Embodiment 1

[0040] Example 1: Extraction, separation and structure confirmation of ursane-type triterpene saponin compounds A, B, and C

[0041] Extraction and separation: Sanguisorba officinalis L. was purchased from Chengdu Traditional Chinese Medicine Company and identified as Sanguisorba officinalis L. Take 20kg of Burnet herb, cut into slices, extract twice with 8 times the amount of 70% ethanol, each time for 1 hour, filter, recover the ethanol, add water to 0.3g crude drug / ml, refrigerate for 12 hours, take the supernatant and absorb it through the macropores resin. Wash with water until the Molish reaction is negative, then elute with 70% ethanol, collect the eluate, recover ethanol, and concentrate to obtain a thick extract. Add 25L of hot water to the concentrated extract and stir thoroughly, and filter out the precipitate (about 4kg, mainly tannins detected by TLC). The filtrate was extracted three times with equal volumes of ethyl acetate and n-butanol respectively, then con...

Description

Technical field: [0001] The present invention relates to a new use of a compound, in particular to the use of an ursane-type triterpene saponin compound in the preparation of medicines for preventing or treating human leukopenia and (or) thrombocytopenia. Background technique: [0002] Human leukopenia is a common clinical disease and frequently-occurring disease. Generally, chronic leukopenia has no special symptoms, but some patients may experience mild fatigue, dizziness, low-grade fever, and oral ulcers. When leukopenia is severe, various infections can occur, such as respiratory tract infection, bronchitis, pneumonia, otitis media, and urinary system infection. There are many factors that cause leukopenia, and the common ones include the following aspects: First, leukopenia caused by various therapeutic drugs, such as tumor chemotherapy drugs, antipyretic analgesics, sulfa drugs, antithyroid drugs, and antiallergic drugs. It may cause leukopenia in human body; secondly...
