在北京,本世纪初出现了一种外来入侵植物——刺萼龙葵。这种植物起源于北美洲,全植株有毒,含有茄碱(一种神经毒素);另一方面,茄碱又有抑瘤等功效。为了在熟悉刺萼龙葵的毒害程度、治理这种外来入侵植物的同时,能够废物利用,从中有效获得茄碱等有药理或经济价值的成分,通过检测全植株提取物对肿瘤细胞(H22)膜ATPase活力的抑制效应,并对照茄碱、传统化疗药物环磷酰胺的功效,对北京外来入侵植物刺萼龙葵抑瘤效应进行了评估。结果发现,北京自然界已入侵生长的刺萼龙葵的细胞毒性约相当于3.63 mg/g茄碱的当量,大约相当于(或略高于)马铃薯嫩芽的茄碱当量。因此,实行废物利用,从入侵生长的刺萼龙葵中获得茄碱(等药用成分)大有作为,可以在治理生态中获得经济效益,并解放出马铃薯等具有其他重要经济价值作物的生产力。
In Beijing, a invasive alien plant called Calyx was found at the beginning of this century. This plant originated in North America, the whole plant toxic, containing solanine (a neurotoxin); the other hand, solanine and tumor suppressor and other effects. In order to be familiar with the degree of poisoning of Solanum glaucum, it is able to treat the alien plants and utilize the wastes effectively to obtain pharmacologically or economically valuable components such as solanine. By detecting the effect of the whole plant extract on tumor cells (H22) Membrane ATPase activity of the inhibitory effect, and control the solanine, the traditional chemotherapy drug cyclophosphamide efficacy of invasive alien plants in Beijing Calyx nigriculture antitumor effect were evaluated. The results showed that the cytotoxicity of Solanum lycopersicum which had been invaded by nature in Beijing was approximately equivalent to 3.63 mg / g solanine equivalent, which was equivalent to (or slightly higher than) the solanine equivalent of potato sprout. Thus, the implementation of waste utilization, access to solanum lycopersicum (Solanum lycopersicum and other medicinal ingredients) can do much to gain economic benefits in managing ecology and free up the productivity of crops of other important economic value, such as potatoes.
