Zhejiang Anji Bai Cha (Camellia sinensis 'Anji Bai Cha')

Anji Bai Cha is a rare albino white tea cultivar from Zhejiang Province containing exceptionally high theanine levels and unique polysaccharides. Its polysaccharide extracts demonstrate antioxidant properties through free radical scavenging mechanisms.

Origin & History

Zhejiang Anji Bai Cha is a rare albino green tea cultivar from Anji County, Zhejiang Province, China, distinguished by young shoots that turn white under low-temperature conditions before reverting to green. Derived from Camellia sinensis, it contains exceptionally high levels of amino acids, catechins, and carbohydrates in its young shoots.

Historical & Cultural Context

Anji Bai Cha is a modern Chinese tea cultivar prized for its unique albino shoots and flavor, with no documented historical use in traditional medicine systems identified. While general Camellia sinensis has recognized pharmacological properties in traditional use, this specific variant lacks traditional medicinal documentation.

Health Benefits

• Antioxidant activity: Polysaccharide extracts demonstrate free radical scavenging properties (preliminary in-vitro evidence)
• Potential cholesterol management: Related albino tea flowers show anti-cholesterol activity in laboratory studies (preliminary evidence)
• Amino acid supplementation: Contains high levels of theanine, proline, and γ-aminobutyric acid in comparable cultivars (compositional analysis only)
• Polyphenol content: Rich in catechins and flavonols that may support cellular health (no human studies available)
• Traditional tea benefits: As a Camellia sinensis variant, may share general green tea properties (no cultivar-specific human evidence)

How It Works

Anji Bai Cha's polysaccharide compounds exhibit antioxidant activity by scavenging DPPH and hydroxyl free radicals. The tea's elevated L-theanine content may modulate GABA neurotransmitter pathways. Related albino tea flower compounds appear to influence cholesterol metabolism through HMG-CoA reductase pathway interactions.

Scientific Research

No human clinical trials, RCTs, or meta-analyses specifically on Anji Bai Cha were identified. General Camellia sinensis studies exist (PMID: 17899383 for green tea infusion composition), but none target this specific cultivar. Current evidence is limited to in-vitro antioxidant studies and compositional analyses.

Clinical Summary

Current evidence is limited to preliminary in-vitro studies examining polysaccharide extracts' free radical scavenging capacity. Laboratory studies on related albino tea flowers suggest potential anti-cholesterol activity, though specific mechanisms require clarification. No human clinical trials have been conducted on Anji Bai Cha specifically. The evidence base remains in early developmental stages requiring controlled human studies.

Nutritional Profile

Anji Bai Cha is consumed primarily as a brewed tea infusion, so nutritional impact reflects water-soluble compounds extracted during steeping. Bioactive compounds are the primary nutritional focus: Theanine (L-theanine) is exceptionally high at approximately 5–8% of dry leaf weight during the albino growth phase (spring flush), significantly exceeding standard green tea cultivars (typically 1–2%); theanine bioavailability from tea infusion is estimated at 80–90%. Total free amino acids reach 4–10% of dry weight during the white-leaf phase, including elevated proline, glutamic acid, aspartic acid, and γ-aminobutyric acid (GABA, approximately 0.2–0.5 mg/g dry leaf). Polyphenols are paradoxically low during the albino phase due to chlorophyll-related enzyme suppression: total catechins approximately 8–12% dry weight (versus 15–25% in standard green teas), with EGCG (epigallocatechin gallate) at roughly 3–6% dry weight, contributing reduced astringency. Chlorophyll content is markedly low during albino phase (<0.1 mg/g dry leaf) but recovers in later growth stages. Caffeine content is moderate at approximately 2–4% dry weight. Minerals in brewed infusion include manganese (0.3–0.5 mg/100 ml), potassium (20–40 mg/100 ml), and fluoride (0.1–0.3 mg/100 ml). Vitamin C is present in fresh leaf but largely degraded during processing; trace B vitamins including riboflavin and niacin are present at <0.1 mg/100 ml in infusion. Polysaccharides (0.5–2% dry weight) contribute antioxidant activity. Fiber and fat are negligible in brewed form. The high theanine-to-catechin ratio is the defining nutritional characteristic of this cultivar.

Preparation & Dosage

No clinically studied dosage ranges are available for Anji Bai Cha due to lack of human trials. General green tea preparation methods apply, with polysaccharides typically extracted via optimized hot water methods. Consult a healthcare provider before starting any new supplement.

Synergy & Pairings

L-theanine, EGCG, Vitamin C, Quercetin, Green tea extract

Safety & Interactions

As a tea cultivar, Anji Bai Cha is generally considered safe when consumed in typical beverage amounts. The caffeine content may interact with stimulant medications and should be limited in individuals sensitive to caffeine. High theanine levels are typically well-tolerated but effects during pregnancy remain unstudied. Individuals on anticoagulant medications should monitor intake due to potential polyphenol interactions.
