Description

Technical Field

[0001] This invention relates to the field of natural plant extraction technology, specifically to a compound plant extract and its preparation method. Background Technology

[0002] In existing plant extraction technologies, distillation can only extract volatile components and cannot effectively obtain water-soluble or heat-sensitive non-volatile components; while decoction / boiling methods can dissolve non-volatile components, they easily lead to the decomposition of heat-sensitive components, and volatile components are lost with the steam. These two separate processes suffer from low utilization rates of effective components, cumbersome processes, and high energy consumption. This invention addresses the shortcomings of existing technologies by providing an integrated extraction solution through component optimization and process innovation. Summary of the Invention

[0003] The present invention aims to overcome the shortcomings of the prior art and provide a compound plant extract composed of the following raw materials in parts by weight: 5-15 parts of ox tongue grass, 3-10 parts of silkworm cocoon, 4-12 parts of fragrant orchid, 4-12 parts of basil, 2-8 parts of thorn sugar, 3-10 parts of lavender, 2-6 parts of fennel, 2-6 parts of cardamom, 5-15 parts of red dates, 3-10 parts of multi-petaled rose, and 3-10 parts of gourd seeds.

[0004] Specifically, the weight ratio of the raw materials is as follows: 10 parts of ox tongue grass, 6 parts of silkworm cocoons, 8 parts of fragrant orchid, 8 parts of basil, 5 parts of sage, 6 parts of lavender, 4 parts of fennel, 4 parts of cardamom, 10 parts of red dates, 6 parts of multi-petaled rose petals, and 6 parts of gourd seeds.

[0005] Specifically, it includes the following steps: S1. Weigh each raw material according to the ratio, mix them, add 8-10 times the amount of purified water, and soak at room temperature for 1 hour. S2. Transfer the soaked material to a distillation kettle, heat it to 200°C for cooking, and simultaneously turn on the distillation and condensation system to distill and extract while cooking. Control the temperature of the distillate to ≤40°C, collect the distillate, and after cooling, obtain a uniform, milky, light yellow, clear liquid with no obvious oil-water separation. S3. Continue simmering for 1-3 hours, then filter the remaining liquid in the pot to obtain a non-volatile extract. S4. Mix the pale yellow clear liquid obtained in step S2 with the extract obtained in step S3 until homogeneous to obtain the compound plant extract.

[0006] Specifically, the heating method described in step S2 is electric heating.

[0007] Specifically, step S4 includes concentration and drying steps to produce an extract, powder, or liquid formulation.

[0008] Specifically, the compound plant extracts are used in the preparation of daily chemical products, pharmaceutical products, health foods, or plant-based beverages with anti-inflammatory, soothing, antioxidant, body-mind-regulating, and sleep-aiding effects.

[0009] The beneficial effects of this invention are as follows: The compound extract of this invention has a high retention rate of volatile components and an essential oil yield that is more than 20% higher; the non-volatile active components are fully extracted, and the total flavonoid and polyphenol content is significantly increased; the process steps are simplified, and energy consumption is reduced by more than 30%; the resulting extract has multiple effects including anti-inflammatory, antioxidant, soothing, conditioning the mind and body, and sleep aid.

[0010] The above description is merely an overview of the technical solution of the present invention.
