Abstract

The invention discloses an identification method of herba patriniae in a Chinese herbal compound, and particularly relates to a thin-layer identification method of herba patriniae in a Chinese herbal compound. The identification method comprises the following steps of preparing a reference crude drug solution; preparing a test product solution; preparing a negative sample solution; performing sample application on the same silica gel G thin-layer plate with a capillary sample applicator; placing the thin-layer plate into a chromatographic jar, performing expansion with an expanding agent, taking out and drying the thin-layer plate in air; and inspecting a thin-layer chromatographic sheet to obtain a result for identification, wherein a main spot of the same color is developed at a position, which corresponds to a reference crude drug chromatography, on a test product chromatography, but no spot is developed on a negative sample. The identification method disclosed by the invention is simple in technology, good in separation effect and extremely high in specificity; and the accuracy of component identification of herba patriniae in the Chinese herbal compound is further improved, and the identification method has a huge popularization and application potential in the field of identification of herba patriniae-related medicines.

Description

technical field [0001] The invention relates to a method for identifying Patrinia in compound Chinese medicines, in particular to a TLC identification method for Patrinia in compound Chinese medicines. Background technique [0002] It is the dried whole plant of Patrinia scabiosaefolia Fisch. or Patrinia villosa Juss. of Patrinaceae. In summer, the flowers are collected before they bloom, dried in the sun until they are half-dried, tied into bundles, and then dried in the shade. Mainly produced in Jiangsu, Zhejiang, Hubei, Anhui. Patrinia has the effects of clearing heat and detoxifying, removing blood stasis and draining pus. Indications for appendicitis, dysentery, enteritis, hepatitis, conjunctivitis, postpartum blood stasis and abdominal pain, carbuncle and furuncle. Patrinia can also be combined with other medicinal materials to make a variety of compound Chinese medicines, such as Longqing Tablets recorded in a 2015 article, Patrinia Tablets, Fufang Fuyanping Capsul...
