This study was conducted to examine effects of plant growth regulators and light resources on the formation of multiple shoot and plant regeneration of Hovenia dulcis var. koreana Nakai. Stem and shoot tip were cultured on MS medium or WPM supplemented with various plant growth regulators. At the single treatment, the highest shoot formation was obtained when stem explants were cultured on WPM supplemented with kinetin $1.0mg{\cdot}L^{-1}$. MS medium containing NAA 0.1 and TDZ $0.1mg{\cdot}L^{-1}$ gave the best results for shoot induction rate and shoot growth in combination treatments. Of the BAP and kinetin tested, BAP $0.5mg{\cdot}L^{-1}$ on WPM was found to be more effective for shoot growth from shoot tip. Under white fluorescent light treatment, shoot growth was much higher than blue, red LED treatments. Root induction from in vitro growth of plantlet was the best on WPM supplemented with $1.0mg{\cdot}L^{-1}$ IBA. The results suggest that selection of plant growth regulators and light resources could be important factor to achieve an efficient in vitro growth.

헛개나무의 추출물을 이용하여 alcohol과 acetaldehyde, fusel oil류 대한 분해효과를 검정한 결과 alcohol 분해 및 숙취해소에 효과가 높은 것으로 확인하였으며, 체내 독성물질 제거를 위한 GST activity를 측정한 결과 헛개나무 추출물이 GST 효소와 비교 시 약 2배 정도의 활성을 나타내었다. 또한 헛개나무 추출물의 간암세포의 성장에 미치는 효과를 알아본 결과 $1\;mg/m{\ell}$에서 간암세포의 성장을 억제하는 것을 확인하였다.
