Other claims from this paper (9)
- Observation Total seed tocochromanol content across grapevine species ranged from 4.9 to 24.4 mg per 100 g dry weight.
- Observation α-tocotrienol was generally the main seed tocochromanol in Ampelocissus, Ampelopsis and Parthenocissus.
- Observation γ-tocotrienol preferentially accumulated in Cyphostemma seeds.
- Observation Vitis species contained similar amounts of α- and γ-tocotrienol.
- Observation Leea contained either α-tocotrienol alone or both main tocotrienols.
- Method / resource Ultrasound-assisted ethanol extraction recovered 92–98% of tocotrienols relative to saponification.
- Method / resource Ultrasound-assisted ethanol extraction recovered 62–86% of tocopherols relative to saponification.
- Method / resource The simplified extraction protocol was suitable for all studied Vitaceae species.
- Observation Multivariate analyses grouped species into α- and γ-tocotrienol-dominated groups.
