Rapid analysis of Momordicoside A in bitter melon by high performance liquid chromatography following solid phase extraction
Se Pu 2001 Mar;19(2):128-31.PMID:12541654doi
A rapid, simple and accurate method for the determination of Momordicoside A has been established using solid phase extraction (SPE) followed by high performance liquid chromatography (HPLC). Sample was processed by SPE on a Carb cartridge (3 mL/250 mg), and was then determined by HPLC on a C18 column (4.6 mm i.d. x 250 mm, 5 microns) with V(acetonitrile):V(methanol):V(50 mmol/L potassium dihydrogen phosphate buffer) = 25:20:60 as mobile phase (0.8 mL/min) and UV detection at 208 nm. The calibration curves were linear from 10 mg/L to 1,000 mg/L (r2 = 0.9992). The analytical method was shown to be highly reproducible, giving all of the relative standard deviations and relative mean errors less than 10% for both intra-day and inter-day determinations. The absolute recoveries were greater than 90%.
Anti-Inflammatory, Antidiabetic Properties and In Silico Modeling of Cucurbitane-Type Triterpene Glycosides from Fruits of an Indian Cultivar of Momordica charantia L
Molecules 2021 Feb 16;26(4):1038.PMID:33669312DOI:10.3390/molecules26041038.
Diabetes mellitus is a chronic disease and one of the fastest-growing health challenges of the last decades. Studies have shown that chronic low-grade inflammation and activation of the innate immune system are intimately involved in type 2 diabetes pathogenesis. Momordica charantia L. fruits are used in traditional medicine to manage diabetes. Herein, we report the purification of a new 23-O-β-d-allopyranosyl-5β,19-epoxycucurbitane-6,24-diene triterpene (charantoside XV, 6) along with 25ξ-isopropenylchole-5(6)-ene-3-O-β-d-glucopyranoside (1), karaviloside VI (2), karaviloside VIII (3), momordicoside L (4), Momordicoside A (5) and kuguaglycoside C (7) from an Indian cultivar of Momordica charantia. At 50 µM compounds, 2-6 differentially affected the expression of pro-inflammatory markers IL-6, TNF-α, and iNOS, and mitochondrial marker COX-2. Compounds tested for the inhibition of α-amylase and α-glucosidase enzymes at 0.87 mM and 1.33 mM, respectively. Compounds showed similar α-amylase inhibitory activity than acarbose (0.13 mM) of control (68.0-76.6%). Karaviloside VIII (56.5%) was the most active compound in the α-glucosidase assay, followed by karaviloside VI (40.3%), while momordicoside L (23.7%), A (33.5%), and charantoside XV (23.9%) were the least active compounds. To better understand the mode of binding of cucurbitane-triterpenes to these enzymes, in silico docking of the isolated compounds was evaluated with α-amylase and α-glucosidase.
[Study on chemical components of Momordica charantia]
Zhong Yao Cai 1998 Sep;21(9):458-9.PMID:12569838doi
The paper deals with the study of chemical constituents of the unmatured fruits of Chinese traditional medicine Momordica charantia L. which is usually used as green-stuff. There are two parts of the extracts obtained by ethanol precipitation, and four compounds obtained from the further isolation. They are identified as Vincine, Mycose, Momordicoside A and Momordicoside B.
