Embodiment approach 1

[0032] Use dark purple Fritillaria from Xining and Maqin in Qinghai, Gansu Fritillaria from Guide, Qinghai Xining, and Luhuo in Ganzi Prefecture, Curly-leaf Fritillaria from Kangding County, Sichuan, and Susia Fritillaria from Huding County, Sichuan Each of the 6 samples was used as the object, and about 1.2g of the crushed fritillary mother sample (passed through a 80-mesh sieve) was weighed, and 15ml of methanol was added, weighed, refluxed in a water bath at 55°C for 90min; weighed again, and made up to before the water bath weight, filtered, discarded the initial filtrate, took 10ml of the continued filtrate, concentrated to dryness under reduced pressure, and dried in vacuum for 30 minutes; the residue was washed with 0.05ml DMSO-d 6 Dissolved, transferred to f5mm nuclear magnetic tube, that is available for 1 Sample solution for H-NMR spectrum determination.

Abstract

The invention relates to a method for identifying and evaluating bulbus fritillariae cirrhosae, wherein four types of pharmaceutically acceptable bulbus fritillariae cirrhosae are used as objects; the total extractives of the four types of bulbus fritillariae cirrhosae are used as analysis objects; 1H-NMR (Nuclear Magnetic Resonance) is used as a detection means; principal component analysis or minimum partial least square is used as a data processing method; and the 1H-NMR data of the total extractives of the four types of bulbus fritillariae cirrhosae are used as a base for judging whether the unknown bulbus fritillariae cirrhosae sample belongs to the pharmaceutically acceptable bulbus fritillariae cirrhosae sample or not.

Description

technical field [0001] The invention relates to a method for identifying and evaluating Chinese medicinal material Fritillaria sichuanensis. Background technique [0002] Chuan Fritillaria is sweet, slightly bitter, and has the effect of clearing away heat and moistening lung, reducing phlegm and relieving cough. [1] . There are 60 species, 45 varieties and 5 varieties of Fritillary plants discovered so far. The four base species of Fritillaria fritillata recorded in the 2005 edition of Pharmacopoeia are Fritillary fritillata (Fritillary fritillaria) of the Liliaceae plant Fritillaria cirrhosa , dark purple fritillary F. unibratata , Gansu Fritillaria F. przewalskii fritillaria F. delavayi dried bulbs of [2] . The former three are commonly called "Songbei" and "Qingbei" respectively according to their different characters, and the latter are commonly called "Lubei". Examine from plant sources [3] , curly leaf fritillary is mainly produced in Sichuan, Tibet, Yunna...
