Embodiment 1

[0021] Preparation of "Curcuma oil-like" micronanocapsules by polymer emulsification and dispersion

[0022] A "cure-like oil" composed of β-elemene, curcumol and curdione in a weight ratio of 2:1:1 as the core material of the capsule, and polylactic acid or polylactic acid copolyglycolic acid as the shell of the capsule The preparation method of the micro-nanocapsule of the material is specifically described as follows:

[0023] ① Dissolve 100mg of polylactic acid and 125mg of lecithin with 15ml of acetone to form a uniform solution, then take 80mg of the above-mentioned "curecum-like oil" and dissolve it in 15ml of benzyl benzoate, then add it to the previous solution, and mix to form a uniform oil phase A1;

[0024] ② Dissolve 100mg of Dextran 70 in 1000ml of distilled water to form water phase B 1 ;

[0025] ③Under stirring, mix oil phase A 1 Slowly add dropwise to aqueous phase B 1 In, make it dispersed into a uniform emulsion W 1 ;

[0026] ④The above emulsion W ...

Abstract

The invention discloses a medical 'zedoary oil' and a manufacturing method for its micro capsule, the zedoary oil is acquired by confecting the beta-elemene, zedoary alcohol, curdione according to a fixed proportion, compared with natural zedoay oil, its effective ingredients content are high, and in virtue of the cooperation among the three, thus it has higher functions for resisting tumor, bacteria, and virusl; the producing method for mciro capsule is: because of increasing the even process, and through controlling the inner circulation in the even process, the particle size of the capsule is controllable between 50nm and 500nm, it can acquire the micro capsule with the uniform particle size, its irregularity is not more than plus and minus 5 nm.

Description

technical field [0001] The invention relates to a micronanocapsule of medicinal curcuma oil and a preparation method thereof. In particular, a medicinal "cure-like oil" composed of active components extracted from zedoary oil and having a stable component ratio is a nanocapsule with a core as the core and a preparation method thereof. Background technique [0002] Zedoary oil extracted from the rhizome of the Chinese herbal medicine Zedoary oil has a good anti-tumor effect, which has been confirmed by clinical trials and listed in the Chinese Pharmacopoeia. According to the Chinese Pharmacopoeia, the active components in turmeric oil with antitumor, antibacterial and antiviral functions are β-elemene, curcumol and curcumedione. However, due to the different origins of Zedoary, even in the same origin, due to the different growth years of Zedoary, the proportions of active components in the obtained Zedoary oil are very different, which brings ma...
