## 中文原料产地｜Raw Material Origin (CN)

产品：(-)-表没食子儿茶素没食子酸酯 / (-)-Epigallocatechin-3-O-gallate（EGCG，C₂₂H₁₈O₁₁，CAS 989-51-5，山茶科茶 *Camellia sinensis* (L.) O. Kuntze 未发酵嫩叶黄烷-3-醇没食子酸酯）

供应商：长沙上禾生物科技有限公司（Changsha Staherb Natural Ingredients Co., Ltd. / Staherb®，2010 年长沙麓谷，环创 B8 202，国家高新技术企业）

植物基源与种源：茶原生中国西南（云贵川）、栽培主中心华东/华南，EGCG 富集于春茶一芽二叶嫩梢（老叶/梗茎骤降、夏秋茶略低、发酵茶近无）；以中小叶种 *C. sinensis* var. *sinensis*（龙井 43、乌牛早、福鼎大白、径山绿）为主供，部分高标 EGCG 批调剂用大叶种 *var. assamica*（云南普洱/临沧/西双版纳）；拒绝红茶/乌龙/普洱等发酵茶投料（PPO 未钝化→儿茶素聚为茶黄/茶红素，EGCG 崩解）。同株伴生 EGC/ECG/EC、咖啡因、L-茶氨酸、没食子酸——EGCG 是 HPLC 274 nm 首要 Marker，不混迷迭香酸式水溶酚酸。

Staherb 产地策略（"浙江早春主轴 + 皖南辅供 + 云南大叶特批 + 闽湘川鄂赣苏滚动补入"多源定点）

Staherb 采用"公司+茶园/初制厂+备案"订单农业：在中国绿茶核心产区建定点备案/部分有机无公害基地收春绿毛茶→晴天上午采、4–6 h 内杀青（锅炒 230–280℃ 数十秒至 2 min 或蒸青 100℃ 30–60 s 钝化 PPO）→揉捻→烘干水分≤7%→密封运长沙，麓谷 B8 仅做低温水/醇提→大孔树脂→脱咖/茶氨酸分流→制备 HPLC/重结晶→标化分装，非种植产地（COA 注 "Origin: China / Processed in Changsha, Hunan"）。多源策略规避单产区气候波动，保工业批 EGCG 基线稳（投料优选总儿茶素≥22%–28%、EGCG≥11%–16% DW）。

核心产区与投料特点

• 主供主轴｜浙江·杭州西湖周边（龙井）、丽水（径山/乌牛早）、温州：中小叶种酚氨比适中，春茶一芽二叶总儿茶素 22%–28% DW、EGCG 11%–16% DW，杀青工艺成熟，龙井 43/乌牛早为优选栽培种，部分茶园有机/无公害认证；Staherb ≥50% 投料批首选前体，TP 50%–98% / EGCG 40%–98% 批主线。

- 重要辅供｜安徽·黄山（毛峰）/宣城/六安（瓜片）：皖南及大别山微气候，水浸出物高（GB/T 14456 ≥36%），黄山毛峰/太平猴魁绿芽 TP 稳 20%–25%，作主要补充与年份高含量调剂。

- 高 EGCG 特批/成本调剂｜云南·普洱（思茅）/临沧/西双版纳：大叶种 *var. assamica* 干茶 EGCG 12%–16%+ 绝对量高，但伴生 EGC 比略异、涩感偏重、咖啡因伴生略高；仅用于特定高标 EGCG 单体批或成本调剂，入厂严控苦涩/杂质。

- 滚动补入｜福建（福鼎/政和烘青）、湖南（古丈/安化烘青）、四川（峨眉/蒙顶）、湖北（恩施玉露蒸青）、江西（婺源/庐山）、江苏（洞庭/宜兴）：按年份气候与含量波动补入，恩施玉露遮荫蒸青作高茶氨酸选批（L-Theanine≥1.5% DW）。

