“…Recently, various researchers have successfully applied DL in herbal medicine to identify specific properties of herbal materials or to detect variations in the material due to variation in environmental growth conditions [22], different processing methods [23,24] and determination of authenticity [25]. Differences detected by DL in herbal materials are also reflected by their chemical profiling [24,26] as well as therapeutic activities [27].…”

Background: Investigation of aged Chinese herbal materials will help us to understand their use and sources in ancient time and broaden the historical perspective of Chinese material medica. To reach this aim, the basic understanding of aged herbal materials, including physical and chemical characters, is of great importance. Delayed luminescence (DL) technique was developed as a rapid, direct, systemic, objective and sample loss-free tool to characterize the properties of Chinese herbal materials. In this study, we measured DL values in aged Chinese herbal materials that were transported from Asia to Europe during the 20th century and stored in Naturalis Biodiversity Center and the Utrecht University museum, and compared these with modern material of the same species. Methods: A hyperbolic function was used to extract four properties from the DL curves of Chinese herbal material from 1900, the 1950s and recently harvested products. Statistical tools, including the Student's t test, One-way analysis of variance and Principal Component Analysis, were used to differentiate the DL properties of aged and contemporary collections of Glycyrrhiza spp. Curcuma aromatica Salisb., Zingiber officinale Roscoe, Alpinia officinarum Hance and Acorus calamus L. Results: Our results showed that DL properties were significantly different between historical and contemporary Chinese herbal materials. Changes in DL values were species-dependent: the effects of storage time of DL properties were specific for each species. These outcomes help us not only in the identification of historical Chinese medicine products but also provides valuable data of the effect of storage time on herbal materials. Conclusion: The simple, direct, rapid, and inexpensive measurements offered by DL provide a novel tool to assess the taxonomic identity of Chinese and other herbal materials and assess the differences in chemical properties with increasing storage time. Our results contribute to the further development of novel digital tools for the quality control of herbal materials.

“…A series of studies has shown that rhubarb can be used to treat ischemic stroke, and has anti‐inflammatory, anti‐cancer and anti‐hepatitis B virus (HBV) effects, among others. The main compounds in rhubarb include rhein, emodin, aloe‐emodin, physcion, chrysophanol, sennoside A, sennoside B, gallic acid, and catechin . Of these, the five anthraquinone compounds are recommended by the Chinese Pharmacopoeia (2015) as the quality indexes, and the two sennosides are similarly recommended by the Japanese Pharmacopoeia .…”

Effects of different nitrogen fertilizer levels on growth and active compounds of rhubarb from Qinghai plateau

Background Rheum tanguticum Maxim. ex Balf is one of the plants generically known as rhubarb, a culinary vegetable that has long been used as a herbal remedy both in China and Europe. Increasing demand for rhubarb has triggered the overexploitation of Rh. tanguticum. Cultivation is therefore necessary for quality control and protection of wild resources. Nitrogen fertilizer plays an important role in cultivation. This study aimed to explore how nitrogen fertilizer affects the growth and quality of rhubarb on the Qinghai‐Tibetan plateau. Results Nitrogen fertilizer promoted growth but had no significant influence on the active compounds of Rh. tanguticum. Generally, the N2 (150 kg ha−1) and N3 (225 kg ha−1) levels showed the most improved growth indexes, with no significant differences between them. The growth index and the amounts of eight of the nine studied active compounds in Rh. tanguticum increased from each year to the next and differed among growth stages. The contents of the active compounds were higher at the green stage and lower at the growth stage, which was opposite to the seasonal trends in root dry matter ratio. Gallic acid levels decreased with the growth of the plant. Conclusion The N2 level (150 kg ha−1) was the recommended nitrogen fertilizer level in this study. It was revealed that seasonal changes rather than nitrogen fertilizer influenced active compounds in the root of Rh. tanguticum. © 2018 Society of Chemical Industry

Rhubarb is a widely used Traditional Chinese Medicine in treating various diseases for thousands of years, and polysaccharide is one of the bioactive constituents in this herb. However, study of the polysaccharide is very limited, especially structural characterization. In the present study, a polysaccharide from Rheum palmatum L. (PR) was isolated and puried. Based on UV, IR, GC, GC-MS, 1H NMR and 13C NMR analyses, the structure of PR was characterized. Its molecular weight was measured to be 1.21 × 10 4 Da. The results of PR structural analysis showed that four 1→4 galactose were linked with one 1→ 3, 6 galactose and one 1→6 glucose, and each repeating unit had a branched chain consisting of a α-1→ xylose, which was linked with the C-6 of galactose backbone chain.
