or Maca is widely cultivated as a health care food supplement due to its nutritional and medicinal properties. Although there are a few in-depth studies evaluating Maca antihypertensive effects, the correlations between the chemical constituents and bioactivity of the plant have not been studied before. Thus, the roots were extracted using different solvents (aqueous, methanol, 50% methanol, and methylene chloride) and investigated for their antihypertensive and antioxidant activities through several assays.

Chemical investigation of the aerial parts of ethanol extract (AEEE) showed high concentrations of polyphenol and flavonoid content, with notable antioxidant activity. Undescribed acylated diglucoside flavonol myricetin 3----(6″--galloyl glucopyranoside) 7----glucopyranoside (MGGG) was isolated from the aerial parts of AEEE, along with four known polyphenols that had not been characterized previously from AEEE. The inhibitory effects of MGGG, AEEE, and all compounds against -amylase, pancreatic lipase and -glucosidase were assessed.

High consumption of industrialized food with high fat content is generally associated with insulin resistance, which in turn causes memory impairment and cognitive decline. Nicotinamide and ascorbic acid are among the promising neuroprotective molecules; however, an appreciable therapeutic activity necessitates the administration of a large dose of either. Therefore, the study aimed to assess if loading them in chitosan nanoparticles in doses 5-10 times lower than the unencapsulated forms would achieve comparable therapeutic results.

The novel strain of human coronavirus, emerged in December 2019, which has been designated as SARS-CoV-2, causes a severe acute respiratory syndrome. Since then, it has arisen as a serious threat to the world public health. Since no approved vaccines or drugs has been found to efficiently stop the virulent spread of the virus, progressive inquiries targeting these viruses are urgently needed, especially those from plant sources.

Aims: Non-alcoholic fatty liver disease (NAFLD) caused by consumption of high levels of fat and sugars (HFHS) in diet is considered one of the most dangerous medical complications among children and adolescents. Nicotinamide is among the promising candidates in ameliorating HFHS diet-induced NAFLD, but its use is limited by the possibility of prompting hepatotoxicity in high doses. Ascorbic acid is another promising candidate, however its use as a hepatoprotective agent is limited by its chemical instability.

The current study aimed to investigate the anti-epileptic potential of the ethanol extract and its different fractions from the plant, . The results revealed that the aqueous fraction with the latest onset of myoclonic convulsions (1095 ± 45**** s) was the most biologically active one. This was followed by LC-HR-MS-coupled metabolic profiling which led to dereplication of 8 compounds from that fraction.

Article Synopsis
  • The study identified bioactive compounds in the ethyl acetate fraction of plant aerial parts that exhibit local anesthetic properties.
  • Twelve compounds were separated from the most potent fraction, showing a mean onset time for anesthesia comparable to a standard anesthetic (tetracaine).
  • Molecular docking studies indicated that Rabdosiin and Apigenin-7-O-rutinoside are the key compounds for local anesthesia, likely blocking sodium ion channels to prevent pain sensation.

Both ethyl acetate and aqueous fractions of leaves exhibited noteworthy antioxidant and nephroprotective activities against carbon tetrachloride (CCl)-induced nephrotoxicity in rats, as evidenced by the remarkable improvements of renal serum biomarkers and histopathological features. Additionally, the ethyl acetate fraction displayed a prominent antitrypanosomal activity against ; consequently, the leaves were subjected to LC-HR-ESI-MS metabolomic profiling to discover the constituents that possibly underlie their bioactivities. Therefore, ten metabolites were characterized, mostly dominated by flavonoids.
