狭域特有珍稀植物茶果樟(Cinnamomum chago)的形态与光合生理特征研究

茶果樟(Cinnamomum chago B.S.Sunet H.L.Zhao)为樟科(Lauraceae)樟属(Cinnamomum)植物。调查发现其局限分布于云南省云龙县、漾濞县一带澜沧江上游各支流山地,所有居群内均无幼树和幼苗,结实率低,种群更新困难。迄今为止,茶果樟的解剖结构和光生态适应的研究处于空白。鉴于此,本文对茶果樟及其同属植物形态解剖进行比较,旨在进一步揭示茶果樟的分类学地位,为樟属的分类提供依据。同时通过遮阴处理,从叶绿素荧光参数、光合作用特征以及形态解剖等方面探讨了茶果樟幼苗对光的生态适应性,为茶果樟的引种栽培提供了重要的参考依据。主要的研究结果如下:茶果樟羽状脉且无离基三出脉可被明显区分;其叶片对生或近对生、侧脉脉腋无腺窝、花序轴各节常单花对生、花药长圆形、花粉粒小刺基部的垫状隆起边缘无颗粒状突起等特征与本文的肉桂组植物相似,本文樟组植物叶片互生、侧脉脉腋有腺窝、花序轴各节有(2-)3花的分支、花药短圆形、...  (本文共84页) 本文目录 | 阅读全文>>

Rapid Extraction and Analysis of Essential Oil from Cinnamomum Cassia Presl.

An improved solvent-free microwave extraction(ISFME) was used for the extraction of essential oil from dried Cinnamomum cassia Presl. Two kinds of solid microwave absorption media[carbonyl iron powder(CIP) and graphite powder(GP)] were used. When ISFME was applied, the heating rate was enhanced and the extraction time was obviously shorter than that consumed in conventional solvent-free microwave extraction(CSFME). T...  (本文共6页) 阅读全文>>

Cinnamomum cebuense的化学成分(英文)

AIM: To investigate the chemical constituents of Cinnamomum cebuense, an endemic and critically endangered tree found only in Cebu, Philippines. METHODS: The compounds were isolated by silica gel chromatography. The structures of the isolates were elucidated by NMR spectroscopy. RESULTS: The dichloromethane (DCM) extract of the bark of C. cebuense afforded a new monoterpene natural product 1 and a new sesquiterpene 2...  (本文共5页) 阅读全文>>
