Steam distilled carrot seed oil typically contains significant amounts of the sesquiterpene alcohol carotol (<67%) and the monoterpenoid ester geranyl acetate (<25%) (Figure 3), with highly variable amounts of the monoterpenoids alpha-pinene (2-25%), sabinene (<32%) and linalool (<6%), and of the sesquiterpenoids P-bisabolene (<16%) and daucol (<10%) (13,14,15,16) Three flavones,
luteolin,
luteolin 3'-O-P-D-glucopyranoside and
luteolin 4'-O-P-D-glucopyranoside have been isolated from a methanol extract of carrot seed.
Fraction EaII was found to contain coumestan wedelolactone and demethylwedelolactone as major components with apigenin,
luteolin, 4-hydroxybenzoic acid, and protocatechuic acid as minor constituents [44].
Among the flavonoids,
luteolin and apigenin are the main flavones with better pharmacological activities [4].
TEHRAN (FNA)- Celery, artichokes, and herbs, especially Mexican oregano, all contain apigenin and
luteolin, flavonoids that kill human pancreatic cancer cells in the lab by inhibiting an important enzyme, according to two new University of Illinois studies.
Washington, August 16 ( ANI ): Celery, artichokes, and herbs, Mexican oregano, have apigenin and
luteolin, flavonoids in them which help kill human pancreatic cancer cells by inhibiting an important enzyme, according to two studies.
DSM's studies reveal that high levels of chlorogenic acid and
luteolin derivatives provide Leontopodium alpinum helvetia with its unique capacity to protect and regenerate the skin's natural barrier.
The highest oxidation inhibition percentage for radical [DPPH.sup.*] was observed in Caribe extract, coinciding with the highest levels of gallic acid, chlorogenic acid, epicateehin, rutin,
luteolin, resveratrol (r [greater than or equal to] 0.85) and ascorbic acid.
Perilla contains rosmarinic acid and
luteolin, which are believed to be the active constituents.
The flavonoid compounds found in the leaves are quercetin, phloretin, catechins,
luteolin and kaempferol.

Luteolin, found in carrots, celery, olives, and peppers, has been found to reduce the aggressiveness of skin cancer cells and stop their growth.
The most known and well-studied flavones are apigenin and
luteolin. Flavones are found in vegetables and fruits like onions, parsley, wheat sprouts, tea, oranges, broccoli, celery, carrots, parsley, onion, cabbages, pepper, apple, chamomile, and some spices (26, 27).
These include punicalagin,
luteolin, ellagitannins, and assorted polyphenols that can impede many steps involved in the formation, growth, and spread of cancer.
