Antidiabetic, anti-inflammatory and cytotoxic potential of Theobroma cacao Linn. husk aqueous extracts

Abstract

Background Theobroma cacao Linn. husks are considered agricultural wastes, but studies show that they exhibit natural compounds that may be used in alternative medicine. Hence, this study was conducted to determine the antidiabetic, anti-inflammatory, and cytotoxic potential of T. cacao husk aqueous extracts (TCE). Results A significantly higher glucose dialysis retardation index (GDRI) was shown by 10% TCE than the rest of the concentrations (1%, 3%, 5%, 7%) (P<0.05), and its activity is comparable with 5% Metformin (positive control) after 30 min, 60 min, 120 min and 180 min of incubation. The 7% TCE also showed significantly higher GDRI than the 5%, 3%, and 1% concentrations (P<0.05), and its activity is comparable with 5% Metformin after 60 min and 180 min of incubation. Moreover, 10% TCE exhibited a significantly higher glucose uptake percentage than the rest of the samples (P<0.05) and has activity comparable with 5% Metformin. The anti-inflammatory assay showed a significantly higher inhibition rate of 10% TCE than the rest of the concentrations (P<0.05), and its activity is comparable with 5% Diclofenac (positive control). The cytotoxicity assay showed that the percentage mortality of brine shrimps after 24 h of exposure to the different TCE samples is less than 50%. Conclusion This study concludes that T. cacao husk aqueous extract has potential antidiabetic and anti-inflammatory properties without being toxic to cells.

Computational and experimental pharmacology to decode the efficacy of Theobroma cacao L. against doxorubicin-induced organ toxicity in EAC-mediated solid tumor-induced mice

“…Theobroma cacao L. nibs (family Sterculiaceae), native to Central America, have been reported to contain multiple secondary metabolites (flavonoids, polyphenols, and alkaloids) and are also indicated for multiple pharmacological activities, viz ., anti-inflammatory, anti-cancer, cardioprotective, nephroprotective, and hepatoprotective, including anti-oxidant properties ( Zięba et al, 2019 ; Cura et al, 2021 ; Fanton et al, 2021 ; Sun et al, 2021 ). Due to these pharmacological properties, it can be hypothesized that nibs of Theobroma cacao may neutralize the doxorubicin-metabolite-mediated ROS system and have a protective effect on the heart, liver, and kidneys in the chemotherapy involving doxorubicin.…”

Comparative analysis of total flavonoid, total phenolic content, and antioxidant activity of Theobroma cacao Pod Husk extract and its derived fractions

“…Cacao pod husk is a byproduct of chocolate processing, and if not handled properly, it becomes an environmental waste. In recent decades, numerous studies have indicated that cacao pod husk possesses pharmacological capabilities as an anti-inflammatory [5], anticancer [6], antidiabetic, antioxidant, and antibacterial agent [7]. Karim et al [8] reported that the antioxidant activity of 80% ethanol extract ranged from 20.35 to 45.26 mg/mL.…”
