Problems solved by technology

[0003] Since the iron chopsticks in the "Quality Standards for Traditional Chinese Medicinal Materials and Ethnic Medicinal Materials in Guizhou Province" only have two items of microscopic identification and thin-layer identification, no content measurement items have been established, and the quality controllability is poor

Embodiment 1

[0116] Embodiment 1 of the present invention: the preparation of iron chopsticks extract (see figure 1 ):

[0117] Take iron chopsticks medicinal materials, crush them into coarse powder, extract 3 times with 8 times, 6 times, and 6 times 95% ethanol respectively, each time for 2 hours, to obtain 95% ethanol extract, and set aside; amount, 6 times the amount, and 6 times the amount of 50% ethanol were extracted 3 times, each time for 2 hours, to obtain a 50% ethanol extract; combine all the extracts, concentrate under reduced pressure, recover the solvent, dry at 70°C in vacuum, and then add an appropriate amount of water to disperse , sequentially extracted four times with petroleum ether and ethyl acetate respectively, concentrated the ethyl acetate extract under reduced pressure to obtain the ethyl acetate layer extract, and dried it.

Embodiment 2

[0118] Embodiment 2: the preparation of iron chopsticks extract:

[0119] Take the iron chopsticks medicinal material, crush it into coarse powder, extract twice with 8 times, 7 times, and 6 times the amount of 95% ethanol, each time for 3 hours, to obtain 95% ethanol extract, and set aside; amount, 7 times, 6 times of 50% ethanol extraction twice, 3 hours each time, to obtain 50% ethanol extract; combine all extracts, concentrate under reduced pressure, recover the solvent, vacuum dry, then add appropriate amount of water to disperse, and then use Petroleum ether and ethyl acetate were extracted 5 times each, and the ethyl acetate extract was concentrated under reduced pressure to obtain the ethyl acetate layer extract, which was dried.

Embodiment 3

[0120] Embodiment 3: the preparation of iron chopsticks extract:

[0121] Take iron chopsticks medicinal materials, crush them into coarse powder, extract 4 times with 8 times the amount of 95% ethanol, each time for 1.5 hours, to obtain 95% ethanol extract, and set aside; then extract the dregs with 8 times the amount of 50% ethanol for 4 times , 1.5h each time to obtain 50% ethanol extract; combine all extracts, concentrate under reduced pressure, recover the solvent, dry, then add appropriate amount of water to disperse, successively extract 3 times with petroleum ether and ethyl acetate respectively, and concentrate acetic acid under reduced pressure Ethyl extract, get ethyl acetate layer extract, and dry it.

Abstract

The invention discloses a Helleborus thibetanus extract, a separation method of effective components in the Helleborus thibetanus extract and compounds obtained by the separation method. The Helleborus thibetanus extract is obtained by the following steps: respectively extracting a Helleborus thibetanus medicinal material by the use of 95% ethanol and 50% ethanol which account for 6-8 times the weight of the Helleborus thibetanus medicinal material for 2-4 times, merging extracts, condensing and drying, adding water for dispersion, successively carrying out extraction by the use of petroleum ether and ethyl acetate, condensing an ethyl acetate extract, and drying. It is found through an experimental research that the ethyl acetate extraction part in the ethanol extract of the Helleborus thibetanus extract has good pain-suppressing and anti-inflammatory effects, and the ethyl acetate extraction part can be used in the preparation of an anti-inflammatory and pain-suppressing medicine; and 17 compounds are obtained by separation of the ethyl acetate extraction part, wherein two compounds are new compounds and 12 compounds are firstly obtained by separation of Helleborus thibetanus. The invention lays a foundation for establishing content determination items of the Helleborus thibetanus medicinal material and a medicinal preparation containing Helleborus thibetanus, is beneficial to raising quality standard and quality controllability of the Helleborus thibetanus medicinal material and lays a foundation for further development and utilization of Helleborus thibetanus.

Description

technical field [0001] The invention relates to an iron chopsticks extract, a method for separating effective components therein and a compound obtained therein, and belongs to the technical field of extraction and separation of effective components of traditional Chinese medicines. Background technique [0002] The iron chopsticks are the dried fine roots of Chimonanthus praecox (L.) link. and Chimonanthus nitsoliv., which are plants of the genus Chimonanthus praecox (L.) link. "Standard", also known as Yanmasang, smelly wax plum, wild wax plum, etc., has the effects of clearing away heat and detoxification, promoting blood circulation and dispelling addiction, reducing swelling and relieving pain. Swelling poison and bruises embolism. The records began in "Rescue Famine Materia Medica", which said: "It is mostly grown in the south, and it is also found in the north today. Its branches are quite like seasons, and its leaves are broad like peach leaves, with slightly thick ...
