Study on a Natural Health Drink : Dendrobium Nobile Juice

研究表明，利用铁皮石斛加工成保健饮料石斛汁，石斛生物碱及粘多糖提取率达９０％．石斛汁经毒理试验，结论是石斛汁的小鼠、大鼠急性经口毒性的半数致死量（ＬＤ５０）雌雄两性均大于１０ｇ／ｋｇ体重，按急性毒性分级标准，该样品属实际无毒类；Ａｍｅｓ试验，小鼠骨髓嗜多染细胞微核试验，小鼠精子畸形试验均为阴性．

The present study shows that if we use dendrobium nobile to produce dendrobium nobile juice, a healthprotection drink, the extract rate of alkaloid and mucopolysaccharide in dendrobium nobile can reach 90%. The conclusion of toxicity test of dendrobium nobile juice conducted is that: the half lethal dose(LD50)in acute toxicity test on mice and Wister rats, male or female, is more than 10g/kg weight. According to acute toxicity grading standard, the sample is classified into nontoxicity;Ames test, mouse myeloid cell micronucleus test, mouse teratospermia test all proved it negative.
