[ character ]
Biological characteristics of hi temperature, afraid of the cold, the average monthly temperature at 25℃rapid growth. In deep soil, texture is loose and fecund arenaceous qualitative loam cultivation is appropriate.
Cultivation techniques of Cuttage Propagation for. In the spring of their not budding biennial Hale branch, cut grow20-25cm, according to the spacing30cm ×cm, obliquely inserted into the soil, cutting depth of 2/3, compaction after watering, cover film, long leaf and root, gradually remove the film bore. Breed1 years, transplanting, colonization, according to the spacing300cm ×300cm open pits, each pit planted1 strains. In addition, introduction and propagation by seeds in the spring, sowing seedling.
Field management after planting, weeding3-4 times a year, in spring1 applications of human excrement or urea, superphosphate fertilizer in summer1or compound fertilizer, winter1manure or fertilizer plant ash. Every time after fertilization to soil. Winter pruning.
[ ] leaf chemical composition containing Lagerstroemia acetal (lageracetal ) is two butoxy butane (1,1-dibutoxybutane ), amyl alcohol ( amyla1cohol ), and gallic acid ( el-lagic acid ). Also contains and gallic tannin components: Lagerstroemia tannins (lagerstannin ) A, B, C and pomegranate gluconic acid tannin ( punigluconin ); their structure were2,3:4,6- -O- ( S ) two - six hydroxy biphenyl acyl -D- glucose acid (2,3:4,6-bis-O- ( S ) -hexahydroxy diphenoyl-D-gluconicacig ),2,3,5-O- ( S, R ) - yellow gall three acyl -4,6-O- ( S ) two - six hydroxy biphenyl acyl -D- glucose acid (2,3,5-O- ( S, R ) -flavogalloyl-4,6-O- ( S ) -hexahydroxydiphenoyl-D-gluconic acid ),5-0- galloyl six hydroxyl radical -4,6-O- ( S ) - six hydroxy biphenyl acyl of two -D- glucose acid (5-O-galloyl-4,6-0- ( S ) -hexahydroxydiphenoyl-ngluconic acid ),2,5- two -O- galloyl4,6-O- ( S ) two - six hydroxy biphenyl acyl -D- glucose acid (2,5, di-O-galloya-4,6-O- ( S ) -hexahydroxy diphenoyl-D-gluconic acid ). It contains three terpene components: Maslinic Acid ( Maslinic Acid ) is 2α- hydroxy oleanolic acid (2 α -hydroxydeanolic acid ), coke threonic acid (colosolic acid ) is 2α- hydroxy ursolic acid (2 α -hydroxyursonic acid ). Also containing lipids ( Iipoid ) and 16 amino acids ( aminoacids ).
[ ] the pharmacological effects observed in a variety of plant extracts against Ehrlich ascites carcinoma cell uptake of export glucose role after the discovery of Lagerstroemia specious, to promote the uptake of plants. From separation to cola Su acid and Maslinic Acid two three terpenoids, former for glucose transport facilitating compounds, therefore with hypoglycemic activity.
