本文报道了用传统方法和微波技术从越南北方不同产地的姜黄根中提取姜黄素的研究结果。该方法简单、经济、无毒、提取效率高，可从姜黄根中提取姜黄素类化合物。结合X射线粉末衍射和高效液相色谱/质谱的拉曼振动光谱的详细结果允许在所应用的制造技术的条件下对所接收的每批姜黄素结晶粉末样品进行评估。文中还介绍了样品的吸收光谱和荧光光谱。本文将提供的信息：吸收光谱和荧光光谱的样品;应用技术的实验研究新的成果，以姜黄根茎的姜黄素的大规模生产;制造的样品和市场上的姜黄素产品的比较研究结果-姜黄素粉末样品中共存的结晶相的复杂性。我们注意到，可以使用姜黄素分子中ν C=O振动的~959 cm−1处的振动线特征，以及ν C=O和ν C=C振动的~1625 cm−1线特征，对天然来源的姜黄素晶体粉末样品进行初步质量评估。这些新的光谱数据将有助于越南天然姜黄素的详细信息，为越南天然姜黄素粉末和纳米姜黄素的研究目的和应用提供服务，并成为制药，化妆品或功能性食品行业的初始材料。
In this report, we present the research results on using the conventional method and microwave technology to extract curcuminoid from turmeric roots originated in different regions of Northern Vietnam. This method is simple, yet economical, non-toxic and still able to achieve high extraction performance to get curcuminoid from turmeric roots. The detailed results on the Raman vibration spectra combined with X-ray powder diffraction and high-performance liquid chromatography/mass spectrometry allowed the evaluation of each batch of curcumin crystalline powder sample received, under the conditions of applied fabrication technology. Also, the absorption and fluorescence spectroscopies of the samples are presented in the paper. The information to be presented in this paper: absorption and fluorescence spectroscopies of the samples; new experimental study results on applied technology to mass-produce curcumin from turmeric rhizomes; comparative study results between fabricated samples and marketing curcumin products—to state the complexity of co-existing crystalline phase in curcumin powder samples. We noticed that, it is possible to use the vibration line at ~959 cm−1—characteristic of the ν C=O vibration, and the ~1625 cm−1 line—characteristic of the ν C=O and ν C=C vibration in curcumin molecules, for preliminary quality assessment of naturally originated curcumin crystalline powder samples. Data on these new optical spectra will contribute to the bringing of detailed information on natural curcumin in Vietnam, serving research purposes and applications of natural curcumin powder and nanocurcumin in Vietnam, as well as being initial materials for the pharmaceutical, cosmetics or functional food industries.
