Description

Lucid ganoderma and dendrobium officinale suspension and preparation method thereof
Technical Field
The invention belongs to the fields of natural product extraction and separation, health-care food and preparation, and particularly relates to a ganoderma and dendrobium officinale suspension and a preparation method thereof.
Background
Ganoderma lucidum (Ganoderma lucidum (L eyss. ex Fr.) Karst.) is one of Ganoderma lucidum (one part of Chinese pharmacopoeia 2015 edition) belonging to Polyporaceae, has sweet taste, and can strengthen body resistance and consolidate constitution, the main active ingredients are Ganoderma lucidum triterpene and Ganoderma lucidum polysaccharide, the Ganoderma lucidum triterpene has various pharmacological effects of antioxidation, immunity regulation, antitumor, liver protection, blood sugar reduction, bacteriostasis, etc., the content of Ganoderma lucidum triterpene in Ganoderma lucidum fruiting body is very low, about 0.5-1% of the weight of dried fruiting body, and is insoluble in water, and can be made into capsule, tablet and powder, after being taken, the Ganoderma lucidum triterpene is difficult to dissolve and absorb in digestive tract, and has low bioavailability, and in addition, part of Ganoderma lucidum triterpene has long taste bud retention time and poor taste, and affects the compliance of users.
The Dendrobium officinale is dry stem of Dendrobium officinale (Dendrobium officinale Kimum et Migo) of Orchidaceae, is sweet and slightly cold in taste, can benefit stomach and promote fluid production, contains Dendrobium officinale polysaccharide as main active ingredient, and has various pharmacological effects of resisting oxidation, regulating immunity, resisting tumor, reducing blood sugar, promoting digestion, etc. The content of the dendrobium officinale polysaccharide in the dendrobium officinale is more than 25%, meanwhile, the dendrobium officinale polysaccharide also contains a large amount of substances such as pectin and the like, the dendrobium officinale water extract is sticky and difficult to filter and dry into powder, and in addition, the three-dimensional structure of the dendrobium officinale polysaccharide is easy to inactivate in a high-temperature environment, so that the pharmacological activity of the dendrobium officinale polysaccharide is influenced.
The invention discloses a dendrobium candidum ganoderma lucidum capsule (CN 102772313.9). the dendrobium candidum ganoderma lucidum capsule is prepared by firstly crushing a dendrobium candidum raw material by a supersonic airflow crusher to obtain dendrobium candidum super-particles with the particle size of 1-75 mu m; meanwhile, the ganoderma lucidum raw material super-particles are crushed to obtain the ganoderma lucidum super-particles with the particle size of less than 2 mu m. Mixing the Dendrobium officinale super-particles and the lucid ganoderma super-particles, and directly filling the capsules in the form of crude drug powder to obtain the capsule. Because the content of the active ingredients in the crude drug is low, for example, the active ingredient ganoderma triterpene of ganoderma lucidum has extremely low content in the ganoderma lucidum raw material; due to the limitation of the filling amount of the capsule (0.1-1.0 g), the daily dose is often difficult to reach the lower limit of 6g in Chinese pharmacopoeia, and the pharmacological action is influenced.
The patent discloses a microwave vacuum freeze-drying method of dendrobium candidum and lucid ganoderma superfine powder (CN109594974A), the dendrobium candidum and lucid ganoderma superfine powder only extracts water-soluble components of lucid ganoderma and dendrobium candidum, only contains polysaccharide and does not contain triterpene. However, the microwave in the microwave drying means can affect the spatial structure of the polysaccharide like high temperature, so that the ganoderan and the dendrobium officinale polysaccharide are easily inactivated, and the pharmacological action is affected.
The glossy ganoderma and the dendrobium officinale have more than thousand years of medicinal history in China, are listed as the first and the second of eight immortals and grasses, and are praised as 'life saving grasses' by the nation. The two have main medicinal characteristic components, and if the two are strongly combined to prepare a suspension, the medicinal components of the suspension have synergistic action to further enhance the medicinal effect. At present, as a pharmaceutical dosage form, a suspension is usually prepared by dispersing a poorly soluble solid raw material drug in a liquid medium with the aid of an auxiliary material to prepare a suspension for oral administration. The suspension has the advantages of good dispersion degree, quick effect, high bioavailability, easy administration for dysphagia patients, etc.

Experimental test example 2
The current evaluation methods for bitterness mainly include in vivo and in vitro methods of class 2. The former includes population test, animal electrophysiological test, etc., and the latter can adopt release test, biochemical test, taste sensor, etc. The most common in-vivo taste evaluation method is the classic population taste evaluation method (mouth taste method for short). It is the most direct evaluation method and also the basis for evaluating in vitro and in vivo correlation in vitro methods.
Classic population taste evaluation method experimental materials: berberine hydrochloride reference, purified water, samples 1, 2, 3
The experimental method comprises the following steps:
1, determining bitterness evaluation grades and grading ranges of all levels:
TABLE 2 qualitative description, rating and quantitative Range of bitterness values (I)
Figure BDA0002463579680000071
2, preparation of positive and negative solutions:
the preparation of the positive solution comprises the steps of precisely weighing 500mg of berberine hydrochloride reference substances, placing the berberine hydrochloride reference substances in a 100m L measuring flask, adding 50m L of water, shaking for uniform dissolution, transferring the berberine hydrochloride reference substances to a 1000m L measuring flask, adding water to the scale to obtain a No. 5 solution, placing No. 5 solutions 200, 100 and 20m L in a 1000m L measuring flask, adding water to the scale to obtain the scale, marking the scale as No. 4, 3 and No. 2 solutions respectively, placing 1000m L of pure water in a l000 m L beaker to obtain the No. 1 solution, wherein the berberine hydrochloride in the No. 1, 2, 3, 4 and 5 reference solutions has the mass concentrations of 0.00, 0.01, 0.05, 0.10 and 0.50 g/L, the corresponding bitterness grades of I, II, III, IV and V, and the corresponding I values of 1.0, 2.0,3.0, 4.0 and 5.0 respectively.
The bitter taste value is determined by testing reference solutions, respectively taking 30m L reference solutions with various concentrations in a mouth-tasting paper cup, putting 20 volunteers (11 males, 9 females, age 23-51 years) in the mouth, timing for 10s, carrying out mouth rinsing action in the mouth so that the bitter taste perception area of the tongue can perceive the bitter taste of the drug, informing the bitter grade and specific bitter value of the solution, spitting out, rinsing for 5 times until no bitter taste exists in the mouth, and measuring another concentration of the reference solution after 20 min.
And (3) determination of a sample: according to the mouth taste of the volunteer, and the comparison with a reference solution, firstly, determining the bitterness grade according to the bitterness expression in the table 1, and recording the bitterness grade in a pre-designed medicine bitterness description table; then according to the relative bitterness of each liquid medicine in the same grade, a specific bitterness value is given to the sample to be tasted within the value range allowed by the bitterness value of the grade. And filled into the above-mentioned "bitter taste description table of the medicine"; rinse 5 times until no bitterness in the mouth, and measure another sample after 20 min. In addition, when the tested person tests the sample in the experiment, the method from low bitterness to high bitterness is adopted to gradually test the sample. The results are as follows:
TABLE 3 bitterness of Ganoderma lucidum and Dendrobium officinale suspension
Figure BDA0002463579680000081
The bitterness values of the samples 1, 2 and 3 are all less than 1.5, and the samples are judged to have no bitterness
