Base on above studies, some conclusions were obtained as follows:(1) ore-forming background of the studied ferromanganese crusts are mainly controlled by intensity of Antarctic Bottom Waters and variations of material source;(2) it is confirmed that the ferromanganese crusts are mainly hydrogenetic and their composition are affected by volcanic and continental material simultaneously; there are no obvious phosphatization reconstruction and element reaction occurred in them, so they have important paleoceanological significance;(3) from researches on element occurrence modes in the new-type ferromanganese crusts and the lying sediments, it is proposed that there is no great biological affection on the crusts formation and their composition mainly came from the adsorptive action of the ferromanganese oxides in them;(4) two major types of ore-controlling factors are identified through compilation of ore-controlling factors, which are geological and oceanic factors;(5) considering the long-term variation trends of the crusts composition, combing the U-series and 10Be isotope dating results, it is proposed that the ore-forming processes of ferromanganese crusts in the studied areas can be divided into three major stages (5.6~2.8 Ma, 2.8~2.7 Ma and since 2.7 Ma), and then the activities of AABW since the Late Miocene, changes of input flux coming from volcanic and continental material are confirmed.
通过研究,得出如下结论:(1)研究区铁锰结壳的成矿背景主要受控于南极底流强弱及物源供给的变化;(2)证实铁锰结壳主要为水成成因,同时其物质组成也受一定程度的火山和陆源物质的影响;结壳自形成以来没有遭受到明显的磷酸盐化等成岩后期改造和元素再迁移,具有重要的古海洋学意义;(3)通过新型铁锰结壳及下伏沉积物元素赋存状态的研究,认为生物作用对研究区结壳的形成并没有很大的直接影响,其物质成分主要来自于结壳中铁锰氧化物的吸附作用;(4)在控矿要素的研究中,归纳出了地质与海洋两大类结壳控矿要素;(5)根据结壳成分长周期变化趋势,结合铀系和10Be测年结果,将研究区结壳的形成过程划分为三个主要阶段(5.6~2.8 Ma,2.8~2.7 Ma和2.7 Ma以来),并确定了晚中新世以来研究区南极底流的活动情况、火山和大陆来源物质输入量的变化。

Now, Flavonoids and ginkgolides were mainly extracted from the leaves of Ginkgo biloba., but the leaves often contain high content of corious and cereous, and the effective constituent is very different under the various conditions. In addition, the constituent of ginkgolides is very low in the leaves, and thus the quality of extraction is difficult to reach the international standards.
目前人们主要从银杏叶中提取银杏黄酮和萜内酯,但由于银杏黄酮和银杏内酯的含量很低,尤其银杏叶中最主要的有效成分银杏内酯B主要存在于根中,在银杏叶中含量极低(<0.1%),且是在生长状态的叶中含量最高,采叶影响树的生长;又因银杏叶中主要的有效成分受多种因素的影响又有很大差别,银杏叶革质化、蜡质化程度高,使得国内银杏叶提取物的质量很难达到国际标准。

Samples were subjected to high pressure ranging from 100 to 500 MPa. After high pressure treatments, the flavour compounds were extracted by Solid-Phase Microextraction. Analysis was carried out by Gas Chromatography-Mass Spectrometry. The key flavour compounds of orange juice were three alkenes (namely limonene, myrcene and α-pinene), two alcohols (linalool and α-terpineol), three aldehydes, one ketone and two esters (ethyl butyrate and 3-OH-ethyl hexanoate).

The contents of mineral elements, like Fe, in LMTCMs were higher than that of nor-LMTCM. The result of analysis of mineral element of 14 LMTCMs by ICP-MS method also showed the content of Fe have something to do with lung meridian tropism effects. The result of the study of platycodon radix approved the laws too. These laws were used to predict if the marine medicines have the lung meridian tropism effects.2. The Compatibility laws of Medicines and their chemical composition in LSP were studied by mining the data of the constituent herbs and their chemical composition. The results showed that the most constituent medicines of lung system prescriptions have lung meridian tropism. Radix glycyrrhizae, herba ephedrae, semen armeniacae amarum, fructus schisandrae Chinese and their compatibility are common in lung system prescriptions. Terpene, alkaloid, steroid, and flavanoid compounds and their compatibility are common in lung system prescriptions.3. The marine phycophyta medicines of LSP were studied by the same method.
