“…The limonoids are chiefly present in seeds of citrus species such as Citrus sudachi (Nakagawa, Duan, & Takaishi, 2001), C. reticulate (Khalil, Maatooq, & El Sayed, 2003) in high concentration. However, peels (Citrus unshiu) have also been reported to possess these in significant amounts (Sawabe et al, 1999). On an average, orange, grapefruits and lemon juice contain 320, 190 and 80 mg/ml of limonoid glucosides, respectively (Miller, Porter, Binnie, Guo, & Hasegawa, 2004).…”
