Embodiment 1

[0151] Embodiment 1: Capsules

[0152] Cut 9900g of dried day lily into 2-3 cm long sections, soak in 95% ethanol overnight. Heating and extracting with 95% ethanol for 3 times, timing from boiling, the time is 40min, 30min, 30min respectively, filtering, combining the filtrates, recovering ethanol, and obtaining extract A. The residue was heated and extracted twice with 60% ethanol for 40 minutes each time, filtered, the filtrates were combined, and the ethanol was recovered to obtain the extract B. Dilute the extract A with distilled water, filter, pass through the treated AB-8 macroporous resin column, wash with distilled water until the effluent is transparent, elute with 60% ethanol for 3 times the column volume, recover ethanol, and obtain sample 1. Treat extract B in the same way to get sample 2. Sample 1 is 64.3101g, and Sample 2 is 60.9338g. The cream yield is greater than 1.265%. Take the dried extract, add lactose (or starch, or dextrin) at a ratio of 1:0-5, mix ...
