Jiuquan City, situated at the westernmost end of the Hexi Corridor in Gansu Province, benefits from abundant sunshine, an arid climate, significant diurnal temperature variations, favorable irrigation conditions, and low winter temperatures. These environmental factors establish the region as one of the world's most optimal areas for hop cultivation. Jiuquan, Gansu, holds a pivotal position in China's hop cultivation area and production volume. In 2022, Gansu Province's hop cultivation area reached 34,000 mu (approximately 2,267 hectares), yielding 6,500 metric tons, accounting for 54% of the national market share and ranking first in China.

Hops extract comprises several classes of bioactive compounds, including:

Bitter Acids:

α-Acids: These include humulone, cohumulone, and adhumulone, and are the primary contributors to the bitter taste of beer.
β-Acids: These include lupulone, colupulone, and adlupulone, which also contribute to bitterness and exhibit antimicrobial activity.
Flavonoids:

Xanthohumol: A significant component of hops extract, xanthohumol exhibits diverse biological activities, including antioxidant, anti-inflammatory, and potential anticancer properties.
Isoxanthohumol: An isomer of xanthohumol, displaying similar biological activities.
Other Flavonoids: Such as 8-prenylnaringenin (8-PN).
Volatile Components:

Volatile Oils: Constituting approximately 0.5% to 2.0% of the dry weight of hops, these oils encompass over 200 compounds, including myrcene, humulene, and caryophyllene, contributing the characteristic aroma of hops.
Other Constituents:

Polyphenols: Such as quercetin glycosides and rutin, known for their antioxidant properties.
Resins: Including derivatives of α-acids and β-acids, which possess antimicrobial and preservative effects.
Amino Acids and Pectin: Hops also contain a variety of amino acids and pectin.

The diverse array of active components and available specifications of hops extract allows for the selection of appropriate extraction processes and product grades tailored to specific application requirements.

The production process of hops extract via organic solvent extraction primarily involves the following steps:

1. Raw Material Preparation:

Raw Material Selection: High-quality female hop cones (Humulus lupulus L.) are selected as the raw material. These typically undergo drying and milling to a suitable particle size to facilitate subsequent extraction.
Solvent Selection: Appropriate organic solvents are chosen based on the polarity of the target compounds. Common solvents include ethanol, acetone, ethyl acetate, and petroleum ether.

2. Extraction Process:

Solvent Maceration/Extraction: The milled hops are immersed in a specific volume of organic solvent, often employing heat reflux extraction. For instance, flavonoid extraction can be effectively achieved using 70% ethanol as the solvent under reflux for three 2-hour cycles.
Ultrasound-Assisted Extraction: In certain processes, ultrasound-assisted extraction may be utilized to enhance extraction efficiency. For example, a mixture of 60% ethanol and water at 60°C with ultrasound treatment for 30 minutes can yield higher xanthohumol content.
Sequential Solvent Extraction (Multi-Polarity): For the extraction of complex mixtures of compounds, sequential extraction with solvents of varying polarities can be employed. For example, petroleum ether can be used initially to extract lipophilic components (such as alpha-acids and beta-acids), followed by ethyl acetate or n-butanol to extract more polar compounds (like flavonoids and polyphenols).

3. Filtration and Concentration:

Filtration: Following extraction, the resulting liquid is filtered to remove solid residues, yielding a clarified extract solution.
Concentration: The filtered extract solution is then subjected to vacuum concentration to remove the solvent, resulting in a concentrated extract. This process is typically conducted at 80°C under a reduced pressure of -0.1 MPa.

4. Purification and Enrichment:

Resin Adsorption: Macroporous resins are used for adsorption and purification of the extract, further increasing the concentration of target compounds. For example, D101 macroporous resin can be used to adsorb flavonoids, followed by elution with a 75% ethanol solution.
Gradient Elution: For complex extracts, gradient elution can be employed to progressively separate components with different polarities.

5. Drying, testing and Packaging:

Drying: The concentrated extract is dried to obtain the final hops extract in powder or liquid form. Common drying methods include the spray drying method.
Packaging: The dried extract is packaged and hermetically sealed, and stored in a cool, dry place, away from direct sunlight and moisture.
