Embodiment 1
[0065] Embodiment 1: the TLC identification method of Naozhenning Granules
[0066] According to standard WS 3 -B-3312-98 prepares sucrose-containing Naozhenning granules, and uses the identification method provided by the present invention to identify them.
[0067] Prescription: Angelica 200g, Dihuang 200g, Moutan bark 150g, Chuanxiong 150g, Dilong 150g, Salvia miltiorrhiza 375g, Poria cocos 250g, Tangerine peel 250g, Zhuru 250g, fried jujube kernel 250g, Baiziren 250g
[0068] Preparation method: the above eleven flavors, angelica, peony cortex, Chuanxiong, and tangerine peel are distilled to extract volatile oil, and the distilled aqueous solution is collected in a separate device; the dregs and the remaining seven flavors such as salvia miltiorrhiza are decocted twice, each time for 1.5 hours, and the decoction is combined. Filtrate, combine the filtrate with the above aqueous solution, concentrate to a clear paste with a relative density of 1.35-1.38 (55°C), add sucrose...

[0072] Embodiment 2: TLC identification method of Naozhenning Granules (without sucrose)
[0073] According to standard WS 3 - B-3312-98-1 prepares sucrose-free Naozhenning Granules, which are identified by the identification method provided by the present invention.
[0074] Prescription: Angelica 200g, Dihuang 200g, Moutan bark 150g, Chuanxiong 150g, Dilong 150g, Salvia miltiorrhiza 375g, Poria cocos 250g, Tangerine peel 250g, Zhuru 250g, fried jujube kernel 250g, Baiziren 250g
[0075]The above eleven flavors, angelica, Moutan cortex, Chuanxiong, and tangerine peel are distilled to extract volatile oils, and the distilled aqueous solution is collected in a separate device; the dregs and the remaining seven flavors such as Salvia miltiorrhiza are decocted twice, each time for 1.5 hours, and the decoctions are combined and filtered. Combine the filtrate with the above aqueous solution, concentrate to a clear paste with a relative density of 1.35-1.38 (55°C), add dextrin, gra...
Embodiment 3
[0078] Embodiment 3: TLC identification method of Naozhenning Capsules
[0079] Prescription: Angelica 220g, Rehmannia glutinosa 210g, Moutan bark 160g, Chuanxiong 140g, Dilong 130g, Salvia miltiorrhiza 330g, Poria cocos 260g, tangerine peel 260g, Zhuru 260g, fried jujube kernel 160g, Baiziren 160g
[0080] Preparation method: the above eleven flavors, angelica, peony bark, chuanxiong, tangerine peel are distilled to extract volatile oil, and then add other medicinal materials for water extraction. After water extraction, use 80% ethanol to precipitate twice, concentrate into a thick paste, add starch and mix Homogenize, granulate, dry and granulate, add the obtained volatile oil, and stir evenly to prepare 200 Naozhenning capsules, each containing 0.4g.
[0081] Identification: (1) Take 0.77g of the contents of Naozhenning Capsules, grind it finely, add 10mL of methanol, ultrasonicate for 10 minutes, filter, evaporate the filtrate to dryness, add 0.5mL of methanol to dissolve...
