| 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. |

| Shipping Condition | Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request. | ||
| Description | 1. Quercetin derivatives can be practically applied for the treatment and prevention of osteoporosis, since they effectively inhibit osteoclast proliferation and stimulate osteoblast proliferation more than conventional therapeutic agents for osteoporosis, and increase trabecular bone area highly without changing hormone level in body and untoward effects on hematopoietic function and immune system. |

A new flavonol glycoside and activity of compounds from the flower of Nymphaea candida.[Pubmed:17613618]
J Asian Nat Prod Res. 2007 Apr-Aug;9(3-5):333-8.
A new compound, kaempferol 3-O-(2''-O-galloylrutinoside) (1), was isolated from the white flower of Nymphaea candida, together with nine known flavonol glycosides, kaempferol (2), kaempferol 3-O-beta-D-glucopyranoside (3), kaempferol 3-O-alpha-l-rhamnopyranoside (4), kaempferol 3-O-alpha-l-rhamnopyranosylglucopyranoside (5), kaempferol 7-O-beta-D-glucopyranoside 3-(O-alpha-l-rhamnopyranosylglucopyranoside) (6), quercetin (7), Quercetin 3-O-beta-D-xylopyranoside (8), myricetin (9), myricetin 3'-O-beta-D-xylopyranoside (10). The structure of 1 was established on the basis of the analysis of its 1D and 2D NMR spectral data. Compounds 1-7 and 9 exhibited moderate to significant antioxidant activities, which were evaluated by measurement of low-density lipoprotein (LDL) and malondialdehyde (MDA) levels in vitro. Compounds 1, 3, 4, 6 and 9 exhibited promising neuroprotective effects on ischemic injury model of cultured rat cortical neurons treated with sodium dithionite in glucose-free medium. Furthermore, compounds 1, 5, and 9 had distinct cytotoxicity to adrenal gland pheochromocytoma, PC12 cells, being treated by the same way.
Bioactive phenolic compounds from the Egyptian Red Sea seagrass Thalassodendron ciliatum.[Pubmed:22888534]
Z Naturforsch C. 2012 May-Jun;67(5-6):291-6.
Five flavonoids (rutin, asebotin, 3-hydroxyasebotin, quercetin-3-O-beta-D-xylopyranoside, and a racemic mixture of catechin) and caffeic acid were isolated and identified for the first time from seagrass, Thalassodendron ciliatum, collected from the Hurghada region in Egypt. The crude extract and the isolated pure compounds were evaluated for their cytotoxic activities against HCT-116, HEPG, MCF-7, and HeLa human cancer cell lines, for their antiviral activity against Herpes Simplex and hepatitis A viruses, and for their antioxidant activity.