- 进口定制｜日本蒸青（玉露/煎茶粉副产）：仅高标研究批极小量调剂，不工业主源。

• 拒收红线：非 *C. sinensis*（冬青/钩藤/蒲桃叶等形态 TLC 鉴）、红茶/乌龙/普洱等发酵茶（EGCG 已氧化）、夏秋老叶（EGCG<9% DW）、陈茶（存>2 年光氧化褐变）、霉变、硫熏（SO₂>150 mg/kg）、农残超（茶系吸药作物严检六六六/DDT/吡虫啉/菊酯/草甘膦）、Pb>1 ppm（茶限量）/Cu>10 ppm、总儿茶素初值<18% 或 EGCG<9% DW。

采收与初制窗口

• 春茶（3 月中–4 月底）晴天上午采一芽二叶初展→ 摊青 2–4 h → 杀青（锅炒 230–280℃ 数十秒–2 min 或蒸青 100℃ 30–60 s，钝化 PPO 防儿茶素红变）→ 揉捻 → 烘干/半烘半炒至水分≤7%；遮荫栽培（遮光 50%–70% 2–3 周）L-Theanine 升至 1.5%–3.0% DW 作高茶氨酸选批。

- 初制厂双麻袋内衬 PE 密封干处贮（忌湿热霉变、忌与硫磺/花茶共库），每批附基原（*C. sinensis* var. *sinensis*/assamica）+ 产区（到县）+ 采期（到旬）+ 杀青方式 + 初水分 + 初总儿茶素（HPLC 278 nm）+ 初 EGCG（HPLC 274 nm）+ 初咖啡因 + 农残批号 + 茶园/初制厂备案号。

- Staherb 入厂拒收：陈货（存>2 年光氧化）、硫熏、发酵茶未声明、冬青/桉混杂（形态+TLC 鉴）、EGCG 干茶<9% DW。

入厂基线（Staherb 快检红线）

## English Raw Material Origin｜EN

Product: (-)-Epigallocatechin-3-O-gallate / EGCG (C₂₂H₁₈O₁₁, CAS 989-51-5, flavan-3-ol gallate from Theaceae *Camellia sinensis* (L.) O. Kuntze unfermented young leaf)

Supplier: Changsha Staherb Natural Ingredients Co., Ltd. (Staherb®, Changsha Lugu B8-202, since 2010)

Botanical source & germplasm: Tea native SW China (Yunnan-Guizhou-Sichuan), cultivation center E/S China; EGCG enriches in spring 1-bud-2-leaf tender shoot (old leaf/stem plunge, summer-autumn slightly lower, fermented tea near-zero); main feed small-medium leaf *C. sinensis* var. *sinensis* (Longjing 43, Wuniuzao, Fuding Dabai, Jingshan), high-grade batch adjusts with large-leaf *var. assamica* (Yunnan Puer/Lincang/Xishuangbanna); rejects black/oolong/pu-erh fermented tea (PPO not denatured → catechins polymerize to theaflavin/thearubigin, EGCG collapsed). Companions EGC/ECG/EC, caffeine, L-theanine, gallic acid — EGCG is HPLC 274nm primary marker, not rosmarinic-type water-soluble acid.

Staherb origin strategy ("Zhejiang early-spring primary + Anhui-S Anhui co-feed + Yunnan large-leaf high-EGCG special + Fujian/Hunan/Sichuan/Hubei/Jiangxi/Jiangsu roll-adjust" multi-source registered)

Staherb runs "company+tea-garden/primary-plant+registry" order-farming: fixed registered / partial organic-pollution-free bases in CN green-tea core belts → harvest sunny AM, fix within 4–6 h (pan 230–280℃ seconds–2min or steam 100℃ 30–60s denature PPO) → roll → dry moisture≤7% → sealed to Changsha, Lugu B8 only does low-temp water/EtOH extract → macroporous → decaf/theanine split → prep-HPLC/recryst → standardize-repack, NOT plantation (COA "Origin: China / Processed in Changsha, Hunan"). Multi-source avoids single-region climate swing, keeps industrial EGCG baseline steady (feed pref total catechins≥22–28%, EGCG≥11–16% DW).

