This invention discloses a compound preparation for treating vascular dementia and its preparation method. The active pharmaceutical ingredient consists of protopanaxadiol and gallic acid in a 1:1 mass ratio, and the dosage form is liposomes. The preparation method includes extraction, mixing, liposome preparation, and optional freeze-drying steps: protopanaxadiol and gallic acid are extracted and purified from ginseng rhizome and Terminalia chebula fruit, respectively. After mixing, they are combined with phospholipids and cholesterol to prepare a lipid membrane. The membrane is then homogenized by hydration, low-temperature ultrasound, and high-pressure microfluidic jet to obtain a homogeneous liposome suspension, which can be further freeze-dried into a freeze-dried powder. The 1:1 composition of protopanaxadiol and gallic acid targets multiple points on the pathological mechanism of vascular dementia, showing significant therapeutic effects and broad application prospects. This preparation uses a liposome dosage form to improve the bioavailability of the active ingredient, the preparation process parameters are controllable, the active ingredient has high purity, the liposomes have uniform particle size, high encapsulation efficiency, and good stability.

The invention relates to the technical field of traditional Chinese medicine, in particular to a traditional Chinese medicine composition suitable for type II diabetes and a preparation method and application thereof. The traditional Chinese medicine composition is prepared from the following raw materials in parts by weight: 30 to 45 parts of radix astragali seu hedysari, 20 to 30 parts of herba dendrobii, 30 to 45 parts of rhizoma polygonati, 20 to 30 parts of radix ophiopogonis and 20 to 30 parts of corn stigma. According to the traditional Chinese medicine composition, through the synergistic effect of core components such as astragalus membranaceus for tonifying qi, lifting yang, promoting salivation and nourishing blood, dendrobium nobile for tonifying stomach and promoting salivation, polygonatum kingianum for tonifying qi, nourishing yin, moistening lung and tonifying kidney, radix ophiopogonis for nourishing yin and promoting salivation and the like, glucose metabolism balance is effectively adjusted, insulin resistance is improved, and therefore the effect of reducing blood glucose and / or lipid is achieved.

This invention relates to the field of traditional Chinese medicine preparation technology, specifically to a Qi-invigorating and blood-activating granule for heart pain and its preparation method, comprising the following raw materials in parts by weight: 25-35 parts of raw Astragalus membranaceus, 10-20 parts of Angelica sinensis, 5-15 parts of ginseng, 4-8 parts of Panax notoginseng, 10-20 parts of Ligusticum chuanxiong, 8-12 parts of earthworm, and 2-4 parts of leech. This invention precisely targets the core pathogenesis of Qi deficiency and blood stasis syndrome, which is "Qi deficiency as the root and blood stasis as the manifestation," selecting raw Astragalus membranaceus and ginseng as the core Qi-invigorating components, and Panax notoginseng, leech, Ligusticum chuanxiong, Angelica sinensis, and earthworm as the core blood-activating components. The formulation follows the traditional Chinese medicine principle of "invigorating Qi to promote blood circulation without harming the body's vital energy." The dosage of each raw material has been optimized through systematic experiments to form a specific range of parts by weight, solving the technical problems of poor targeting and insufficient synergy in existing formulations.
