Abstract
The invention discloses sansevieria trifasciata saponin, a preparation method and application thereof. The method comprises the following steps of: making the sansevieria trifasciata into dry powder, extracting by using water, alcohol or methanol, extracting by using petroleum ether or ether, and extracting by using butyl alcohol or pentanol to obtain the sansevieria trifasciata total saponin extract. The method for preparing the sansevieria trifasciata saponi optimizes the process conditions, has simple operation and low cost, has low requirement on process equipment, can reduce the consumption of solvents and enhance the leaching rate. The sterilized sansevieria trifasciata has obvious inhibition function on the growth of JurKet, has no activity killing effect on human cervical carcinoma cells (HeLa) and human gastric carcinoma cells (BGC823), and has no injury to normal Chinese Hamster Ovary (CHO), and the cell grows normally without any obvious change.
Description
Technical field
The present invention relates to a kind of extraction of vegetable active composition, specifically Sansevieria trifasciata saponin and its production and application
Background technology
Budgerigar orchid (Sansevieria trifasciata) has another name called Folium Sansevieriae Trifasclatae, Your Highness orchid, is the perennial meat herbaceous plant of Agavaceae, Folium Sansevieriae Trifasclatae genus.Originate in Africa, India, belong to desert plant, can restrain oneself harsh environmental conditions, strong to the adaptability of environment, easily breeding, growth are liked temperature climate soon, and be cold-resistant, the preference temperature of growth is 20-30 ℃, can stop growing when temperature is lower than 13 ℃, and the temperature of surviving the winter can not be lower than 8 ℃.The Budgerigar orchid has the root stock of crawling to grow, and blade directly grows from rhizome, and blade is strong upright.
At present, point out that the Budgerigar orchid has the effect that purifies the air of a room in a lot of reports.It can discharge oxygen in absorbing carbon dioxide, the negative ion concentration in the room air is increased.It is reported that 2-3 basin Budgerigar orchid is put in indoor at 15 square metres, just can absorption chamber in harmful gas more than 80%.It also has the ability of very strong absorption formaldehyde, therefore is called by people " natural street cleaner ".
The Budgerigar orchid also has effects such as heat-clearing and toxic substances removing, promoting flow of QI and blood, relaxing muscles and tendons and activating QI and blood in the collateral, and diseases such as cardiovascular, gastric ulcer, arteriosclerosis are had therapeutic efficiency.The Budgerigar orchid also has the effect of antiinflammatory, heat-clearing and toxic substances removing, in addition, and can also the lowering blood-fat and reducing weight blood pressure lowering.Not only do not suffer tremendous loss in strength or resources, can supplement the nutrients on the contrary, increase effects such as human body energy.
Saponin (Saponins) is the glycosides compound that is present in a botanic class formation more complicated, and its aglycon belongs to mostly and has spirostane and similar steroid or the triterpenoid compound of source of students thereof.Can produce persistent foam after the jolting of most of saponin aqueous solution, so claim saponin.Up to the present, the saponins compound of Fa Xianing mainly is distributed in the plant of 15 sections in the world, and wherein the shared quantity of monocotyledon is more, and 41 genus of 9 sections are arranged, and mainly concentrates in the subjects such as Dioscoreaceae, Agavaceae, Liliaceae.Chinese medicine that some are commonly used such as Radix Ginseng, Radix Bupleuri, Radix Notoginseng, Semen Ziziphi Spinosae, Herb Gynostemmae Pentaphylli etc. all contain a large amount of steroidal saponins.The saponin aboundresources of China, wherein more, than system with the report of saponin in the Araliaceae, use also relatively extensively, as Radix Ginseng, Radix Panacis Quinquefolii etc.In addition, in recent years the research report of saponin in Dioscoreaceae, strand Landtek, the Liliaceae is also day by day increased.
Saponin by sapogenin (Sapogenins) and sugar, alduronic acid, also might be to form with other organic acid.The common sugar of forming saponin has glucose, galactose, rhamnose, arabinose, wooden sugar and other pentose class.Common alduronic acid has galacturonic acid, glucuronic acid etc.These glucosides alduronic acid are the forms that are combined into sugar chain (oligosaccharide) earlier, link to each other with sapogenin again, and a few cases is that the form with monosaccharide links to each other with sapogenin.
The saponin kind is numerous and diverse, according to the chemical constitution difference of sapogenin, saponin can be divided into triterpene saponin (TriterpenoidSaponins) and steroidal saponin (Steroid Saponins).Up to now, from plant, just isolated more than 400 kind of steroidal saponin.Also do not have but the single component saponin directly applies to clinical medicine, and with the plant variety difference, effect also is not quite similar.
The spiral sterin alkane saponin of taking from Folium Dracaenae cambodianae has anti-gram positive bacteria effect with the astersaponin of taking from Asterias amurensis Lutken.
Take from Radix Glycyrrhizae monopotassium glycyrrhizunate (a kind of amyrin saponin) but external concentration deactivation Measles virus and herpesvirus when 5 μ mol/L.Saikoside (a kind of β balsam saponin) can suppress multiple DNA and RNA viruses, irreversibly deactivation herpes simplex virus, and (human immunodeficiency virus HIV) also has inhibitory action to HIV (human immunodeficiency virus).
The Dodonoside A that obtains from aalii (Sapindaceae) can reduce mice pawl angle dish glue and cause edema 33%, and the Crossop tine B that obtains from Rubiaceae is better than aspirin and aescine reducing the effect that mice pawl angle dish glue causes aspect the edema.The saponin that obtains from Quillaia saponaria (Rosaceae) is studied for many years at world wide, and it is gone on the market as immune adjuvant.
Cardiac glycoside (lanatoside) is a class has the important compound of unique effect to heart, and they are all on the books in many medical books.At present, the steroidal saponin of single component directly applies to clinical medicine also not to be had, but total steroidal saponin is more in clinical practice as the medicine of treatment diseases of cardiovascular and cerebrovascular systems, and evident in efficacy.Such as: by the pure Chinese medicinal preparation that contains 8 kinds of steroidal saponins---the DIAOXINXUE KANG JIAONANG that extracts in the Dioscorea panthaica Prain et Burkill (Dioscoreapanthaica), preparation---the Xinnao Shutong of being developed by Fructus Tribuli (Tribulusterrestris) fruit total steroid saponin.Preparation by Rhizoma Dioscoreae Zingiberensis (Dioscoreazingiberensis) rhizome water-solubility saponin development---peltate leaf perhexiline and the main component of using clinically are the decoction etc. Radix Ophiopogonis of steroidal saponin.These medicines are at aspects such as the sequela for the treatment of coronary heart disease, angina pectoris, myocardial ischemia, cerebral arteriosclerosis and cerebral thrombosis, chronic pulmonary heart diseases, and clinical effectiveness is very remarkable.
Chlorophytum malayense has potential cytotoxicity to tumor; Solanum nigrum is used for various treatment for cancer in China and Japan; The Herba Phyllanthi Urinariae also treats at the antineoplastic that is used among the people.
