| 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. |

Procyanidins from the stem wood of Machilus japonica and their inhibitory effect on LDL oxidation.[Pubmed:24297667]
Arch Pharm Res. 2014 Nov;37(11):1403-10.
The stem wood of Machilus japonica Siebold & Zucc were extracted with 80 % aqueous MeOH, and the concentrated extract was successively partitioned with ethyl acetate (EtOAc), normal butanol, and water. From the EtOAc fraction, five procyanidins, procyanidin A1 (1), procyanidin A2 (2), Procyanidin B7 (3), cinnamtannin B1 (4), and aesculitannin B (5), were isolated. Their chemical structures were identified through spectroscopic data analyses including NMR, MS, and IR. This is the first time any of these compounds have been isolated from this plant. The compounds were evaluated for inhibition activity on LDL oxidation. All of these compounds and the positive control, BHT, showed a very high inhibition effect with IC50 values of 0.94, 2.1, 1.8, 1.1, 1.0, and 1.9 muM, respectively.
Characterization of plum procyanidins by thiolytic depolymerization.[Pubmed:18540618]
J Agric Food Chem. 2008 Jul 9;56(13):5188-96.
The phenolic compounds of 'Green Gage' (GG) plums ( Prunus domestica L.), "Rainha Claudia Verde", from a 'protected designation of origin' (PDO), in Portugal, were quantified in both flesh and skin tissues of plums collected in two different orchards (GG-V and GG-C). Analyzes of phenolic compounds were also performed on another GG European plum obtained in France (GG-F) and two other French plums, 'Mirabelle' (M) and 'Golden Japan' (GJ). Thiolysis was used for the first time in the analysis of plum phenolic compounds. This methodology showed that the flesh and skin contain a large proportion of flavan-3-ols, which account, respectively, for 92 and 85% in GJ, 61 and 44% in GG-V, 62 and 48% in GG-C, 54 and 27% in M, and 45 and 37% in GG-F. Terminal units of procyanidins observed in plums are mainly (+)-catechin (54-77% of all terminal units in flesh and 57-81% in skin). The GJ plums showed a phenolic composition different from all of the others, with a lower content of chlorogenic acid isomers and the presence of A-type procyanidins as dimers and terminal residues of polymerized forms. The average degree of polymerization (DPn) of plum procyanidins was higher in the flesh (5-9 units) than in the skin (4-6 units). Procyanidin B7 was observed in the flesh of all GG plums and in the skin of the Portuguese ones. Principal component analysis of the phenolic composition of the flesh and skin of these plums obtained after thiolysis allowed their distinction according to the variety and origin, opening the possibility of the use of phenolic composition for variety/origin identification.
