Mini Review: The Strategic Approach of Saponin to Reducing Methane Emissions.

Mshary, Ghasaq Sami; Castillo, Cristina; Hernandez, Joaquin; Muiño, Rodrigo

Ruminant production is facing a critical period within global agriculture due to unique digestive systems allowing them to utilize low-quality fibre-rich feed, producing the potent greenhouse gas methane (CH4) as a by-product. Methane is eliminated from the atmosphere by eructation. Saponins are secondary metabolites in plant seeds, leaves, bark, and roots. Some saponins were found from legumes and microbial populations, including Quillaja saponaria, Yucca schidigera, Camellia sinensis and Samanea saman. Saponin consists of a lipophilic triterpene or steroid aglycone attached to one or more hydrophilic sugar moieties. Their structural variety has appeared in their chemical and biological properties. Numerous pharmacological aspects of saponin include antifungal, antiprotozoal, antimicrobial, and anti-methanogen effects. More factors are related to the rumen microbe’s power to mitigate the antiprotozoal activity of saponins, such as breeds of animals and the environment. Tannin and saponin having plant species, such as alfalfa are widely utilized because of their beneficial matter and clearly can decrease methane production. The membrane-disrupting action of saponins illustrates their harmful influence on protozoa and the formation of complexes with sterols found in the protozoal cell wall, thereby causing cell lysis. This review aims to understand saponin structural features and focus on the prospect of being a useful resource for researchers in using saponin extract as a bioactive compound in ruminant diets to mitigate greenhouse gas emissions.
