A new saponin, cristatain (1), together with four other saponins, celosin A (2), celosin B (3), celosin C (4) and celosin D (5) were isolated from the seeds of Celosia cristata L. (Amaranthaceae). Their structures were established by chemical and spectroscopic analyses. For the first time, the saponins were found in C. cristata L. In addition, compound 1 exhibited significant hepatoprotective effect on carbon tetrachloride (CCl(4))- and N,N-dimethylformamide (DMF)-induced hepatotoxicity in mice, which were evidenced by significant decreases in the values of asparate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) of serum and histopathological examinations compared to controls.

Article Synopsis
- Celosia Semen (CS) is a traditional Chinese medicine known for promoting liver health and improving vision, primarily due to its active components, particularly triterpenoid saponins like Celosin I, which are being studied for their effects on non-alcoholic fatty liver disease (NAFLD).
- The study aims to explore the therapeutic effects of total saponins from CS (TSCS) and Celosin I (CI) on NAFLD, using a combination of in vitro and in vivo approaches to understand their molecular mechanisms and health benefits.
- Results showed that TSCS and CI significantly reduced lipid accumulation and liver injury caused by a high-fat diet, improved lipid metabolism by correcting dysregulation linked to NAFL

Although natural products (NPs) from ethnomedical plants have played a vital role in modern drug discovery, separation and purification of bioactive compounds from plant extract is still challenging. In this study, a dereplication strategy using HPLC-QTOF-MS was employed to rapidly discover and highly targeted isolate the novel hepatoprotective triterpenoid saponins from the methanol extract of Celosiae Semen. Firstly, four known saponins, i.

Three new oleanane-type triterpenoid saponins named celosins H, I, and J were isolated from the seeds of Celosia argentea L. Their structures were characterized as 3-O-β-D-xylopyranosyl-(1 → 3)-β-D-glucuronopyranosyl-polygalagenin 28-O-β-D-glucopyranosyl ester, 3-O-β-D-glucuronopyranosyl-medicagenic acid 28-O-β-D-xylcopyranosyl-(1 → 4)-α-L-rhamnopyranosyl-(1 → 2)-β-D-fucopyranosyl ester, and 3-O-β-D-glucuronopyranosyl-medicagenic acid 28-O-α-L-arabinopyranosyl-(1 → 3)-[β-D-xylcopyranosyl-(1 → 4)]-α-L-rhamnopyranosyl-(1 → 2)-β-D-fucopyranosyl ester by NMR, MS, and chemical evidences, respectively. In our opinion, celosins H-J could be used as chemical markers for the quality control of C.
