“…The AGO's oil yield in this experiment was higher than the Angola x Lame hybrid reported by Adon et al (2021), which fell from 20.8% to 21.9%. Nevertheless, the vitamin E of AGO was lower when compared to the findings of Karim et al (2021) (2021) showed that the total level of vitamin E in African oil palms ranged from 200 ppm to 1500 ppm. Moreover, their study highlighted a significant link (P = 0.0062) between the origin of the African palm and the levels of tocopherols and tocotrienols.…”

“…This breeding process involves assessing materials with diverse genetic backgrounds, including African oil palm originating from Angola (Adon et al, 2021), Cameroon (Mathieu et al, (2016)) and American oil palm E. oleifera (Mozzon et al, 2020). To expedite and enhance the selection accuracy, the breeders employ molecular approaches and develop the molecular marker for vitamin E traits (Dou et al, 2021;Karim et al, 2021). These efforts aim to unlock the full potential of tocotrienols and vitamin E from oil palm for various medicinal uses…”

Crude palm oil (CPO) contains various forms of vitamin E, including tocopherol, tocotrienol and a small amount of tocomonoenol, collectively known as tocols. Among these, tocotrienol is dominant in CPO, constituting approximately 70% of the total tocols; unlike tocopherol, which is known for its anti-ageing properties, tocotrienol exhibits potent antioxidant activities, 60 times stronger than tocopherol. Tocotrienol is recognized for its diverse health benefits as a neuroprotective, nephroprotective, anti-cancer, anti-cholesterol, anti-diabetic, and anti-inflammatory agent. Consequently, tocotrienol holds immense potential for pharmaceutical and nutraceutical applications. The exploration of oil palm materials planted in Kebun Adolina PTPN IV, North Sumatera, has been conducted since 2020, encompassing diverse genetic backgrounds, including commercial palm DxP varieties, an interspecific hybrid of Elaeis oleifera x Elaeis guineensis, wild-type palm materials originated from Angola and Cameroon, and palm clones of commercial DxP varieties. The analysis revealed a wide range of total vitamin E (tocol) content, ranging from 310.78 ppm to 1681.45 ppm. Among the genotypes studied, AD14S311 and AD14S2220 emerged as promising candidates for ortets to develop oil palm varieties with high content, especially tocotrienol. These genotypes demonstrated a high oil extraction rate (OER) and a total vitamin E level above 1000 ppm. These findings remade the potential genotypes as genetic resources for breeding programs in developing oil palm varieties enriched with tocotrienol and fulfilled the commercial value.
