Figure 1From: Protection against LPS-induced cartilage inflammation and degradation provided by a biological extract of Mentha spicata HPLC chromatogram of aqueous extract [A] and biological extract B] of High-Rosmarinic Acid Mint [HRAM]. [A] The major peak represents rosmarinic acid [RA] at a concentration of 130 ug/mL. [B] Retention times of compounds of interest: Caffeic acid = 6.00 min; Ferulic acid = 10.52 min; m-Coumaric acid = 14.10 min; Rosmarinic acid = 20.50 min.Back to article page
