Dill (Anethum graveolens) is an annual or biennial herb. It grows
up to 90–120 cm tall and has slender branched stems, finely divided
leaves, small umbels (2–9 cm diameter) of yellow flowers,
and long spindle-shaped roots. In general, dill leaves (dill weeds)
and seeds (small fragrant fruits) are used as seasoning. The leaves
could be used in eggs, meats, salads, seafoods and soups; the seeds
could be used in bread, and flavouring pickles and soups. Dill
essential oil, extracted from both leaves and seeds, could also be
used in chewing gums, candies and pickles (Just, 2008; Tucker,
2008; Zohary & Hopf, 2000).
The plant is native in Southwest Asia and is cultivated in Europe,
India and the United States (Tucker, 2008). It is also successfully
cultivated in Taiwan. Literature demonstrates that dill leaf consumption
could lower the risk of cancer (Yang, Huang, Peng, & Li,
1996) and reduce the level of cholesterolaemia (Lanky, Schilcher,
Phillipson, & Loew, 1993). Moreover, dill leaf, seed and their essential
oil could provide good antioxidant activities (Delaquis, Stanich,
Girard, & Mazza, 2002; Kmiecik, Ge˛bezyn´ ski, & Jaworska, 2001;
Mohammad Al-Ismail & Aburjai, 2004; Singh, Maurya, Lampasona,
& de Catalan, 2005). Many reports indicate that plant flowers
have remarkable antioxidant activity (Elzaawely, Xuan, Koyama,
& Tawata, 2007; Ho, Hwang, Shen, & Lin, 2007; Kaur, Alam, Jabbar,
Javed, & Athar, 2006; Susanti et al., 2007). There is, however, no
thorough report on the antioxidant capacity of dill flower.
The antioxidant properties of ethanolic extract from the flower
of dill cultivated in Taiwan and its various fractions (n-hexane,
ethyl acetate and ethanol) were evaluated for 2,2-diphenyl-1-picrylhydrazyl
(DPPH) radical scavenging, Trolox equivalent antioxidant
capacity (TEAC), reducing power, and b-carotene bleaching
efficacies. Ethanolic extracts of dill leaf and seed were also used
for comparison in all assays. Antioxidant components in these extracts
were also determined.

Dill (Anethum graveolens) is 'n jaarlikse of tweejaarlikse plante. Dit groei
tot 90-120 cm hoog en het vertakte stamme slank, fyn verdeelde
blare, skerms Klein (2-9 cm in deursnee) van geel blomme,
en 'n lang spoelvormige Roots. In die algemeen, dille blare (dille onkruid)
is en Saad (Klein vrugte geurige) gebruik as geurmiddels. Die blare
kan gebruik word in eiers, vleis, slaaie, sop en Seafoods; die sade
kan gebruik word in brood, piekels en sop en Aromatiseren. Dille
Essential Oil, 'n uittreksel uit beide blare en sade, kan ook
gebruik word in kauwgom, lekkergoed en piekels (Net, in 2008; Tucker,
die 2008, Zohary & Hopf, die 2000).
Die plant is inheems in Suidwes-Asië en verbou in Europa. ,
Indië en die Verenigde State van Amerika (Tucker, in 2008). Dit is ook suksesvol
gekweek in Taiwan. Literatuur dui aan dat dille Leaf verbruik
die risiko van kanker (Yang, Huang, Peng, en Li, kan verlaag
1996) en die vermindering van die vlak van die bloed cholesterolgehalte (lenige, Schil,
Phillipson, & Loew, 1 993). Verder, dille Leaf, Saad en hul noodsaaklike
kon Olie goeie antioksidant aktiwiteit (Delaquis, Stanich, bied
Kmiecik, Ge˛bezyn 'Ski, & Jaworska, 2001;; Girard, & Mazza, die 2002
Mohammad Al-Ismail & Aburjai, die 2004; Singh. , Maurya, Lampasona,
& de Katalaans, 2005). Baie verslae dui daarop dat Plant blomme
het antioksidant Opvallend aktiwiteit (Elzaawely, Xuan, Koyama,
& Tawata 2007; Ho, Hwang, Shen, & Lin, 2007; Kaur, Alam, Jabbar,
Javed, & Athar, 2006; et al Susanti. 2007). Daar is egter geen
deeglike Verslag oor die antioksidant kapasiteit van dille Flower.
Die anti-oksidant eienskappe van etanoliese Uittreksel uit die Flower
van dille in Taiwan en sy verskillende breuke (N-heksaan, gekweek
Etielasetaat en etanol) is geëvalueer vir 2,2. -diphenyl-1-Picrylhydrazyl
(DPPH) radikale blaas, anti-oksidant Trolox Ekwivalente
kapasiteit (TEAC), die vermindering van B-karoteen bleek Power en
effektiwiteit. Etanoliese uittreksels van dille Leaf en Saad is ook gebruik
vir 'n vergelyking in alle toetse. Antioksidant komponente in hierdie uittreksels
is ook bepaal.
