pure artichoke extract

Pure artichoke extract rarely means one thing across different suppliers. The practical definition hinges on what the manufacturer chooses to track and standardise. In Hunan Huacheng Biotech’s case, the focus is on the native polyphenol complex as it exists in the fresh leaf, without fractionation or spiking with isolated acids. The powder carries a light olive-brown colour and a hygroscopic character that needs proper double-lining if it ships to humid climates. Standard solubility testing in cold water passes without the need for a wetting agent, which helps when blending with dry pre-mixes for effervescent tablets or powdered drink sticks. The extract also performs well in acidified systems, remaining clear in solutions down to pH 3.2 after a brief cool-down period. That behaviour comes from the gentle vacuum concentration step, which avoids caramelising the sugars naturally present in the leaf. Quality control tests include heavy metals below 10 ppm lead and a microbial panel that meets USP <2021> limits, backed by the facility’s FDA registration and BRC certification. For a budget-conscious operation, the direct access to the manufacturing site in Hunan cuts out broker mark-ups. Buyers receive the same lot-by-lot documentation regardless of order size, from a 1 kg sample pouch to a 25 kg fibre drum. The cynarin marker stays at 2.5% ± 0.2%, and the moisture content is held below 5% to extend shelf life without extra preservatives. Inventory is kept in a temperature-controlled warehouse, so lead times stay around 10–15 working days after confirmation of the purchase order.
