Chemical profiles and identification of key compound caffeine in marine-derived traditional Chinese medicine Ostreae concha

To compare the chemical differences between the medicinal and cultured oyster shells, their chemical profiles were investigated. Using the ultra performance liquid chromatography-electron spraying ionization-mass spectrometry (UPLC-ESI-MS), combined with principal component analysis (PCA) and orthogonal projection to latent structures discriminant analysis (OPLS-DA), the discrimination of the chemical characteristics among the medicinal and cultured oyster shells was established. Moreover, the chemometric analysis revealed some potential key compounds. After a large-scale extraction and isolation, one target key compound was unambiguously identified as caffeine based on extensive spectroscopic data analysis (1D and 2D NMR, MS, and UV) and comparison with literature data.     

Biocultural Diversity of Sarangani Province,Philippines: An Ethno-Ecological Analysis

This paper discussed effects of lowland-associated influences on upland ecology, food security and biocultural diversity in the Sarangani farming communities of the Philippines. In the uplands of Sarangani Province, the conservation of traditional rice varieties, the centrality of rice in tribal life, and the continued observance of planting rituals attest to its cultural significance and convey a common desire for cultural preservation and community solidarity. Economic and socio-political pressures had transformed tribal communities, although vestiges of traditional farming systems are still being practiced in remote sitios(villages). Changing land use patterns had also resulted in shrinking farm sizes and consequently in food insecurity in the Sarangani uplands. Extractive industries(i.e. logging, mining and charcoal making) and swidden farming were observed to cause widespread environmental degradation, while modern agriculture had undermined the capacity of indigenous peoples to survive because of their complete dependence on lands and resources. With the reality that cultural and biological diversities are inextricably linked, trans-disciplinary strategies coupling indigenous knowledge systems with scientific knowledge should, therefore, be instituted to save the Sarangani upland ecosystem, the indigenous peoples and their tribal resources.

"南京紫金山地区大型真菌资源调查"之七——本地灵芝科的14个种

2003年,刊登在原《南京农专学报)第一期的"南京紫金山地区大型真菌资源生态环境及其分类鉴定"一文中,曾就灵芝科的16个种做过报道,它们分别隶属于灵芝科的灵芝属,本文发表的图片仅是内中的14种。其中的灵芝、紫芝、树舌和松衫灵芝分别与被广泛应用于现代医药制剂和保健品生产的4个灵芝种相同;我国古代把灵芝等6种芝列为中药中的上品,用于治病和保健,已经延续了很多世纪;而且,灵芝在我国一直被视为吉祥如意的象征。
