Product Information
| Description: | Rosmarinic acid (RA, Rosemary acid) is a naturally occurring hydroxylated compound, it has the ability to block complement fixation, inhibit lipoxygenase and cyclooxygenase activity and inhibit the expression of CCL11 and CCR3 by suppressing the IKK-β activity in NF-κB activation signaling. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
