Objectives : This study was conducted to investigate the effect of HT008, a multi-herbal mixture consisting of 3 herbs, Eleutherococcus senticosus, Angelica sinensis, and Scutellaria baicaleinsis on arthritic model in rats. Methods : The anti-inflammatory and analgesic activities were observed by utilizing the following models: carrageenan-induced edema of the hind paw of rats, acetic acid-induced writhing response in mice. The perimeter of the paw was measured before injection and then at 1, 2, 4, 6 h after injection of 1% $\lambda$-carrageenan. The HT008 at five dose levels (10, 30, 100, and 300 mg/kg) and distilled water given 30 min to treatment groups and control group, before $\lambda$-carrageenan injection. In the writhing test, the mice received 0.7% acetic acid solution in normal saline injected intraperitoneally at a dose of 10 ml/kg. The number of writhes was counted staring 10 min after injection. Results : HT008 at four dose levels (30, 100, and 300 mg/kg) significantly decreased the carrageenan-induced rat paw edema perimeter. E. senticosus and S. baicaleinsis extracts reduced acetic acid-induced writhing response in mice. Also A. sinensis extracts significantly decreased the carrageenan-induced rat paw edema perimeter. Conclusions : These results show that HT008, a multi-herbal mixture has both anti-inflammatory activity and analgesic effects in vivo arthritic model, and suggest that HT008 could be a good therapy to treat human osteoarthritis.

In this study, baicalin, as a marker substance of Scutellariae Radix, was quantitatively analyzed by a high performance liquid chromatography-photodiode array detector (HPLC-DAD). We identified wogonoside, baicalein, and wogonin in the Scutellariae Radix by a high performance liquid chromatography-electrospray ionization-mass spectrometer (HPLC-ESI-MS). The baicalin was separated on a Xterra C18 column ($5{\mu}m$, $4.6{\times}250mm$) using mobile phase consisting of 38% acetonitrile in 0.68% phosphoric acid. The baicalin spectrum in the Scutellariae Radix extracts was coincided by comparing with UV-visible spectrum (200-550 nm) of baicalin standard in the library. The amount of baicalin in Scutellariae Radix was 10.46%, which is higher than KFDA's guideline. The marker substances of Scutellariae Radix showed a strong base peak $[M]^+$ in the positive detection mode following as; baicalin (m/z; $271[MH^+-sugar]^+$, $447[M+H]^+$), wogonoside (m/z; $285[MH^+-sugar]^+$, $461[M+H]^+$), baicalein (m/z; $271\;[M+H]^+$), wogonin (m/z; $285[M+H]^+$). These results are consistent with the fragment pattern and molecular weight of standard components from literature.
