| 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. |

Inhibitory Effect on beta -Hexosaminidase Release from RBL-2H3 Cells of Extracts and Some Pure Constituents of Benchalokawichian, a Thai Herbal Remedy, Used for Allergic Disorders.[Pubmed:25580152]
Evid Based Complement Alternat Med. 2014;2014:828760.
Introduction. Benchalokawichian (BCW), a Thai traditional herbal formulation, has long been used as antipyretic and to treat skin disorders. It comprises roots from five herbs: Ficus racemosa, Capparis micracantha, Clerodendrum petasites, Harrisonia perforata, and Tiliacora triandra. This polyherbal remedy has recently been included in the Thailand National List of Essential Medicines (Herbal Products list). Methodology. A Bioassay-guided fractionation technique was used to evaluate antiallergy activities of crude extracts, and those obtained by the multistep column chromatography isolation of pure compounds. Inhibitory effect on the release of beta-hexosaminidase from RBL-2H3 cells was used to determine antiallergic activity. Results. Two pure compounds from BCW formulation showed higher antiallergic activity than crude or semipure extracts. Pectolinarigenin showed the highest antiallergic activity, followed by O-Methylalloptaeroxylin, with IC50 values of 6.3 mug/mL and 14.16 mug/mL, respectively. Moreover, the highest activities of pure compounds were significantly higher than chlorpheniramine (16.2 mug/mL). Conclusions. This study provides some support for the use of BCW in reducing itching and treatment of other skin allergic disorders. The two isolated constituents exhibited high antiallergic activity and it is necessary to determine their mechanism of action. Further phytochemical and safety studies of pure compounds are required before development of these as antiallergy commercial remedies.
Chromones from the branches of Harrisonia perforata.[Pubmed:16394547]
Chem Pharm Bull (Tokyo). 2006 Jan;54(1):44-7.
Four new chromones, perforamone A, B, C, and D have been isolated together with six known compounds, peucenin-7-methyl ether, O-Methylalloptaeroxylin, perforatic acid, eugenin, saikochromone A and greveichromenol, from the branches of Harrisonia perforata (Simaroubaceae). The structures were identified by spectroscopic data. The compounds were tested for antimycobacterial and antiplasmodial activities.
Cedkathryns A and B, pentanortriterpenoids from Cedrelopsis gracilis (Ptaeroxylaceae).[Pubmed:15501263]
Phytochemistry. 2004 Nov;65(21):2929-34.
The stem bark of Cedrelopsis gracilis (Ptaeroxylaceae) has yielded three known prenylated coumarins, O-Methylalloptaeroxylin, ptaerochromenol and umtatin and the novel pentanortriterpenoids, cedkathryn A and cedkathryn B.
