In the course of evaluation of hepatoprotective components against alcohol-induced toxicity from Aloe spp., the methanol extract was found to cause a significant inhibition of rat liver cytosolic alcohol dehydrogenase activity. Systematic fractionation of active tractions monitored by bioassay led to isolation of four compounds; aloe-emodin, aloenin, ethylidene-aloenin and ${\beta}-sitosterol$, which were estimated as active principles for inhibition of c-ADH and c-ALDH activities in vitro.

For the purpose of evaluating protective components against alcohol-induced toxicity, the active components enhancing alcohol metabolism was pursued from water soluble fraction by ethanol precipitation and DEAE-cellulose chromatographic technique. As a result, various high molecular weight fractions from Aloe vera and Aloe arborescens, on a single oral administration in rats were found to cause a significant decrease in the blood ethanol concentration as well as enhancement of liver cytosolic ADH and ALDH activities and among which, a strong acidic high molecular weight fraction was demonstrated to exhibit the most potent enhancing activity on ethanol metabolism.

본 연구는 3개의 색소체 matK, trnL-F, rbcL DNA 염기서열과 1개의 핵 ITS DNA 염기서열을 근거로 한국산 Aloe 3종 A. arborescens, A. vera 그리고 A. saponaria 등과 하나의 변이종 알로에의 유전적 상관관계를 알고자 수행되었다. 전체 2,420 bp 서열이 증폭되었다. 두 개의 삽인-결실(indel)이 trnL 지역에서 확인되었고, 또한 여러 개의 종 특이적인 염기자위가 전체 29개의 최소변이 정보지역(parsimonious informative site)에서 확인되었다. 조사된 한국산 4 종간에는 148 염기변이 지역이 있었으며, 세계산 Aloe 종들을 포함한 비교해서는 170개의 변이지역 중 75개의 최소변이 지역이 확인되었다. UPGMA를 이용한 phenogram에서 새로운 변이종 알로에는 A. vera와 가장 가깝게 유집되었다. 변이종 알로에는 아직까지 보고된 어떤 종류의 Aloe속내 종과 형태적 및 유전적으로 일치하지 않았다. 조사된 알로에 종들의 유집분석 결과는 기존의 연구결과와 일치하였다.

This study was carried out to investigate the effect of polyamines, salt strength. sucrose and gelling agents on the regeneration of plantlets by meristem culture of Aloe arborescens Mill. and Aloe vera L.. Shoot multiplication was more effective when 10mg/ l spermine in Aloe arborescens and 1mg/ l spermidine in Aloe vera added into MS medium than when other polyamines were treated into media. A quarter strength of MS medium was effective for rooting of shoots regenerated. Higher concentration of sucrose (45g/ l) was more effective for shoot regeneration. Addition of 4g/ l gelrite into the medium was effective for induction of multiple shoots from Aloe than that of agar or other concentrations of gelrite. When plantlets regenerated from meristem culture were transferred to pot. survival rate of plantlets was 80% on perlite and was 95% on vermiculite. respectively.

As an initial step for evaluating hepatoprotective components against alcohol-induced toxicity, the effect of various fractions from Aloe vera on alcohol metabolism in rats were examined and the results were as follows: Water soluble fraction, after a single oral administration to rats, was found to cause a significant decrease in the serum ethanol concentration as well as enhancement of liver cytosolic ADH activity. On the other hand, the fractions soluble in organic solvent was found to cause an increase in the blood ethanol concentration and inhibit ADH activity. Further fractionation of the water soluble fraction by ultrafiltration system gave four subfractions corresponding to molecular weight and treatment of them in rats demonstrated that subfraction of M.W. > 30,000 exhibited the most potent enhancing activity of ethanol methabolism.

건강기능식품은 인체에 유용한 기능성을 가진 원료나 성분을 사용하여 정제, 캅셀, 분말, 과립, 액상, 환등의 형태로 제조 가공한 식품을 말한다. 2004년 '건강기능식품에 관한 법률‘이 제정되었지만 아직은 시작단계이며 소비자의 피해나 섭취 후 부작용에 대한 문제도 많이 발생하고 있다. 건강기능식품 중 비교적 높은 부작용 발생 빈도를 보이는 건강기능식품의 주원료인 식물성 원료 14종 37개 품목과 알로에분말 제품 4개 품목을 대상으로 미생물 분석을 하였으며, PSL을 이용하여 알로에분말 제품의 방사선조사 가능성 여부를 알아보았다. 식물성 원료 총 14종 37개 품목에서 세균수는 $10^{3}-10^{6}\;CFU/g$ 검출되었으며, 대장균군은 검출한계(<10 CFU/g)에서 31개 품목에서 $10^{2}-10^{5}\;CFU/g$ 검출되었다. 식중독균은 E. coli와 Salmonella spp., Staph. aureus는 검출되지 않았으며, B. cereus는 8종 12개 품목에서 검출되었다. 알로에 분말제품 4개 품목 중 1개 품목에서만 세균수 $10^{4}\;CFU/g$, 대장균군수는 $10^{3}\;CFU/g$ 검출되었고, 식중독균은 검출되지 않았다. PSL을 이용하여 알로에 분말제품의 방사선조사 가능성을 monitoring한 결과, 알로에 분말제품은 4개 품목 중 positive 2개 품목, negative 1개 품목, intermediate 1개 품목이었다.
