摘要:以掌葉梁王茶葉為原料,研究其水提物的急性毒性及半數(shù)致死量LD50。結(jié)果表明:梁王茶水提物經(jīng)口LD50>15000 mg/kg·bw,
屬于實(shí)際無(wú)毒物質(zhì)。與對(duì)照組相比,灌胃 2521~15000 mg/kg·bw 梁王茶水提物對(duì)雌性和雄性小鼠的體重增量無(wú)顯著影響(p>0.05),
對(duì)雌鼠心、脾和肺臟器系數(shù)、血清 ALT、AST 和肌酐水平均無(wú)顯著影響(p>0.05),對(duì)雄鼠肺和腎臟器系數(shù)、血清 ALT 水平均無(wú)顯著
影響(p>0.05)。極高劑量梁王茶水提物使雌性(劑量≥7350 mg/kg·bw)和雄性(劑量≥5145 mg/kg·bw)小鼠的血清尿素水平顯著高
于空白對(duì)照組(p<0.05),說(shuō)明極高劑量梁王茶水提物對(duì)腎臟有一定毒性。急性毒性研究表明,梁王茶水提物經(jīng)口 LD50>15000 mg/kg·bw,
屬于實(shí)際無(wú)毒物質(zhì),極高劑量時(shí)其對(duì)腎臟有一定毒性。

Abstract: Leaves of Nothopanaxdelavayi (Franch.) Harms ex Diels (LWC), was used as raw material, the acute toxicity and half lethal
dose (LD50) of its water extract was investigated. Results showed that the oral LD50 of LWC water extract was higher than 15000 mg/kg.bw,
which is actually non-toxic substance. Comparing to control group, gavage of 2521~15000 mg/kg·bw LWC water extract had no significant
effect on the weight gain of both female and male mice (p>0.05), showing insignificant influence on organ coefficients of heart, spleen and lung,
serum ALT, AST and creatinine level of female mice (p>0.05), neither were lung and kidney organ coefficients, serum ALT of male mice
(p>0.05). The serum urea level of female (dose ≥7350 mg/kg·bw) and male (dose ≥5145 mg/kg·bw) mice was significantly higher than that of
the blank control group (p<0.05), indicating that the very high dose of LWC tea water extract had a certain toxicity to the kidney. In summary,
acute toxicity studies have shown that the oral LD50 of LWC water extract is more than 15000 mg/kg·bw, which is a practically non-toxic
substance, however it is toxic to the kidneys at extremely high doses.
