    Xanthium or cockleburr fruit (Xanthium sibiricum PATR, Asteraceae) is used in Traditional Chinese Medicine for nasal or sinus irritations with a viscous discharge and related headache.[1] Fixed oil, volatile oil, phenolic acids (e.g. chlorogenic, dicaffeoylquinic acid) and sesquiterpenes[1 – 3] are mentioned in literature as chemical constituents. Due to apparent hepatoxicity, also diterpene glycosides, like atractyloside (ATR) and carboxyatractyloside (CATR), are known to be present in the herbal drug material.[1,4,5] ATR was isolated from Xanthii fructus using Sephadex® LH20, centrifugal partition chromatography (CPC) and preparative HPLC. The cell viability in vitro, using the human hepatoma cell line Huh-7 cells with the MTT assay, was examined with isolated ATR, commercial CATR (both 25 to 500µM) and specially prepared decoctions of Xanthii fructus (100 to 750 µg/mL). All three, ATR and CATR and decoctions inhibited, in this in vitro system slightly the cell viability in a dose dependent manner, indicating a low cytotoxicity. As literature data reported of an obviously higher toxic effect of CATR in comparison to ATR[6] further comparative pharmacological analyses of both compounds are mandatory.
