[Development and analysis of revitalizing tincture]

Area of Science:

• Pharmacognosy
• Phytochemistry
• Herbal Medicine Production

Background:

• Complex herbal tinctures require optimized extraction methods for consistent quality.
• Traditional herbal preparations often lack standardized production protocols.
• Evaluating key quality parameters ensures the efficacy and safety of herbal extracts.

Purpose of the Study:

• To determine optimal conditions for producing a complex tincture from Hyperici herba, Cinnamomi cortex, Rosmarini folium, Lavandulae flos, and Zingiberis rhizoma.
• To establish quality control parameters for the manufactured tincture.
• To validate the identification of flavonoids using analytical techniques.

Main Methods:

• Optimized extraction using 70% ethanol (V/V) via percolation.
• Controlled particle size for plant materials: 2.0-3.0 mm for leaves/herb/flowers, 0.3-0.5 mm for bark/roots.
• Quality assessment included total flavonoids (as rutin), dry residue, ethanol concentration, density, and microbial load.

Main Results:

• Optimal extraction conditions were identified: 70% ethanol, percolation method, and specific particle sizes.
• The tincture's quality was assessed through multiple physicochemical and microbiological parameters.
• High-performance liquid chromatography (HPLC) confirmed flavonoid identification.

Conclusions:

• The established method ensures the consistent production of a high-quality complex herbal tincture.
• Standardized production and quality control are crucial for reliable herbal medicinal products.
• This research provides a reproducible protocol for manufacturing and evaluating complex tinctures.
