Embodiment 1

[0023] (1) 1 kg of Phyllanthus phylloxera, add 5 kg, 30% ethanol, heat and extract at 80° C. for 3 hours, filter, and then use the above-mentioned solvent to repeatedly extract the filter residue twice, filter, and combine the filtrates to 2 / 3 of the original volume in vacuum at 60° C. Add D101 macroporous resin to adsorb for 24 hours; take out the macroporous resin and elute with 90% ethanol, concentrate the eluate in vacuum at 50°C to 1 / 3 of the original volume, extract once with an equal volume of dichloromethane, combine the extracts, Concentrate in vacuo at 30°C and dry for 3 hours to obtain 55 g of anti-influenza virus effective fraction of Phyllostachys phylloxera.

[0024] (2) Acrylic resin IV100g is mixed with the capsule material solution of 5% mass fraction with dichloromethane, adds capsule material solution mass fraction 0.5% monoglyceride, 0.1% polyethylene glycol, 20% Phyllostachys anti-influenza virus The effective part is ultrasonically emulsified for 0.5 hour...

Embodiment 2

[0026] (1) 1 kg of Phyllanthus phylloxera, add 10 kg of 80% ethanol and extract by heating at 30°C for 1 hour, filter, and then repeat the extraction once with the above solvent, filter, combine the filtrate and concentrate it in vacuum at 30°C to 1 / 3 of the original volume, add DM130 The macroporous resin was adsorbed for 8 hours; the macroporous resin was taken out and eluted with 50% ethanol. When the eluate was concentrated in vacuum at 60°C to 2 / 3 of the original volume, it was extracted 3 times with an equal volume of ethyl acetate, and the extracts were combined at 50°C. Concentrate in vacuo and dry for 3 hours to obtain 102 g of anti-influenza virus effective fraction of Phyllostachys phylloxera.

[0027] (2) ethyl cellulose 100g is mixed with acetone to form a 10% mass fraction of the capsule material solution, add the capsule material solution mass fraction 5% Tween 80, 0.5% talc, and 10% Phyllophyllum anti-influenza virus effective fraction, Ultrasonic emulsificatio...

Abstract

The invention discloses micro-capsules of an anti-influenza-virus effective part of phyllanthus urinaria, and a preparation method and application thereof. The preparation method comprises the following steps of: heating and extracting phyllanthus urinaria medicinal materials by using 30 to 80 percent ethanol, recovering the ethanol from an extracting solution, adsorbing by using a macroporous resin, eluting by using 50 to 90 percent ethanol, recovering the ethanol, and extracting the effective part by using dichloromethane, ethyl acetate or n-butyl alcohol; mixing capsule materials, emulsifier, an antisticking agent and a solvent to obtain a mixed solution, adding an aqueous solution of the effective part of the phyllanthus urinaria into the mixed solution, performing ultrasonic emulsification, allowing the mixture to pass through a microfiltration membrane, and spray-drying to obtain the micro-capsules. The micro-capsules can kill influenza virus and can be used for anti-influenza-virus medicines or disinfection of epidemic prevention articles for human or animals. The micro-capsules improve the stability of the effective part of the phyllanthus urinaria and improve the action effect of the effective part obviously.

Description

technical field [0001] The invention relates to the field of pharmaceutical manufacturing, in particular to a method for preparing a microcapsule of the anti-influenza virus effective part of Phyllostachys phylloxera and its application as an antiviral drug. Background technique [0002] Phyllanthus urinaria L is a plant of the genus Phyllanthus urinaria in the family Euphorbiaceae. It is cool in nature, slightly bitter and sweet, and has the effects of calming the liver, annealing, improving eyesight, detoxifying and reducing swelling. Infantile malnutrition, dysentery, snake bites, etc. Since Thyagarajan, an Indian scholar, reported that Phyllanthus phylloxera can make 59% of hepatitis B surface antigen negative, its anti-hepatitis B virus effect has caused extensive research at home and abroad. At present, the main researches on Phyllanthus phylloxera are its anti-tumor effect and anti-hepatitis B virus effect. [0003] Recently, it has been found that Phyllostachys phy...
