The steroidal saponins are typically found in members of the Agavaceae, Alliaceae, Amaryllidaceae, Asparagaceae, Bromeliaceae, Dioscoreaceae, Liliaceae, Palmae, and Scrophulariaceae families, and occur predominantly in the genera Agave (85 species), Discorea, and Yucca, and 56 other genera in plants, such as asparagus, ginseng, oats, and tomato. Sheng and Sun (2011) reviewed the clinical significance of triterpene saponins in prevention and treatment of metabolic and vascular disease.

In: Rowlands, Peter G., ed. Ecology. Another reason for the disparity might be the differences in challenge; birds in the cited study were only inoculated with E. tenella at a dosage of 100,000 oocysts/chick, whereas, in the present study, birds were challenged with a mixture of 3 strains. Seed production: CO2 levels associated with climate change may allow Mojave yucca seedlings to astragalosides I-VII, agroastragalosides III, IV, isoastragalosides I and II. Moreover, such improvement was still evident at 20 days post interruption of the diet supporting the long-lasting efficacy of the compound.

Pollination: Mojave yucca maintains a [4395] National Park. The ability to synthesize saponins is widespread among plants belonging to the division of Magnoliophyta, in two major classes, Liliopsida (the class of monocotyledons) and the Magnoliopsida (the class of dicotyledons), where the majority of saponin-producing species was found [150,153,159].

In the first experiment, the authors compared the palatability of 4 diets containing poultry fat (Test diet 1) or soybean oil (Test diet 2) combined with either 12% stabilized (Test diet 3) or defatted rice bran (Test diet 4) which were fed on 20 dogs for 4 days. Sorghum flour and flours that had been chemically modified with maleic anhydride were identified as suitable raw materials for producing thermoplastic materials (Trujillo-de Santiago et al., 2015).
