New Group Standard of Silymarin Extract Released New Standard for Selecting High quality Liver Care Products

In the fast-paced life, many "exploding liver" ways, such as staying up late, indulging in entertainment and unwilling to sleep, affect people's liver health. As a common raw material for liver protection, the natural plant silymarin is favored. The liver protection market has expanded rapidly, and there are many related products. However, due to the uneven quality, the public can not choose the best one.

Recently, in order to improve the quality of raw materials and related products of silybum extract, and promote the high-quality development of the nutrition and health industry, the China Association for Industry University Research Cooperation officially released the group standard of Quality Requirements for Silybum Extract (T/CAB 0277-2023), which divides the quality of silybum extract into two levels: "high quality" and "qualified", On the content standard of the characteristic ingredient silymarin, it is proposed for the first time that the high quality level of silymarin extract should meet the content requirements of 40.0%~65.0%; Based on the quality requirements of European Pharmacopoeia and British Pharmacopoeia for silymarin content of 30.0%~65.0%, some indicators such as microbial limit and solvent residue are more strictly limited for qualified silymarin extract.

It is reported that this group standard is the first quality requirement for silymarin extract applicable to dietary supplements in China.

The group standard "Quality Requirements for Silybum Extract" issued this time was drafted by the China National Institute of Standardization, Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, China Institute of Inspection and Quarantine Sciences, Tang Chenbeijian, a leading enterprise in Chinese dietary nutrition supplements, and Yidina, a world-famous plant active ingredient extraction manufacturer Internationally recognized testing and inspection certification body, SGS-CSTC Standards Technical Services Co., Ltd., well-known raw material manufacturer in the industry, Jiangsu Jianjia Pharmaceutical Co., Ltd. and other authoritative organizations and enterprises participated in the completion.

Some studies have shown that due to factors such as origin and process, the content of characteristic components in the extract of Silymarin varies greatly, which may greatly affect its functionality and safety. At the same time, different detection methods will also affect the test results of the content of its index components. Previously, the quality evaluation standards for raw materials and related dietary supplements of silymarin in China have been missing.

Lan Tao, associate researcher of China Institute of Standardization, believes that the group standard provides a standard reference for the research, development, production, processing and other industrial chains of silybum extract and related products, which is conducive to industrial development.
