AbstractPouteria caimito is a commercially valuable tropical fruit tree and has medicinal effects in Brazilian folklore. In this thesis, thirteen compounds were isolated for the first time from the fruit of P. caimito by ethanol extraction and various chromatographic column chromatography methods. The thirteen compounds were identified by NMR, HR-ESI-MS and various physicochemical data to contain nine triterpenoids. The results of activity screening experiments showed that compounds 2, 3 and 5 exhibited anti-inflammatory activity, while most of the triterpenoids exhibited anti-RSV, and anti-HSV activity to varying degrees. Based on these results, the content of compound 5 was determined due to its good pharmacological activity to be 13.3250 mg/kg in the fresh fruit. This study scientifically demonstrated the health benefits of consuming P. caimito fruits and also provided new ideas for further development and utilization of P. caimito. It not only has good potential as an anti-inflammatory or antiviral functional food but also can be considered a natural source of triterpenoids.

This study was aimed to investigate the effect of heat stress and seasons on diurnal body temperature, milk yield, and physicochemical properties of dromedary camel in southeastern rangelands Ethiopia. Twenty lactating camels with 2–3 months postmortem and 3–4 parities were selected for evaluation of milk yield, physicochemical properties, and body temperature measurements. The current finding shows diurnal body temperature was significantly higher in hot weather conditions (dry season). Temperature-humidity index (THImax) showed a strong positive correlation to rectal body temperatures (r = 0.72) and daily milk yield (r = 0.6) of a camel. The mean daily milk yield observed in this study was 6.02, 4.99, 2.38, and 2.57 Liters (L) during autumn, spring, summer, and winter, respectively, and showed higher (P 0.05) across the seasons. The body temperature, milk physicochemical properties, and yield of dromedary camels were varied (p
