an active marker for quality control of colocynth and its herbal products. Analysis and standardization of colocynth and its herbal preparations are a critical...
متن کاملDegree of polarization as an objective method of estimating scattering.
A new method of determining objectively the amount of scattered light in an optical system has been developed. It is based on measuring the degree of polarization of the light in images formed after a double pass through the system. A dual apparatus composed of a modified double-pass imaging polarimeter and a wave-front sensor was used to measure polarization properties and aberrations of the s...
متن کاملAn improved method for measuring blood concentrations of phenylpyruvic acid.
We describe an improved determination of phenylpyruvic acid (PPA) in blood plasma by ultraviolet spectrophotometric measurement of an enolborate complex. Sensitivity and recovery are well suited for accurate analy. sis in the range of 1.25 to 25 mg/liter. Sera from 10 fasting phenylketonuric subjects averaged 15.3 mg/liter (range, 4.8 to 25.0 mg/liter). A pronounced diurnal rhythm in plasma PPA...
متن کاملAn improved noninvasive method for measuring heartbeat of intertidal animals
Since its emergence two decades ago, the use of infrared technology for noninvasively measuring the heartbeat rates of invertebrates has provided valuable insight into the physiology and ecology of intertidal organisms. During that time period, the hardware needed for this method has been adapted to currently available electronic components, making the original published description obsolete. T...
