Ten new resin glycosides, controlins I-X (-), were isolated from the seeds of . Their structures were established by spectroscopic analysis as well as by chemical means. Compounds were identified as glycosidic acid methyl esters, considered as artifacts generated via transesterification with MeOH from natural resin glycosides. Compound is the first nonasaccharide resin glycoside, while compounds - are rare octasaccharide resin glycosides. Compounds , , and could inhibit the nitric oxide production in lipopolysaccharide-induced BV-2 cells, while compounds , , and exhibited neuroprotective effects on HO-induced damage in PC12 cells. Compounds and could dose-dependently alleviate the dyskinesia in the UM0001 strain of , a double transgenic line of Aβ and pro-aggregation tau, suggesting an anti-Alzheimer's activity, reported for resin glycosides for the first time.

The chemical components of Carthami Flos were investigated by using macroporous resin, silica gel column chromatography, reversed-phase octadecylsilane(ODS) column chromatography, Sephadex LH-20, and semi-preparative high-performance liquid chromatography(HPLC). The planar structures of the compounds were established based on their physicochemical properties and ultraviolet-visible(UV-Vis), infrared(IR), high-resolution electrospray ionization mass spectrometry(HR-ESI-MS), and nuclear magnetic resonance(NMR) spectroscopic technology. The absolute configurations were determined by comparing the calculated and experimental electronic circular dichroism(ECD).

Stevioside, a natural high-intensity sweetener, is widely employed across the food, pharmaceutical, and daily chemical industries due to its intense sweetness and health benefits. However, traditional extraction and purification processes for steviol glycosides from are plagued by low efficiency, high energy consumption, substantial environmental impact, and inconsistent product quality. This study systematically optimized the extraction, decolorization, decontamination, and desalting processes to overcome these challenges.

Dioscoreae hypoglaucae rhizome (DHR) is the dried rhizome of Dioscorea hypoglauca polibin, which is rich in steroidal saponins. The steroidal saponins present in DHR exhibit great pharmacological activities, particularly in inflammatory and anti-hyperuricemia effects. Despite steroidal saponins are recognized as primary bioactive components in DHR, the enrichment and purification processes of steroidal saponins is rare.
