CO2 Extraction Method for Full-Spectrum Cannabis Oil

As consumers become increasingly educated about cannabis products, there’s a growing demand for full-spectrum cannabis oils — those that retain the full range of cannabinoids, terpenes, flavonoids, and other beneficial compounds from the original plant.

To meet this demand, producers must use an extraction method that is selective, efficient, and clean. That’s where the co2 supercritical extraction machine from Shanghai North Brooks Co.,ltd. comes in — delivering pharmaceutical-grade full-spectrum extracts through a fully tunable and solvent-free process.

1. What Is Full-Spectrum Cannabis Oil?

Full-spectrum oil includes:

• Major cannabinoids like THC and CBD

• Minor cannabinoids like CBG, CBC, CBN

• Terpenes that influence aroma, flavor, and the entourage effect

• Flavonoids and phenolics for added wellness impact

Unlike isolates, full-spectrum products offer synergistic therapeutic effects, and must therefore preserve even the most delicate components of the cannabis plant.

2. Why CO2 Supercritical Extraction?

CO2 extraction is ideal for full-spectrum preservation because it:

• Operates at low temperatures to avoid thermal degradation

• Offers tunable selectivity for target compound profiles

• Uses no chemical solvents, making it safe and clean

• Enables multi-stage fractionation to separate undesired components (like wax or chlorophyll)

A high-quality co2 supercritical extraction machine provides unmatched control, allowing operators to extract a true full-spectrum profile — batch after batch.

3. North Brooks' Full-Spectrum CO2 Extraction Solution

Shanghai North Brooks Co.,ltd. has engineered a fully modular system designed for maximum cannabinoid and terpene retention.

“We’ve worked with ethanol and hydrocarbon extraction before — but the co2 supercritical extraction machine from North Brooks was the first that gave us real full-spectrum consistency. No solvent taste, no filtration nightmare.”
— Director of Production, Brightfield Wellness

5. The Entourage Effect and Fractional Extraction

The entourage effect refers to the synergistic interaction between cannabinoids and terpenes. North Brooks’ systems enable operators to:

• Set fractional separation temperatures

• Tailor cannabinoid + terpene outputs

• Remove waxes or lipids without losing essential actives

Operators can now control and replicate the full-spectrum fingerprint unique to each strain.

6. Clean, Compliant, and Certified

• GMP, CE, and ISO certified

• CO2 fully recycled and captured in a closed-loop

• No flammable solvents

• Suitable for medical cannabis and nutraceutical production

North Brooks provides full documentation and support for global compliance needs.

Conclusion

Producing high-value full-spectrum cannabis oil isn’t about luck — it’s about precision. With the co2 supercritical extraction machine from Shanghai North Brooks Co.,ltd., producers gain the tools to deliver clean, potent, terpene-rich oils that meet market demands and regulatory standards.

Whether you’re building a craft cannabis brand or supplying to pharmaceutical buyers, this is the gold standard of extraction.