Core regions & feed traits

• Primary spine｜Zhejiang·Hangzhou-Xihu/Lishui(Jingshan/Wuniuzao)/Wenzhou: small-medium leaf phenol/amino balanced, spring 1-bud-2-leaf total catechins 22–28% DW, EGCG 11–16% DW, fixation mature, Longjing 43/Wuniuzao preferred cultivars, partial organic/pollution-free; Staherb ≥50% feed batch first-choice precursor, TP 50–98% / EGCG 40–98% main line.

- Important co-feed｜Anhui·Huangshan(Maofeng)/Xuancheng/Luan(Guapian): S-Anhui & Dabie microclimate, water-extract high (GB/T 14456 ≥36%), Huangshan Maofeng/Taiping Houkui green TP steady 20–25%, main replenish & year-high-content adjust.

- High-EGCG special/cost-adjust｜Yunnan·Puer(Simao)/Lincang/Xishuangbanna: large-leaf *var. assamica* dry-tea EGCG 12–16%+ absolute high, but companion EGC ratio slightly off, astringency heavier, caffeine companion slightly higher; only specific high-EGCG monomer batch or cost-adjust, inbound strict astringency/impurity control.

- Roll-adjust｜Fujian(Fuding/Zhenghe green), Hunan(Guzhang/Anhua roast-green), Sichuan(Emei/Mengding), Hubei(Enshi Yulu steam-green), Jiangxi(Wuyuan/Lushan), Jiangsu(Dongting/Yixing): year/climate fluctuation fill-in; Enshi Yulu shade-cultivar for high-theanine select batch (L-Theanine≥1.5% DW).

- Import custom｜Japanese steam-green (Gyokuro/Sencha powder by-product): only high-std research batch minimal adjust, not industrial main.

- Reject gates: non-*C. sinensis* (holly/uncaria/myrtaceous TLC), fermented tea (EGCG oxidized), summer-autumn old-leaf (EGCG<9% DW), aged>2yr photo-oxidized, mold, SO₂-bleach(>150mg/kg), pesticide over (tea crop tight BHC/DDT/imidacloprid/pyrethroid/glyphosate), Pb>1ppm (tea strict)/Cu>10ppm, total catechins<18% or EGCG<9% DW.

Harvest & primary-process

• Spring (mid-Mar–end-Apr) sunny AM 1-bud-2-leaf → wither 2–4h → fix (pan 230–280℃ seconds–2min or steam 100℃ 30–60s, denature PPO prevent catechin red-shift) → roll → dry/semi-roast moisture≤7%; shade-cultivar (50–70% shade 2–3wk) L-Theanine↑1.5–3.0% DW for high-theanine select.

- Primary-plant double-burlap PE-sealed cool-dry (no wet-heat mold, no co-store sulfur/scented-tea), each lot with basorigin (var. sinensis/assamica) + county-origin + harvest(10-day) + fixation mode + initial moisture + initial total-catechins (HPLC 278nm) + initial EGCG (HPLC 274nm) + initial caffeine + pesticide lot + garden/primary-reg.

- Staherb rejects aged>2yr (photo-oxidize), SO₂-bleached, fermented undeclared, holly/eucalyptus admix (morph+TLC), dry-tea EGCG<9% DW.

Inbound baseline (Staherb quick-test redline)

• Green maocha: moisture≤7%, total-ash≤6.5%, water-extract≥36% (GB/T 14456), SO₂≤150 mg/kg;

- Total catechins (HPLC-UV@278nm 4-peak) ≥22–28% DW (pref), EGCG (HPLC 274nm, EGCG CRS ext) 11–16% DW (pref≥11%, reject<9%);

- Caffeine 3–6% DW (assamica slightly high), L-Theanine 1.0–2.5% DW (shade-select≥1.5%);

• Heavy: Pb≤1 ppm (tea strict), Cu≤10 ppm, Cd≤0.3 ppm;

- Pesticide: GB 2763 + EU 396/2005 + Japan pos-list (tea tight organochlorine/organophosphorus/pyrethroid/pyrrole);

- Sensory: tender green leaf-base, chestnut/seaweed note, no red-stem/red-leaf, no stale.
