三棱

MethodsGuided by the contents of mannitol in Sparganium stoloniferum, uniform design, response surface analysis and path analysis were used to optimize microwave extraction process by combining with single factor experiment.

方法以甘露醇含量为响应指标，通过均匀试验设计，采用二次响应曲面和通径分析并结合单因素实验优化三棱中甘露醇的微波辅助萃取工艺。

Methods: The various animal models including writhing experiment in mice, rat's toes swelling induced by carrageenan and the increase of capillary permeability in mice induced by acetic acid, were used to determine the effects of compound sparganium stoloniferum capsules.

建立多种动物模型，通过对醋酸所致小鼠扭体反应、角叉菜胶所致大鼠足肿胀、醋酸所致小鼠腹腔毛细血管通透性影响等试验，研究复方三棱胶囊的药理和毒理作用。

Compound sparganium stoloniferum capsules was a safely and efficient drug for treating unpregnant.

复方三棱胶囊治疗不孕症，安全可靠，药效显著。

The calibration curve was linear in the range of 0.003 40～0.02432 mg.ml-1 for rutin. The sample was stable within 8 hours and the recovery rate of rutin was 98.56 %. And in precision test, RSD=1.38%. ConclusionThere is rutin in SFE extract of Sparganium stoloniferum.

结果在三棱的超临界萃取物中含有芦丁成分，建立的液相色谱方法在芦丁浓度为0.003 40～0.02432 mg.ml-1的范围内线性关系良好，样品在8 h内稳定，平均加样回收率为98.56%，以峰面积作精密度实验，RSD为1.38%。

Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有&盾状心皮&的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出&囊状心皮&的特点。
