olive leaf extracts hydroxytyrosol cas 10597-60-1

plant source of olive leaf extract:

the olive tree, olea europaea, is an evergreen tree or shrub native to the mediterranean, asia, and africa. it is short and squat, and rarely exceeds 8–15 m (26–49 ft) in height. 'pisciottana', a unique variety comprising 40,000 trees found only in the area around pisciotta in the campania region of southern italy often exceeds this, with correspondingly large trunk diameters. the silvery green leaves are oblong, measuring 4–10 cm (1.6–3.9 in) long and 1–3 cm (0.39–1.18 in) wide. the trunk is typically gnarled and twisted.
the small, white, feathery flowers, with ten-cleft calyx and corolla, two stamens, and bifid stigma, are borne generally on the previous year's wood, in racemes springing from the axils of the leaves.
the fruit is a small drupe 1–2.5 cm (0.39–0.98 in) long, thinner-fleshed and smaller in wild plants than in orchard cultivars. olives are harvested in the green to purple stage. canned black olives have often been artificially blackened (see below on processing) and may contain the chemical ferrous gluconate to improve the appearance. olea europaea contains a seed commonly referred to in american english as a pit or a rock, and in british english as a stone.

product data of olive leaf extract with hydroxytyrosol:

active ingredient hydroxytyrosol info of olive leaf extract:

hydroxytyrosol is a phenylethanoid, a type of phenolic phytochemical with antioxidant properties in vitro. in nature, hydroxytyrosol is found in olive leaf and olive oil, in the form of its elenolic acid ester oleuropein and, especially after degradation, in its plain form.

hydroxytyrosol is the superstar of antioxidants - the most powerful discovered to date! it has an orac value (oxygen radical absorbance capacity - its ability to absorb cell-damaging free radicals) of 68,576 - which is considered to be 15 times higher than green tea and 3 times higher than coq10.

it is not well-known yet because its discovery, and extensive studies of its properties, are so recent. yet hydroxytyrosol is already being recognized by scientists for its powerful anti-inflammatory, antibacterial, antioxidant and cardioprotective properties.
