Description
Technical field
The present invention relates to field of pharmaceutical chemistry technology, particularly to a kind of compound, its extracting method, its
Prepare application and the antitumor drug of preparation thereof of antitumor drug.
Background technology
Oil tea (CameLLia oLeifera AbeL) belongs to Theaceae (Theaceae) Camellia (CameLLia
Linn), it is a kind of evergreen dungarunga.Because of its seed can extract oil (Oleum Camelliae) edible, therefore named oil tea.Oil
Tea is distributed mainly on the torrid zone and subtropical zone, originates in the west and south and the southeast of China, spreads all over 17 provinces
District.The unsaturated fatty acid content of Oleum Camelliae is up to 90%, significantly larger than vegetable oil, Oleum Arachidis hypogaeae semen and Oleum Glycines, with
Olive oil doubles than content of vitamin E, has high nutritive value, and therefore Oleum Camelliae receives much concern.
Additionally, oil tea also has the highest medical value, described in Compendium of Material Medica: " camellia oleosa seed, bitter cold is fragrant
Poison (Saponin), cures mainly dyspnea with rapid respiration cough, removes disease dirt ";" China book on Chinese herbal medicine " is the most on the books, the root of oil tea and
Root bark has effect of heat-clearing and toxic substances removing, regulating QI to relieve pain, promoting blood circulation and detumescence, cures mainly laryngopharynx swelling and pain, stomachache, tooth
Bitterly, traumatic pain, burn due to hot liquid or fire, its curative effect is considerably beyond Oleum Camelliae.But the medical value of oil tea is not affected by
Enough attention.
In recent years, chemical composition and the biological activity of oil tea are studied by people, at present, from
Isolated saponins, flavonoid, fatty acid in the Semen Camelliae of oil tea, Oleum Camelliae, Residuum Camelliae Semen preparatum, Camellia Leaves
Class, tannin, the fragrance compound such as glycoside, alkaloid.Research finds, part saponins compound has
The intestines and stomach protection, blood fat reducing, fat-reducing, antiallergic or antineoplastic effect.Ma Liyuan etc. find, oil tea tea
In sub-cake, the Total oil tea saponins of more than 95% has significant anti-tumor activity.Therefore, Sasanguasaponin has
The highest medical value.Sasanguasaponin mainly extracts from oil tea, but oil tea research is focused mostly on by people before
In Semen Camelliae, Residuum Camelliae Semen preparatum, Camellia Leaves, Oleum Camelliae, less to the research of oil tea root, oil tea root may be deposited
At undiscovered tool bioactive Sasanguasaponin compounds, therefore, to saponin constituent in oil tea root
Research have great importance.
