The 3～(rd) International Conference on Natural Products :Natural Products -a Must for Human Survival ABSTRACTS

作者： Shixiang Bao, Biwen Wu, Huiqin Huang institute of tropical Biosciences and biotechnology, chinese academy of tropical agricultural Science, haikou 571101, china

Natural product research is increasingly turning to marine animals, plants and microbes as source organisms. Sponges are the most primitive of the multicelled animals that have existed for 700-800 million years, and are proving to be extremely valuable and potentially economically important sources of compounds useful to the pharmaceutical industry. During the last 20 years, numerous novel compounds have been isolated from marine sponges and many of these compounds showed pronounced biological activity. This review summarized the natural active products from marine sponges with antitumor, antiviral and antibacterial activity and the strategies for producing sponge biomass.

The family Ganodermataceae comprising more than 200 fungi species is mainly distributed in the tropical and subtropical areas of Asia,Australia,Africa and America,among which more than 100 species grow in china and 78 wild species were found in Hainan *** chemical investigation on the fruiting bodies of Ganoderma tropicum(Jungh.) Bres.,wild "Lingzhi"genus in Hainan Province,led to the isolation of thirty two compounds (1-32) including four new compounds by column chromatography on silica gel and sephadex *** structures mainly including triterpenes,steroids and xanthones were elucidated by NMR analysis as well as comparison with those reported in the literatures,and were reported for the first time from Ganoderma *** was found for the first time from Ganoderma species,which maybe one of the important natural pigment contributed to the yellow color of the fruiting bodies of *** bioassay of cytotoxic activities of nine compounds was evaluated against five human tumor cell lines HL-60,SMMC-7721, A-549,MCF-7,and ***(1) displayed obvious cytotoxic activities on HL-60, SMMC-7721,A-549,MCF-7 and SW-480 with IC50 values of 7.49,9.04,4.44,21.61 and 14.02μmol.L,respectively.22E-7α-methoxy -5α,6α-epoxyergosta-8(14),22-dien-3β-ol(10) also exhibited definite cytotoxic activities on HL-60,MCF-7,and SW-480.

Journal of Wuhan University of Technology(Materials Science) 2011年第5期26卷 807-811页

作者：彭政罗勇悦 chinese agricultural Ministry Key Laboratory of tropical Crop Product Processing Agricultural Product Processing Research InstituteChinese Academy of Tropical Agricultural Sciences

Natural rubber （NR）/multi-walled carbon nanotube （MWCNTs） composites were prepared by combining self-assembly and latex compounding *** acid-treated MWCNTs （H2SO4：HNO3=3：1,volume ratio） were self-assembled with poly （diallyldimethylammonium chloride）（PDDA） through electrostatic *** the second assembling,NR/MWCNTs composites were developed by mixing MWCNTs/PDDA solution with NR *** results show that MWCNTs are homogenously distributed throughout the NR matrix as single tube and present a great interfacial adhesion with NR phase when MWCNTs contents are less than 3 wt%.Moreover,the addition of the MWCNTs brings about the remarkable enhancement in tensile strength and crosslink density compared with the NR host,and the data peak at 2 wt% MWCNTs *** more MWCNTs are loaded,aggregations of MWCNTs are gradually generated,and the tensile strength and crosslink both decrease to a certain extent.

Development and Conservation of Agrodiversity by Small Farmers: A Case Study from Yunnan, Southwest china

引用

云南植物研究 2001年第S1期23卷 59-68页

作者： CHEN Ai-Guo 1 DAO Zhi-Ling 2 GUO Hui-Jun 1 FU Yong-Neng 1 (1 Xishuangbanna tropical Botanic Garden, chinese academy of sciences, Mengla 666303 china 2 Kunming institute of Botany, chinese academy of sciences, Kunming 650223 china)

Yunnan is the most both biodiverse region in china. An existing project of People, Land Management and Environmental Change of United Nations University aims to document the status of agrodiversity as a basis for meeting local needs, using Xishuangbanna and Baoshan as case studies. Studies reveal that a rich agrodiversity at levels of crop species and varieties, plant species in agricultural fields and diversified ecosystems have been developed and conserved through agricultural systems by small farmers. Social-economic influences on agrobiodiversity are quite complex, but land tenure, household income and farmer association have played an important role in management of agrodiversity.

Phytochemical studies on the stem of Dracaena cambodiana led to the discovery of two new biflavonoids,8-methylsocotrin-3’-methoxy-4’-ol(1) and 8-methylsocotrin-4’-methoxy-3’-ol(2),together with a known biflavonoid,8-methylsocotrin-4’-ol(3).Their structures were identified by means of HRESIMS and detailed spectral analysis(UV,IR,1D and 2D NMR).
