Eucommia ulmoides Oliv. (EuO), also known as Duzhong, native to
China, is the only plant in the Eucommia genus of the Eucommiaceae
family. The bark and leaf of EuO have been used in traditional
Chinese medicine to treat lower back pain, knee pain, and the
liver, kidney, and spleen disorders. EuO extracts have
antihypertensive, antioxidative, and antigastric ulcer effects
(Metori et al., 1997; Deyama et al., 2001; Yang et al., 2003).
Water extracts of EuO leaves have been reported to have potent
antimutagenic effects (Nakamura et al., 1997; Lee et al., 2005; Luo
et al., 2009). EuO extracts have also been reported to enhance
collagen synthesis (Metori et al., 1997; Li et al., 2000a; 2000b;
Deyama et al., 2001). It is generally assumed that natural
substances in EuO give rise to these beneficial effects. The
chemical constituents of EuO leaves contain phenylpropanoid
compounds such as sitosterol, ursolic acid, and chlorogenic acid;
iridoids such as eucommiol, geniposidic acid, geniposide, and
aucubin; and flavonoids such as kaempferol and quercetin.
China has thousands of years of history to produce tea. E. ulmoides
leaves and E.ulmoides male flowers could be made into tea, and
traditional tea methods in china are general used to prepare these
types of products. Because they are rich in nutrients and bioactive
constituents, they are very good health care tea.
Eucommia is a kind of tree now native to China, with a fossil
record that shows a much wider distribution. The single living
species, Eucommia ulmoides, is near threatened in the wild, but is
widely cultivated in China for its bark, and is highly valued in
herbology such as Traditional Chinese medicine.It is one of the 50
fundamental herbs used in Chinese herbology.
Modern Eucommia trees grow to about 15 m tall. The leaves are
deciduous, arranged alternately, simple ovate with an acuminate
tip, 8–16 centimetres (3.1–6.3 in) long, and with a serrated
margin. If a leaf is torn across, strands of latex exuded from the
leaf veins solidify into rubber and hold the two parts of the leaf
together. It flowers from March to May with the flowers being
inconspicuous, small and greenish. The fruits ripen between June
and November and are a winged samara with one seed.
One-hundred twelve compounds of Eucommia ulmoides, including the
main active constituents, lignans and iridoids, have been isolated
and identified. In vitro and in vivo studies indicated that monomer
compounds and extracts from Eucommia ulmoides possess wide-ranging
pharmacological actions, especially in treating hypertension,
hyperlipemia, diabetes, obesity, sexual dysfunction, osteoporosis,
Alzheimer's disease, aging, lupus-like syndrome, and
Eucommia ulmoides has been used as a source of traditional medicine
and as a beneficial health food. Phytochemical and pharmacological
studies of Eucommia ulmoides have received much interest, and
extracts and active compounds continue to be isolated and proven to
exert various effects.
