High Performance Liquid Chromatography

“Fingerprint Technology”

SCU is a pioneer in the use of fingerprint mapping technologies such as High Performance Liquid Chromatography (HPLC) to identify and determine the authenticity of the Daemonorops Draco Blume raw materials, test for active constituents, and ensure its potency. HPLC is an advanced technology used to authenticate bio-specimens in modern biotechnology and biochemistry as all living things have a unique ‘fingerprint’, comprising certain quantities of active constituents.

Characteristic identification: Peak 1 (0.7500.063), peak 2 (0.9680.071), peak 3 (1.0001.000), peak 4 (1.0210.177),peak 5 (1.0350.093), peak 6 (1.0670.535), peak 7 (1.1220.084), peak 8 (1.3010.185), peak 9 (1.3430.192), peak 10 (1.4340.058), peak 11 (1.4780.792), peak 12 (1.7610.066), peak 13 (1.8110.173).

After HLPC analysis, the Daemonorops Draco Blume raw materials are graded by SCU using its own unique grading system which allows the Company to assess and determine optimal yields and minimise wastage. SCU uses the HPLC technology to determine the concentration of active compounds in each batch of Daemonorops Draco Blume raw materials for the determination of its grade.

The graded Daemonorops Draco Blume raw materials are later outsourced to a processing partner for the processing of Resina extract and the cost for each batch being processed is determined by its grade. After processing, SCU will test the quality of the Resina extract to ensure that it falls within the specifications of the China Pharmacopoeia Commission, before it is packaged and distributed to customers.

Similarly to Resina, SCU will use Fingerprint mapping technologies such as High Performance Liquid Chromatography (HPLC) to identify and determine the authenticity of the Dendrobium, test for active constituents and ensure its potency.
