Study On General Phenal Content Stability And Extraction Handicraft Of Lignum Sppan L

Lignum Sappan, the dried heartwood of Caesalpinia sappan L.,belongs to the family of Caesalpinaceae .It is also named for sappan, sappan wood, red wood, brown wood, red firewood and so on.It has been used in oriental medicine for a long time .Its pharmacology effect is broad, including immune inhibitory action , resisting the tumour effect , conquering the blood sugar effect , antibiosis the effect allaying inflammation , diuresis effect to the circulatory system effect , the calm analgesia effect, and so on.Pharmacology research discovers a logwood in recent years discriminating against a heart transplant reaction having stronger inhibitory action.Research indicates phenol , the general phenals is whose main pesticide effect material base.It includes brazilines,chalcones,dibezoxocin,derivatives,homoisoflavonoids and so on .To go with learning Lignum Sappan resist heart transplant rejective reaction,this text study and research the general phenol contents assay method,stabilitty,and handicraft of Lignum Sappan.In research, I first put the Heamatoxylin for standard thing, built Folin-law to determin the general phenals in Lignum Sappan , using this law admeasurement after study of method having the obvious stability.And process and result from the experiment are not bad reach,I optimize the extraction craft on the establishing the Folin-general law determin general phenal contents in lignum sappan ,by means of general phenol contents for consideration index.we have ascertained the best extractinghandicraft :A₂B₁C₂D₁,70% alcohol ,15 doubles , refluens extracting two times, every time 1 hour.In the end this text investigate the stability of the general phenol in lignum sppan.I study and research the illumination and temprature effect on stability.The result sign that the illuminition and temprature effect the stability significant.we must caution in the applying .The consequence guide the extraction and preparation of active part,active component and praeparatum of lignum sappan.In research, up to now,I first use Folin-phenol law to determin the general phenol contents,the extracting handicraft,and first research the stabiliyof genol phenol.The results establish rationale for immun-osuppressive action and active components researches.they had important significance for further making use of Caesalpinia Sappan L.
