Identification of Ternate Pinellia (Pinellia ternata),Yunnan Jackinthepulpit (Arisaema yunnanense) and Whipformed Typhonium (Typhonium flagelliforme) by UV-Spectrometry / 中草药

ABSTRACT

Alcoholic (70%) extract of Pinellia ternate, Arisaeme yunnanense and Typhonium flagelliforme were analysed by UY-spectrometry. Results showed that each of them had its own characteristics spectrum and was repcatable. This provides a method for the identification of three kinds of drug.It was discovered that the wavelength of maximum absorbance showed aggreement,when P.ternata from different origin were analysed by UV-spectrometry.
