摘要:以掌叶梁王茶叶为原料,研究其水提物的急性毒性及半数致死量LD50。结果表明:梁王茶水提物经口LD50>15000 mg/kg·bw,
属于实际无毒物质。与对照组相比,灌胃 2521~15000 mg/kg·bw 梁王茶水提物对雌性和雄性小鼠的体重增量无显著影响(p>0.05),
对雌鼠心、脾和肺脏器系数、血清 ALT、AST 和肌酐水平均无显著影响(p>0.05),对雄鼠肺和肾脏器系数、血清 ALT 水平均无显著
影响(p>0.05)。极高剂量梁王茶水提物使雌性(剂量≥7350 mg/kg·bw)和雄性(剂量≥5145 mg/kg·bw)小鼠的血清尿素水平显著高
于空白对照组(p<0.05),说明极高剂量梁王茶水提物对肾脏有一定毒性。急性毒性研究表明,梁王茶水提物经口 LD50>15000 mg/kg·bw,
属于实际无毒物质,极高剂量时其对肾脏有一定毒性。

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.

我国主要有 2 种即异叶梁王茶[Nothopanax davidii
(Franch.) Harms ex Diels]和掌叶梁王茶[N.delavayi
(Franch.) Harms ex Diels][3,4]。
梁王茶具有较高的药用价值[5],常被人们当作时
蔬食用,如在阳宗境内有着“茶不泡水当道菜”
[1]。梁
王茶嫩茎叶不仅可作为蔬菜食用[6],还可制成梁王茶
干叶泡水喝[7],其树皮被用来提取栲胶,树叶常被用
来驱杀害虫[7]。梁王茶作为药用材料时,有清热、祛
风除湿药活络、治疗喉咙肿痛等作用[8,9]。另据报道,
梁王茶多糖也有较好的双向免疫调节、抗氧化应激和
