长沙上禾生物·育亨宾提取物(Yohimbine Extract)专业生产 中英文简介

一、中文简介(Professional Production — Chinese)

工艺路线总览:

上禾生物育亨宾提取物生产分两条主线:

  1. 标准化树皮提取物(Yohimbine 2%~20% HPLC,比例 4:1~20:1)——树皮前处理 → 酸醇提取 → 碱沉/酸沉除杂 → 大孔吸附树脂富集 → 喷雾干燥;


  2. 高纯育亨宾碱单体 / 盐酸育亨宾(≥98% HPLC)——标化提取物经大孔/离子交换树脂深度纯化、硅胶/ODS柱层析、酸转化成盐、有机溶剂重结晶精制。


关键生产工序:

① 原料前处理(关键控制点)

② 酸醇提取(Acid-Alcohol Extraction —— 生物碱溶出核心)

③ 除杂——碱沉/酸沉与脱脂(Impurity Removal)

④ 纯化富集——大孔吸附/离子交换树脂(Core Purification)

⑤ 浓缩与标化干燥

⑥ 高纯单体精制(Yohimbine Base ≥98% / Yohimbine HCl ≥98%)

⑦ 质控与包装

二、English Introduction (Professional Production — English)

Process Route Overview:

Staherb produces two main categories of Yohimbine Extract:

  1. Standardized Bark Extract (Yohimbine 2%~20% HPLC, Ratio 4:1~20:1) — Bark pre-treatment → Acid-alcohol extraction → Alkali/acid precipitation → Macroporous/Ion-exchange resin enrichment → Spray drying.


  2. High-purity Yohimbine Base / Yohimbine Hydrochloride (≥98% HPLC) — Standardized extract further purified via deep macroporous/IEX resin, silica/ODS column chromatography, salification (HCl), and organic solvent recrystallization.


Key Production Steps:

Step

Description

① Raw Material Pre-treatment

Source: Dried bark of Pausinystalia yohimbefrom Cameroon, Congo, Gabon (West/Central Africa), prefer 15–20 yr mature bark. Test: Yohimbine baseline ≥0.8%~1.5% DW (reject<0.5%~0.8%), moisture ≤10%, mold, heavy metals, non-Pausinystaliaadmixture, with CITES/local legal harvest docs. Debris removed → milled 20–40 mesh (too fine introduces lignin/resin clogging; too coarse poor alkaloid extraction). Yohimbine (indole-quinolizidine) is light/heat/extreme acid-base sensitive; pre-treatment/storage requires light protection, low-temp, pH control.

② Acid-Alcohol Extraction (Core Alkaloid Solubilization)

Yohimbine exists as alkaloidal salts or free weak base, poorly water-soluble but soluble in alcohols/acids. Extract with 50%–90% food-grade EtOH + 0.05–0.1 mol/L H₂SO₄/HCl (pH 3–4), 1:5–10 w/v, 70–85℃ reflux or ultrasound-assisted 2–3× (1–2h). H⁺ converts base to salt for solubilization. Combine → filter → vacuum conc. (≤60℃, N₂) to rel. dens. 1.10–1.20. Alternately supercritical CO₂ (with entrainer) for green extraction at higher cost.

③ De-impurity: Alkali/Acid PPT & Degreasing

Alkalinization: Adjust conc. to pH 8–10 with NH₄OH, Na₂CO₃ to precipitate impurities (resins, tannins, pigments) or precipitate free alkaloid for crude separation → filter.
Acid re-dissolution / Water precipitation: Precipitate redissolved in dilute acid → filter remove lignin/waxes; or concentrate diluted with water to water-precipitate polysaccharides/proteins/colloids.
Optionally petroleum ether/n-hexane degreasing to remove chlorophyll/fats.

④ Purification — Macroporous / Ion-Exchange Resin (Core)

Diluted acid soln loaded onto macroporous (AB-8, D101, LX-18, LS-300) or weak acid cation-exchange resins: water wash → 10%–50% EtOH/MeOH remove flavonoids, weak alkaloids, low-polar impurities → 70%–80% EtOH (or pH 8–10 alk. alcohol) gradient elution to collect Yohimbine & accompanying alkaloids (HPLC tracked, recovery 70%–80%).
For separating Pseudoyohimbine, α/β-Yohimbine, Corynanthine, secondary column or ODS/silica gel chromatography may be used.

⑤ Concentration & Standardized Drying

Eluate conc. under reduced pressure (≤50℃)spray-dry (inlet 150–160℃, outlet 70–80℃, with antioxidant wall material) or vacuum/freeze-dried to brownish-yellow to brown powder (2%~20% Yohimbine).

⑥ High-purity Monomer (≥98% Base / HCl)

Route A (Base Recrystallization): Standardized extract dissolved in hot anhydrous EtOH/MeOH/EA, add 0.1%–0.5% activated carbon (40–60℃ stir) → hot filter → slow recrystallization at 2–5℃ → filter crude → repeat EA/EtOH-H₂O recrystallization 2–3× → vacuum dry (≤40℃) to white/off-white Yohimbine base (≥98% HPLC), related (Pseudo/α/β)<0.1%–0.5%.
Route B (Yohimbine HCl Salification): Base/high-pure extract dissolved in dilute HCl-EtOH, adjust pH 3–4 to form salt → conc. → recrystallized from EtOH-H₂O / acetone-H₂O → filter to Yohimbine Hydrochloride (≥98%~99% white crystals) with improved water solubility. Process light/humidity (hygroscopic salt) / N₂ protected.

⑦ QC & Packaging

Assay by HPLC (Yohimbine, Pseudoyohimbine, α/β-Yohimbine, Corynanthine & related alkaloids), chiral purity assessment; UV auxiliary; LOD, heavy metals (Pb≤1–10ppm), acid radical (Cl⁻/SO₄²⁻) residue, residual solvents (EtOH/MeOH/EA), microbes. Powder/crystals: double PE + amber glass/foil (N₂/vac); strictly light-protected, 2–8℃ or -20℃ (alkaloids light-degradable, HCl salt hygroscopic); shelf life 24 mos.
