| Type of fruit seed oil | Cultivar | Key finding | Reference |
|---|---|---|---|
| Apple | ‘Gale Gala’, ‘Starking’, ‘Honeycrisp’, ‘Fuji’, ‘Qinguan’, ‘Golden Delicious’, ‘Qinyang’ | ‘Honeycrisp’ exhibited higher antioxidant capacity | Xu et al. (2016) |
| Date | ‘Boufgous’, ‘Bousthammi’, ‘Majhoul’ | Higher FRAP (22.86 mmol TE/100 g DW) and ABTS radical scavenging capacity (8.02 (mmol TE/100 g DW) was manifested in oil from ‘Bousthammi’. ‘Boufgous'showed better DPPH radical scavenging capacity (0.17 g/L) | Bouhlali et al. (2015) |

| Fig | ‘White Adriatic’, ‘Bourjassote Noir’,C7A14, C11A21 | ‘White Adriatic’ and ‘Bourjassote Noir’ were reported the best in ABTS and DPPH radicals scavenging capacity | Hssaini et al. (2020) |
| Cactus pear | ‘Nepgen’, ‘Morado’, ‘Ofer’, ‘Gymno-Carpo’, ‘Meyers’, ‘Sicilian’, ‘Nudosa’, ‘Robusta’ | DPPH radical scavenging capacity varied among the cultivars | De Wit et al. (2017) |
| Grape | ‘Merlot’, ‘Syrah’, ‘Sangiovese’, ‘Muscat d’Alexandrie’, ‘Razagui’, ‘Razaki’, ‘Khamri’, ‘Marsaoui’, ‘Cargnan’ | ‘Carignan’ and ‘Muscat d’Alexandrie’ and were higher in DPPH radical scavenging capacity (IC50: 30.97 μg/g) and chelating ability (IC50: 8.96 μg/g) and Reducing power (IC50: 23.20 μg/g), respectively. | Harbeoui et al. (2017) |
| ‘Blatina’, ‘Cabernet’, ‘Merlot’, ‘Muscat Hamburg’, ‘Vranac’ | ‘Cabernet’ and ‘Muscat Hamburg’ showed the best and least antioxidant activity, respectively | Banjanin et al. (2019) | |
| ‘Barbera’, ‘Chardonnay’, ‘Muller Thurgau’, ‘Muscat’, ‘Nebbiolo’, ‘Pinot Noir’ | ‘Pinot Noir’ had better hydrophilic antioxidant activity (1.73 mmol Trolox/g), whilst ‘Barbera’ showed greater lipophilic antioxidant activity (8.2 mmol Trolox/g) | Mohamed et al. (2016) | |
| Pomegranate | ‘Tunisia soft’, ‘Taishanhong’, ‘Qingpiruanzi’ | Greater DPPH radical scavenging capacity and FRAP were shown by Tunisia soft’ and ‘Qingpiruanzi’, respectively | Peng (2019) |
| Lemon | ‘Feiminailao’, ‘Beijignningmeng’, ‘Pangdelusaningmeng’, ‘Limeng’, ‘Cuningmeng’ (CN) | Greater antioxidant capacities (DPPH radical scavenging capacity: 4.01%), (ABTS radical scavenging capacity:11.97 mM) and (FRAP: 3.40 mM) were exhibited by ‘Feiminailao’ | Xi et al. (2017) |
| Orange | ‘Hamli’, ‘Natal’, ‘Pera-rio’, ‘Valencia’ | Best DPPH radical scavenging capacity was exhibited by ‘Pera-rio’. | Jorge et al. (2016) |
| Passion | ‘Passiflora alata BRS Doce Mel’, ‘Passiflora alata BRS Mel do Cerrado’, ‘Passiflora edulis BRS Gigante Amarelo’, ‘Passiflora edulis BRS Sol do Cerrado’, ‘Passiflora tenuifila VI’, ‘Passiflora setacea BRS P'erola do Cerrado’ | ‘Passiflora setacea BRS P'erola do’ Cerrado also showed higher antioxidant activity. | De Santana et al. (2015) |
DPPH = 2, 2-diphenyl-1-picryl hydrazyl, FRAP = Ferric reducing antioxidant power, ABTS = 2, 2′-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid, TE = trolox equivalence.
