Result: There were many semipolar, low-polar and nonpolar antimicrobic components in natural products, they diffused slowly in medium, it was possible for false negative and leaked screening by inhibition zone size judging only, but TTC method was better precise and reliable with the sum of indicator size without dyed by TIC and inhibition zone size.

结果：天然产物中存在中极性、弱极性甚至非极性抗菌成分，在培养基中扩散较慢，现行K-B法以透明抑菌圈为判读抗菌活性依据，会低估样品抗菌活性，甚至出现假阴性结果，造成漏筛。以不能被TTC显色的指示菌范围和透明抑菌圈之和来判读天然产物抗菌活性，提高了K-B法检测天然抗菌成分的准确性和可靠性。

However, the taxa of strictly tropical distribution are still underrepresented in the flora of southeastern Yunnan compared to Indo-Malaysian flora, and the families of mainly subtropical to temperate distribution, such as Magnoliaceae, Theaceae, Cornaceae, Styracaceae, Symplocaceae, Aquifoliaceae and Caprifoliaceae, are well represented in the flora. Some characteristic families of temperate East Asia, such as Diapensiaceae, Dipentodontaceae, Eupteleaceae, Grossulariaceae and Toricelliaceae are also present in the flora of southeastern Yunnan.

由於位於东南亚热带北缘山地及其地质历史原因，云南东南部的热带植物区系中严格热带分布的成分不多，仍以边缘热带成分为主，并有相对丰富的亚热带－温带科如木兰科、山茶科、山茱萸科、山矾科、忍冬科、冬青科等以及一些东亚和喜马拉雅特徵科，如岩梅科、十齿花科、领春木科、茶藨子科和鞘柄木科，显示了它与东亚温带植物区系也有较多联系。

Asian (47.4%) and temperate genera mainly constituted by North temperate (50%) and E. Asian (50%). So that the geographical elements are discomplex. In the 25 species of arborous layer, 76% is the middle subtropical zonal type, 16% south subtropical zonal type and 8% north subtropical zonal type, of which the first 6 positions of important value index were all middle subtropical zonal type. This showed that the community was subtropical characteristic. There are 59.5% evergreen and 40.5% deblade of 79 known species in which the mid-phaenerophytes is the first position of all, accounting for 27.8%, and the evergreen broad-leaved species constituted the majority of meso-phaenerophytes which accounts for 15.2%.

乔木层多数优势种为稳定型种群，所以乔木层优势区系成分相当稳定，表明该群落为一种顶极群落。59个种子植物属只有10个分布区类型和4个变型，地理成分不复杂，其中热带分布27属占46.6%，温带分布31属占53.4%；热带分布以泛热带和热带亚洲分布为主，分别占52.6%和47.4%，温带分布为北温带和东亚分布各占50%。25个乔木层树种中，中亚热带地理分布类型的占76%，南亚热带地理分布类型的占16%，北亚热带地理分布类型占8%，重要值指数排列前6名的均为中亚热带地理分布类型，所以该群落为亚热带性质。

Objective Bergenin is the effective ingredient for cough, and maybe Quercetin and Kaempferol are the expectorant ingredient in Ardisia Japonica,.

目的 矮地茶的止咳有效成分为岩白菜素，槲皮素和山奈酚可能为其化痰成分。

English causatives and Chinese causatives can not only express the same concept,but show some similar aspects on the language structure which are reflected on the different components linear arrent in the surface structure and logic relations among the different components and semantic expressions in the deep structure.

汉英致使句不但表述了同样的概念，而且在语言结构上也体现出许多相似之处，主要表现在表层线性成分排列上的对应关系及深层结构各成分之间的逻辑关系及语义表达上。

METHODS The contents of synephrine,neohesperidin,hesperidin, naringin and narirutin in the raw materials and the extracts of Citrus aurantium were determined by reversed-phase high performance liquid chromatography with an Inertsil ODS-3(4.6 mm×250 mm,5 μm) column, respectively.

方法采用高效液相色谱法，以InertsilODS-3(4.6mm×250mm，5μm)色谱柱分别对枳实及其提取物中辛弗林生物碱类成分和新橙皮苷、橙皮苷、柚皮苷、芸香柚皮苷黄酮类成分进行测定。

Result Under the pretreatment conditions, the content of acetone extractives transformed. The hydroxyl and carboxyl, belonging to auxochromic groups, were oxidized into the carbonyl and ester groups. Also, there were plenty of auxochromic groups and chromophoric groups in the acetone extractives of silver chain.

结果］刺槐在预处理条件下，丙酮抽出物成分发生了变化，羟基、羧基等助色基团在预处理条件下氧化成羰基、酯基等发色基团，且丙酮抽出物的主要成分中含有大量发色基团和助色基团。

The paper carries on qualitative analysis to the acetone extractives before and after discoloring, shows the main components of the extractives and then takes comparison. The results shows :①The hydroxyl is oxidized and then shifted to the carbonyl,carboxyl, ester and ketone groups during inducing discoloration under the pretreatment conditions,which makes the wood color deep;② There are plenty of auxochromic groups in the acetone extractives of silver chain, the interaction between the auxochromic groups and the chromophoric groups makes the wood color deep.

摘 要：本文通过对刺槐变色前后丙酮抽出物的定性分析，得出变色前后丙酮抽出物的主要成分，进行对比分析，初步得出抽出物对诱发变色的作用为：①变色前后羟基在预处理条件下氧化成羰基，羧基，酯基和酮基等官能团，使木材颜色加深；②刺槐丙酮抽出物的主要成分中含有大量助色基，这些基团会与木素中的发色基团相互作用，使木材颜色加深。
