Our laboratories select an appropriate solvent ratio, according to the solubility of the actives in the herb, in order to extract the desired spectrum of components. Extraction of herbs most commonly involves a combination of ethanol and pure water.
By carefully selecting the extraction solvents and ratio unique to each herb, the maximum extraction of the constituents of each herb can be achieved providing practitioners with a high quality product they can prescribe with confidence.
Verification and identification of raw material
The raw material we receive is authenticated and positively identified using the most sophisticated test appropriate for each herb and whether it is whole, chopped, powdered or an extract. The tests include one or more of the following:
physical assessment (sight, touch, smell, taste)
Fourier Transform Infared Spectroscopy (FTIR)
Ultra violet/Visible Spectrophotometry (UV/VS)
Polymerase Chain Reaction (PCR)
Thin Layer Chromatography (TLC)
Gas Chromatography (GC)
Mass Spectrometry (MS)
High Performance Chromatography (HPLC).
Quality control testing
At different stages during the manufacturing process, further chromatographic testing is conducted to ensure the presence, and required levels, of active constituents of the herbs. The most frequently utilised testing procedures at our laboratories are:
- Thin Layer Chromatography (TLC)
TLC separates the chemical constituents of the herb and allows them to be compared to a reference for positive identification of the herb. Chromatographic techniques contribute to the quality control of herbal medicines and are valuable for authentication and identification of the herbal products. They provide a chemical “fingerprint” unique to each herb.
Gas Chromatography (GC)
GC is the analytical method of choice for the determination and identification of volatile compounds in herbal medicines. Volatile oils are important compounds in many medicinal herbs and their detection by GC is an important part of analysis and quality control.
- Mass Chromatography (MC)
MC is a highly sensitive and selective technique that identifies the molecular weight and structure of compounds found in herbal medicines.
- High Performance Liquid Chromatography (HPLC)
HPLC is one of the most commonly applied techniques used in the analysis of herbal medicines and can determine the majority of chemical constituents found in herbal medicines. It gives a fingerprint of the herbal constituents so they can be identified and quantified.
Microbiology and heavy metal testing
BioCeuticals conducts microbiology testing for bacteria, yeasts and moulds as well as heavy metals, pesticides and aflatoxins. All products must meet strict criteria set by the TGA to ensure the production of a safe, reliable and effective product.
Final quality control
Once our products are ready to be packaged and released for supply, further quality control testing occurs for stability of the product. Further to our commitment to quality, the entire BioCeuticals herbal range:
contains no artificial colours, flavours or sweeteners uses only sustainable herbal ingredients features clinically trialled and proven ingredients, using standardised extracts where appropriate.
Our quality control testing ensures that you can focus on treating your patients. BioCeuticals guarantees our herbal medicines to be of the highest quality.
