| 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. |

Efficient synthesis of cis- and trans-3,4-dihydroxy-3,4-dihydromollugin.[Pubmed:18412388]
J Org Chem. 2008 May 16;73(10):3867-74.
An efficient synthesis of naturally occurring compounds isolated from Pentas longiflora, cis-3,4-dihydroxy-3,4-Dihydromollugin 2, and trans-3,4-dihydroxy-3,4-Dihydromollugin 3 is described. The O-protected mollugins were dihydroxylated using OsO4 to achieve the corresponding cis-dihydroxy derivatives in excellent yield. The synthesis of trans-3,4-dihydroxy-3,4-Dihydromollugin was achieved using Oxone in good yield. A mechanism for the formation of cis-3,4-dihydroxymollugin acetonide from the reaction of mollugin with Oxone is proposed.
New pyranonaphthoquinone and pyranonaphthohydroquinone from the roots of Pentas longiflora.[Pubmed:12350172]
J Nat Prod. 2002 Sep;65(9):1377-9.
Several quinone type compounds were isolated from the hexane, dichloromethane, and ethyl acetate extracts of the roots of Pentas longiflora. The hexane extract afforded two new compounds, [(3alpha,3'alpha,4beta,4'beta)-3,3']-dimethoxy-cis-[4,4'-bis(3,4,5,10-tetrahydro- 1H-naphtho[2,3-c]pyran)]-5,5',10,10'-tetraone (1) and cis-3,4-dihydroxy-3,4-Dihydromollugin (2), together with six known compounds, namely, pentalongin, mollugin, trans-3,4-dihydroxy-3,4-Dihydromollugin, methyl-2,3-epoxy-3-prenyl-1,4-naphthoquinone-2-carboxylate, tectoquinone, and 3-hydroxymollugin. From the dichloromethane extract were isolated the three known compounds 3-methoxymollugin, methyl-3-prenyl-1,4-naphthoquinone-2-carboxylate, and scopoletin, while the ethyl acetate extract afforded the known 2-methoxy-3-methylanthraquinone.
[Studies on naphthoic acid esters from the roots of Rubia cordifolia L].[Pubmed:1442042]
Yao Xue Xue Bao. 1992;27(4):279-82.
Four naphthoic acid esters including a new compound were isolated from the roots of Rubia cordifolia L. The new one was named as rubilactone and its structure was elucidated as 3'-carbomethoxy-4'-hydroxy-naphtho[1',2'-2,3] pyran-6-one (I) based on the physicochemical properties and spectrometric analyses (UV, IR, MS, 1HNMR and 13CNMR). The other three were 3'-carbomethoxy-4'-hydroxy-naphtho [1',2'-2,3] furan (II), Dihydromollugin (III) and 3-carbomethoxy-2-(3'-hydroxy)isopentyl-1,4-naphthohydroquinone-1-O -beta-D-glucoside (IV).
