The theory is mathematical in the strictest possible sense. The mathematics involved is strictly digital—not quantitative in the manner that what is usually thought of as mathematics is quantitative. It is anticipated at this time that the exclusively digital nature of rational human intelligence exhibits four flavors of digitality, apparently no more, and that each flavor will require a lengthy study in its own right.

芥菜(Brassica juncea(L.)Czern et Coss)属十字花科(Cruciferae)芸薹属(Brassica)的药食两用蔬菜。该研究概述了芥菜的烃类、黄酮类、酚酸类、多糖等多种化学成分及其抗肿瘤、抗癌、抗氧化、清除自由基、降血糖、杀虫抑菌等生物活性方...芥菜(Brassica juncea(L.)Czern et Coss)属十字花科(Cruciferae)芸薹属(Brassica)的药食两用蔬菜。该研究概述了芥菜的烃类、黄酮类、酚酸类、多糖等多种化学成分及其抗肿瘤、抗癌、抗氧化、清除自由基、降血糖、杀虫抑菌等生物活性方面的研究进展,旨在为芥菜的深入研究与开发提供参考。展开更多
目的:采用PMP(1-苯基-3-甲基-5-吡唑啉酮)柱前衍生化-HPCE法测定多糖的单糖组成,探讨不同种源霍山石斛、铜皮石斛及野生河南石斛药效物质基础的相似性。方法:采用石英毛细管柱(100 cm×50μm),350mmol/L硼酸溶液(以1.0 mol/L Na OH...目的:采用PMP(1-苯基-3-甲基-5-吡唑啉酮)柱前衍生化-HPCE法测定多糖的单糖组成,探讨不同种源霍山石斛、铜皮石斛及野生河南石斛药效物质基础的相似性。方法:采用石英毛细管柱(100 cm×50μm),350mmol/L硼酸溶液(以1.0 mol/L Na OH溶液调至p H 10)为缓冲液,运行电压20 k V,柱温为25℃,检测波长250 nm,运行时间34 min。结果:5种石斛样品共检出木糖、葡萄糖、甘露糖、半乳糖、半乳糖醛酸和核糖6种单糖。相似度评价显示,同一种源石斛样品10个批次间的相似度均在0.98以上,但不同种源的霍山石斛、铜皮石斛及野生河南石斛单糖组成及含量明显不同。结论:多糖部位PMP柱前衍生化-HPCE法具有简单、快速、准确、重现性好等优点,为不同种源的霍山石斛、铜皮石斛与野生河南石斛的定性鉴别及药材内在质量评价提供新的参考依据。展开更多
文章报道了新种屏边开口箭T.pingbianensis J.L.Huang et X.Z.Liu及其核型和花粉形态。屏边开口箭的核型公式为2n=38=14m+10sm+8st+6t,具明显的二型性,属3C型。花粉粒为球形,无萌发孔沟,外壁具皱块状纹饰。从花结构、核型和花粉形态上看...文章报道了新种屏边开口箭T.pingbianensis J.L.Huang et X.Z.Liu及其核型和花粉形态。屏边开口箭的核型公式为2n=38=14m+10sm+8st+6t,具明显的二型性,属3C型。花粉粒为球形,无萌发孔沟,外壁具皱块状纹饰。从花结构、核型和花粉形态上看,屏边开口箭和伞柱开口箭T.fungilli-formis Wang et Liang亲缘关系近,而且伞柱开口箭比屏边开口箭在一系列特征上都较特化。展开更多
