To explore the toxicological profile of methanol extract of chlorophytum alismifolium (MECA) tubers in Wistar rats. Methods: MECA was subjected to acute and sub-acute studies which were conducted according to Organization for Economic Co-operation and Development (OECD 425 and 407 guidelines respectively). In the acute toxicity experiment, a limit test (5000 mg/kg) was administered to five rats and monitored for 2 weeks. The sub-acute studies were conducted on 4 groups of rats. The first group served as control, while the 2nd, 3rd and 4th groups received MECA (150, 300 and 600 mg/kg respectively). The treatments were given orally and daily for 4 weeks. At the end of the experiment (29th day), the animals were euthanized to obtain blood samples and organs for haematological, biochemical and histological evaluations. Results: Acute toxicity study showed that the oral median lethal dose was >5000 mg/kg. In the sub-acute studies, the results showed no significant (P>0.05) changes in the haematological, hepatic and renal indices compared to control animals. In the fourth week, a significant (P<0.01) increase in body weight of the rats was observed at 150 mg/kg and 600 mg/kg compared to week one. However, there were no major changes in the organ/body weights of the rats. Histological examination of the kidney showed slight glomerular adhesion and tubular distortion. Moderate hepatic necrosis was observed at 150 mg/kg and 300 mg/kg. Conclusions: The results of this research revealed that the MECA tubers is virtually non-toxic after acute administration and it has low sub-acute toxicity potential in rats.

Journal of Northeast Agricultural University(English Edition) 2011年第4期18卷 21-25页

作者： WU Lijun LI Muzi YANG Xue YANG Tao WANG Jingang College of Horticulture Northeast Agricultural University Harbin 150030 China

chlorophytum leaves were treated with three kinds of chemical mutagen, EMS, DES and NaN3 with different concentration to obtain the variation materials with excellent properties. The results showed that the genetic similarity coefficient of variation plants with EMS treatment was between 0.648 and 0.868, with NaN3 treatment was between 0.598 and 0.859, and with DES treatment was between 0.668 and 0.904, of which the mutagenic effects with 0.8% EMS, 250 mg. L-1 NaN3 and 0.3% DES on chloro- phytum were the best. ISSR molecular marker technique was used to analyze their genetic diversities. Total 392 polymorphic bands were obtained through 18 ISSR primers. Polymorphic ratio was 72.4%, which showed that DNA mutation took place in various degrees
