I. Botanical Characteristics and Raw Material Sources of Yucca
Yucca schidigera is a perennial evergreen shrub in the Liliaceae family, native to North American arid deserts, thriving in high temperatures (>40°C) and low rainfall (<200mm annually). It grows 1-3 meters tall with sword-shaped leaves and white flowers. Its rhizomes are rich in active ingredients for extract production. Due to scarce wild resources, cultivation is primary in California, Arizona, and Mexico’s Baja California Peninsula, with over 100,000 hectares cultivated and high rhizome yields.
II. Core Components: Molecular Structure and Mechanism of Action
Yucca extract contains steroidal saponins (40%-60%), polyphenols (15%-25%), polysaccharides (10%-20%), and minor alkaloids, amino acids, and minerals.
1. Steroidal Saponins: Core for surface activity and gas binding. Yucca saponin A has strong surface activity; saponin B binds ammonia effectively. Mechanism: Reduce water surface tension, enhancing nutrient absorption; bind ammonia and hydrogen sulfide via hydrogen bonding.
2. Polyphenols: Natural antioxidants and anti-inflammatories, including resveratrol, chlorogenic acid, quercetin, and caffeic acid. Mechanism: Scavenge free radicals with high ORAC values; anti-inflammation via inhibiting COX-2 and LOX, and downregulating NF-κB.
3. Polysaccharides: Heteropolysaccharides composed of glucose, galactose, arabinose, and rhamnose, with molecular weight 10-100 kDa (20-50 kDa most active). Mechanism: Activate mucosal immunity by binding TLR4 and increasing sIgA; regulate flora balance by promoting beneficial bacteria and inhibiting harmful baceria.
| Core Component | Content Range | Key Subtypes/Composition | Core Functions |
| Steroidal Saponins | 40%-60% | Yucca saponin A, B, C (spirostanol skeleton + 1-3 sugar chains) | Reduce surface tension, bind harmful gases, synergistic dispersion of other components |
| Polyphenols | 15%-25% | Resveratrol (30% of total), chlorogenic acid, quercetin, caffeic acid | Antioxidation (high ORAC value), anti-inflammation (inhibit inflammatory mediators) |
| Polysaccharides | 10%-20% | Glucose (60%), galactose (25%), arabinose (10%), rhamnose (5%) | Activate mucosal immunity, regulate intestinal flora balance |
III. Application Fields: Full-Scale Expansion Across Industries
1. Livestock and Poultry Breeding: Yucca extract is a natural additive replacing antibiotics, used in pigs, chickens, cattle, and sheep for environmental improvement and antibiotic-free breeding.
(1) Improving Breeding Environment: Precisely Reducing Harmful Gas Concentrations
| Breeding Type | Addition Dosage | Ammonia Concentration Change | Hydrogen Sulfide Concentration Change | Incidence/Mortality Change |
| Finishing Pigs | 0.2% | 18mg/m³ → 8mg/m³ (55.6% decrease) | 3.2mg/m³ → 1.1mg/m³ (65.6% decrease) | Respiratory disease incidence: 12% → 3% (75% reduction) |
| Layers | 0.15% | Stabilized at 5-7mg/m³ (national standard ≤15mg/m³) | – | Mortality rate: 4% → 1.5% (62.5% reduction) |
Mechanism analysis: The binding of saponins to ammonia is dose-dependent (higher addition leads to higher binding rate) and pH-dependent (binding rate reaches over 90% at intestinal pH 6.5-7.0).
(2) Promoting Nutrient Absorption: Enhancing Production Performance
| Breeding Type | Addition Dosage | Key Production Performance Indicators |
| Broilers | 0.2% | Feed conversion ratio (FCR): 1.85 → 1.62 (12.4% improvement); Average daily gain (ADG): 52g → 58g (11.5% increase); Intestinal villus height +30%, crypt depth -25% |

(3) Replacing Antibiotics: Core Solution for Antibiotic-Free Breeding
EU case: A Dutch farm used yucca extract to replace antibiotics (e.g., oxytetracycline) in 2021. Pig survival rate increased from 92% to 96% (4% increase), feed costs decreased by 8%, and pork drug residues (e.g., oxytetracycline) dropped from 0.12mg/kg to undetectable levels (complying with EU standards).
Chinese case: A Shandong broiler farm adopted a compound additive of “yucca extract + probiotics” in 2022, reducing antibiotic use by 70%. Broiler survival rate increased from 93% to 97% (4% increase), and the qualification rate of products exported to Japan reached 100%.
Scientific basis: The multi-targeted effects of yucca extract (inhibiting harmful bacteria, enhancing immunity, improving the environment) can replace the “single bactericidal” effect of antibiotics without the risk of drug resistance (2023 review in Veterinary Pharmacology and Therapeutics).

The production process of yucca extract directly impacts the retention rate and purity of active ingredients. Current mainstream processes include water extraction-alcohol precipitation, ultrasonic-assisted extraction, and supercritical CO₂ extraction. Their characteristics are compared below:
| Extraction Process | Process Flow | Purity | Extraction Rate | Advantages | Disadvantages |
| Water Extraction-Alcohol Precipitation (Traditional) | Dried rhizomes → crushing (20-40 mesh) → water extraction (80℃, 2h, solid-liquid ratio 1:10) → filtration → alcohol precipitation (70% ethanol, 4℃, 12h) → centrifugation → spray drying (150℃) → finished product | 80%-85% | 30%-40% | Low cost, simple equipment, suitable for large-scale production | Time-consuming (>12h), low extraction rate, polysaccharide degradation (high-temperature-induced glycosidic bond breakage) |
| Ultrasonic-Assisted Extraction (Modern) | Dried rhizomes → crushing (40-60 mesh) → ultrasonic extraction (200W, 60℃, 30min, solid-liquid ratio 1:15) → filtration → alcohol precipitation → centrifugation → drying → finished product | 85%-90% | 50%-60% | High extraction rate, short time (75% reduction), high polysaccharide retention rate (>90%) | High equipment cost (2-3× traditional), high energy consumption (200W/hour) |
| Supercritical CO₂ Extraction (High-End) | Dried rhizomes → crushing (60-80 mesh) → supercritical CO₂ extraction (30MPa, 40℃, 2h, entrainer: ethanol) → separation → drying → finished product | 90%-95% | – | High purity (active ingredient retention >95%), no solvent residue, suitable for heat-sensitive components (e.g., polyphenols) | Extremely high cost (10× traditional), low output (suitable for small-batch high-end products) |
Process Optimization Directions
Composite process: Combining “ultrasonic-assisted extraction + supercritical CO₂ extraction” balances extraction rate (60%) and purity (90%), shortening the time to less than 2 hours (2023 study in Separation and Purification Technology).
Enzyme-assisted extraction: Adding cellulase (0.5%) and pectinase (0.3%) during water extraction breaks down plant cell walls (cellulose and pectin), increasing the extraction rate by 20%-30% (2022 study in Science and Technology of Food Industry).
