民族药理学相关性：与食品商品相比，草药价值链通常被忽视。毫不奇怪，创收往往偏向链条末端，因此农民和生产者是收入最低的受益者。价值链不仅影响生产者的生计，也影响当地和全球通常销售的产品的成分和质量，从而影响消费者。为了了解价值链对产品成分的影响，我们研究了姜黄（Curcuma longa）的生产条件及其衍生产品的代谢组组成。我们的目标是整合这两个组成部分，以便更好地了解不同价值链对某些生产者生计的影响。材料和方法：这个跨学科项目采用混合方法。案例研究是在印度的两个不同地点进行的。最初通过半结构化访谈和非参与者观察的方式收集草药价值链的数据。从印度、欧洲和美国收集样品，并使用 H-1 NMR 光谱结合多元分析软件和高性能薄层色谱 (HPTLC) 进行分析。结果：我们调查药用植物价值链并解释不同价值链对印度生产者生计某些方面的影响，并首次分析评估不同价值链的化学变异性和质量影响 可能有提供给欧洲最终用户的产品。属于一体化链条的农民可以从中受益，并且所得产品需要接受更高标准的加工和储存。通过使用 HPTLC 和 H-1 NMR 光谱等分析方法，可以将选定生产商的产品成分的一些变化关联起来，并确定某些类型价值链的优势和劣势。这两种分析技术提供了不同且互补的数据，它们一起可用于有效区分各种生药粉末和草药产品。结论：该项目表明，有必要研究所谓“供应国”生产的商品的生产者和消费者之间的联系，并且代谢组学提供了一种评估价值链上化学变异性的新方法。这也有助于理解这对价值链上人们的生计的影响。 (C) 2014 年作者。由爱思唯尔爱尔兰有限公司出版。保留所有权利。
Ethnopharmacological relevance: Herbal medicine value chains have generally been overlooked compared with food commodities. Not surprisingly, revenue generation tends to be weighted towards the end of the chain and consequently the farmers and producers are the lowest paid beneficiaries. Value chains have an impact both on the livelihood of producers and on the composition and quality of products commonly sold locally and globally and consequently on the consumers. In order to understand the impact of value chains on the composition of products, we studied the production conditions for turmeric (Curcuma longa) and the metabolomic composition of products derived from it. We aimed at integrating these two components in order to gain a better understanding of the effect of different value chains on the livelihoods of some producers.Materials and methods: This interdisciplinary project uses a mixed methods approach. Case studies were undertaken on two separate sites in India. Data was initially gathered on herbal medicine value chains by means of semi-structured interviews and non-participant observations. Samples were collected from locations in India, Europe and the USA and analysed using H-1 NMR spectroscopy coupled with multivariate analysis software and with high performance thin layer chromatography (HPTLC).Results: We investigate medicinal plant value chains and interpret the impact different value chains have on some aspects of the livelihoods of producers in India and, for the first time, analytically assess the chemical variability and quality implications that different value chains may have on the products available to end users in Europe. There are benefits to farmers that belonged to an integrated chain and the resulting products were subject to a higher standard of processing and storage. By using analytical methods, including HPTLC and H-1 NMR spectroscopy, it has been possible to correlate some variations in product composition for selected producers and identify strengths and weaknesses of some types of value chains. The two analytical techniques provide different and complementary data and together they can be used to effectively differentiate between a wide variety of crude drug powders and herbal medicinal products.Conclusions: This project demonstrates that there is a need to study the links between producers and consumers of commodities produced in so-called 'provider countries' and that metabolomics offer a novel way of assessing the chemical variability along a value chain. This also has implications for understanding the impact this has on the livelihood of those along the value chain. (C) 2014 The Authors. Published by Elsevier Ireland Ltd. All rights reserved.
