| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

| About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

Homoisoflavonoids and Related Compounds. V.1) A Novel Dibenzoxocin Derivative from Caesalpinia sappan L
Chem. Pharm. Bull.,1987,35(9):3615-9.
We have been further studying the isolation, absolute stereochemistries and biosyntheses of the phenolic constituents of C. sappan and C. japonica. In the present paper,we report the isolation and structural elucidation of a novel dibenzoxocin derivative,10-O-Methylprotosappanin B(1), from Sappan Lignum.10-O-Methylprotosappanin B (1) was obtained by repeated silica gel and Sephadex LH-20 column chromatography, and preparative thin-layer chromatography (PTLC) of the remaining fractions after separation of the previously reported compounds.4) The isolation of the intact compound was so difficult that only a limited amount could be obtained. However, a satisfactory amount was obtained in the form of an isopropylidene derivative (6) from the methanolic extract separated after treatment with acetone in the presence of an acid catalyst, as described in the previous paper.4c) The remaining fractions after isolation of the isopropylidene derivatives of 3,4-dihydroxy homoisoflavans4c) were subjected to column chromatography on silica gel and Sephadex LH-20 to yield 6, together with the isopropylidene derivative of protosappanin B (7). On acid hydrolysis with 60% AcOH, compound 6 was readily transformed into 1
