Nutritional evaluation of twenty-four disease and pest resistance tomato varieties
Tomato, a fruit vegetable, is widely used in many dish components such as soup, stew/sauce, salad, and juice with many benefits. Even though annual and perishable, tomatoes are required yearly for use. Tomato production thus serves as a livelihood and food security activity across the country with different varieties. Some of these varieties, however, do not meet production criteria and consumer preferences. As such,...

Evaluation of catechin, lupeol, and betulinic acid as markers for the chromatographic quality Control of Albizia coriaria raw materials; an experimental study
Albizia coriaria stembark is among the most common raw materials used to manufacture herbal products in Uganda. While the plant material is sourced from the wild, there are neither monographs nor chemical analytical methods for its standardisation. In addition, good cultivation, harvesting, and manufacturing practices are not mandatory. This leads to inconsistent quality of raw materials and products. This work...
