Abstract: The aerial part of Bidens parviflora Willd is well-known as Guizhencao in traditional Chinese folk medicine for the treatment of
ailments such as diabetes, hepatitis, enteritis, laryngitis, etc. The essential oil of B. parviflora was obtained by hydrodistillation
and further analyzed by GC-MS method. Physicochemical investigation was also carried out on this medicinal plant. The yield
of essential oil was 0.09% (v/w). Sixty-one constituents accounting for 89.37% of the total oil were identified and quantified. The
total ash value, acid-insoluble ash value, water-soluble, ethanol-soluble, ether-soluble extractive and moisture content values
are 8.75%, 1.25%, 25.87%, 19.85%, 0.30% and 9.41%, respectively. The pharmacognostical parameters could be used as the
diagnostic tool for the standardization of this medicine and the results also can be considered as the identifying parameters to
substantiate and authenticate the drug.
