From the embryos of the seeds of Nelumbo nucifera, three bisbenzylisoquinoline alkaloids, nelumboferine and nelumborines A and B, were isolated along with four known compounds, neferine, liensinine, isoliensinine and anisic acid. The structures of the new alkaloids were determined mainly by spectroscopic methods.

Purpose Of Review: This review explores the mechanistic pathways and clinical implications of phytochemicals in obesity management, addressing the global health crisis of obesity and the pressing need for effective, natural strategies to combat this epidemic.
Recent Findings: Phytochemicals demonstrate significant potential in obesity control through various molecular mechanisms. These include the modulation of adipogenesis, regulation of lipid metabolism, enhancement of energy expenditure, and suppression of appetite.

This study aims to investigate the mechanism of berberine in regulating the metabolism network via clock-controlled genes represented by brain and muscle arnt-like 1(BMAL1) to ameliorate insulin resistance(IR) of hepatocytes in vitro. The HepG2 cell model of dexamethasone-induced IR(IR-HepG2) was established and treated with 5, 10, and 20 μmol·L~(-1) berberine, respectively, for 24 h. The glucose oxidase method and cell counting kit-8(CCK-8) assay were employed to measure extracellular glucose concentration and cell viability, respectively.

Berberine (BBR), an isoquinoline alkaloid abundant in Coptis chinensis, exhibits anti-tumor and hypoglycemic properties. The regulation of tumor cell homeostasis and metabolism is greatly influenced by Hypoxia-inducible factor-1α (HIF-1α). This research aims to elucidate whether BBR inhibits the progression of hepatocellular carcinoma (HCC) by modulating HIF-1α expression.

: We assessed the influence of long-term injection of magnoflorine (MAG) on memory acquisition in mice for the first time. : This isoquinoline alkaloid that belongs to the aporphines was isolated from the roots of by centrifugal partition chromatography (CPC) using a biphasic solvent system composed of chloroform: methanol: water in the ratio 4:3:3 (//) with 20 mM of hydrochloric acid and triethylamine, within 64 min. : Our results indicated that long-term injection of MAG 20 mg/kg dose improve the long-term memory acquisition in mice that were evaluated in the passive avoidance (PA) test with no toxicity records.

The similar structures of natural compounds and the absence of NMR data for commercial products raise the risk of misidentification. This work reports a case in which purchased samples labeled as "berbamine" from 14 suppliers are oxyacanthine (). The NMR data of all purchased samples were consistent.
