St. John's wort extract raw material rose nearly three times as much

In 2011, St. John's wort's stalk production was not very large, and the prices fluctuated sharply during the new period of production. In the current market, the price of stems and leaves of St. John's wort has been in the range of RMB 12-14 per kilogram, which was only around RMB 4 per kilogram in the same period of last year. The content of 0.3% of total hypericin was RMB 120-140 per kilogram. between.

In recent years, industry has found that St. John's wort extracts are also adulterated. International buyers generally need 0.3% of total hypericin, and the industry generally uses UV analysis to define the content, so some companies use bright melanin to increase the absorbance, not only greatly affected the reputation of China's phytosanitary industry, Also undermined the market order of China's phytosanitary industry. Although the current rise in raw materials is three times as much as in the same period of last year, it is very difficult for producers to raise prices. The main reason is that counterfeit goods are used as counterfeits. However, at present, buyers are beginning to increase the use of high-performance liquid-phase assays to further define hypericin and pseudo-hyperiurin in the extract of St. John's wort, which can be used for preliminary and effective identification.
