Embodiment 1
[0078] Example 1: Preparation of DSS-A-N-30, an extract of Danggui Shaoyao Fang
[0079] The single herbs of Danggui Shaoyao Formula are prepared according to the common ratio, Angelica: Paeoniae: Poria cocos: Atractylodes macrocephala: Alisma: Chuanxiong (3:16:4:4:8:8) or after adding or subtracting part of the herbs to form a crude drug 1500 grams, add six times the weight of the crude drug in boiling water and decoct three times for 1.5 hours each time, filter, and concentrate under reduced pressure to an appropriate volume.
[0080] After dissolving in water, carry out HP-20 macroporous adsorption resin column chromatography, the ratio of resin column bed volume (ml) to sample amount (grams) is 5:1, then eluted with water and 30% ethanol in sequence, and eluted with 30% ethanol Parts were concentrated to remove alcohol and then freeze-dried to obtain DSS-A-N-30 (33.0 g) as a tan powder. It has the aforementioned qualitative response characteristics.

Embodiment 2
[0082] Example 2: Preparation of DSS-A-N-30, an extract of Danggui Shaoyao Fang
[0083] The single herbs of Danggui Shaoyao Formula are prepared according to the common ratio, Angelica: Paeoniae: Poria cocos: Atractylodes macrocephala: Alisma: Chuanxiong (3:16:4:4:8:8) or after adding or subtracting part of the herbs to form a crude drug 1500 grams, add six times the weight of the crude drug in boiling water and decoct three times for 1.5 hours each time, filter, and concentrate under reduced pressure to an appropriate volume.
[0084] After dissolving in water, carry out HP-20 macroporous adsorption resin column chromatography, the ratio of resin column bed volume (ml) to sample amount (gram) is 5: 1, then elution with water and 40% ethanol in sequence, 40% ethanol elution Parts were concentrated to remove alcohol and then freeze-dried to obtain DSS-A-N-30 (35.0 g) as a tan powder. It has the aforementioned qualitative response characteristics.

Embodiment 3
[0086] Example 3: Biological Activity Experiment of Danggui Shaoyao Prescription Extract
[0087] Unless otherwise stated, the DSS-A-N-30 used in Example 3 refers to the DSS-A-N-30 prepared in Example 1.
[0088] 1. Analgesic effect of DSS-A-N-30
[0089] 1. Effect of oral administration of DSS-A-N-30 on the number of writhing reactions in mice induced by acetic acid
[0090] Male Kunming mice, 22-26 g, were given the corresponding drug orally for 40 minutes, and then injected 0.6% acetic acid aqueous solution at a dose of 10 ml / kg intraperitoneally. After injecting the acetic acid solution for 5 minutes, observe and record the number of animal writhing within 15 minutes. The results showed that oral administration of DSS-A-N-30 could significantly reduce the number of writhing reactions in mice induced by acetic acid (Table 1).
