Abstract This study investigated the nutrient composition of Ocimum basilicum L. (sweet basil) cultivated in a household hydroponic greenhouse module, with emphasis on tissue analysis of selected micronutrients and vitamin A. Basil plants were grown in both tube and raft cultures over a 37-day cropping cycle. Freshly harvested leaves were subjected to laboratory analysis to determine concentrations of iron (Fe), zinc (Zn), and vitamin A, which are commonly deficient in the Filipino diet. Results showed that iron content in basil leaves from both tube (5.70 mg) and raft (9.70 mg) cultures exceeded the standard reference value of 3.17 mg, demonstrating enhanced accumulation despite undetected iron in the nutrient solution. In contrast, zinc concentrations were lower than the reference standard (0.81 mg), with values of 0.30 mg and 0.50 mg from tube and raft cultures, respectively, suggesting competitive interactions with iron uptake. Vitamin A levels, determined from beta-carotene analysis, were 6,635 IU in tube culture and 5,175 IU in raft culture, compared to the standard 5,275 IU. The elevated vitamin A content in tube-grown basil is attributed to reduced sunlight exposure and increased carotenoid accumulation. These findings underscore the nutritional potential of hydroponically grown basil, particularly as a rich source of iron and vitamin A, while highlighting the need for nutrient solution adjustments to improve zinc uptake.
