Published: December 2003

A new apigeninglycoside, apigenin 6-C-galactosyl-6"-O-beta-galactopyranoside (1), isoorientin, and a mixture of orientin and isovitexin were isolated from leaves of Cecropia lyratiloba by high-speed countercurrent chromatography using a solvent system containing ethyl acetate, butanol, methanol and water. The structural elucidation of 1 was based on NMR spectroscopy.

is a lesser-known plant species belonging to the genus that grows in Kazakhstan. The aim of this study was to characterize the composition of the ethanolic, water, and hydroethanolic extracts from the aerial parts of by HPLC-ESI-QTOF-MS/MS to isolate the major compound isoquercitrin by HSCCC (High-Speed Counter-Current Chromatography) and to determine the cytotoxicity and anti-inflammatory potential of the extracts produced with this plant. Fingerprinting of the analyzed extracts showed the presence of a multitude of metabolites comprising polyphenols, organic acids, and coumarins, and only trace quantities of cardiac glycosides in the analyzed samples.

Natural products play a vital role in human health because people find that they can reduce the incidence of many diseases, such as cancer and cardiovascular diseases. Therefore, researchers have developed many effective techniques for screening and separating active compounds from natural products. High-speed countercurrent chromatography is a unique unsupported liquid-liquid chromatography technology that has been widely used in the separation of natural products.

In this work, different injection modes (single injection, overlapping injection, and continuous injection) of countercurrent chromatography were used and compared for the isolation and purification of glabridin from the crude extract of Glycyrrhiza glabra. The two-phase solvent system consisting of n-hexane/ethyl acetate/methanol/water (5:4:5:4, v/v) was employed as stationary and mobile phases. Compared with single injection mode, both overlapping injection and continuous injection modes exhibited higher separation efficiency at the same sample loading capacity.

Article Synopsis
  • The text discusses the isolation of two cytotoxic compounds, aurelianolides A and B, from a plant in the Solanaceae family, which shows potential as anticancer drugs.
  • Traditional methods for obtaining these compounds are costly and time-consuming, prompting a study to explore a more efficient technique using high-speed countercurrent chromatography (HSCCC).
  • The study achieved a successful separation of the withanolides in a single step, resulting in high-purity yields of aurelianolides A and B, significantly improving the process compared to classical methods.

Article Synopsis
  • The study used Novozyme 435 lipase to perform a biocatalytic transesterification reaction on esculin, aimed at increasing its hydrophobicity and improving solubility for commercial use.
  • The reaction occurred at 60 °C and produced two main products: a monoacylated and a diacylated form of esculin, with the diacylated form being the dominant product at a conversion rate of 53.55%.
  • Both products were purified using high-speed counter-current chromatography and characterized by NMR, demonstrating a fast and efficient method for enhancing the practical applications of esculin through the creation of acetylated derivatives.
