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.
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.

Chemical constituents of stems and branches of Adina polycephala.[Pubmed: 20707194]

Zhongguo Zhong Yao Za Zhi. 2010 May;35(10):1261-71.

To investigate chemical constituents of the stems and branches of Adina polycephala and their pharmacological activities.
METHODS AND RESULTS:
The constituents were isolated by a combination of various chromatographic techniques including column chromatography on silica gel, Sephadex LH-20, and C-18, as well as reversed-phase HPLC. Structures of the isolates were identified by spectroscopic data analysis. In vitro cytotoxic, anti-inflammatory, anti-oxidant, anti-HIV, neuroprotective and anti-diabetic activities were screened by using cell-based models. Twenty-eight constituents were isolated. Their structures were identified as clemochinenoside B (1), Kelampayoside A (2), osmanthuside H (3), 4-hydroxy-3-methoxyphenol-beta-D-[6-O-(4-hydroxy-3,5-dimethoxylbenzoate)]-glucopyranoside (4), and syringic acid beta-D-glucopyranosyl ester (5). Ten iridoidal glycosides: geniposidic acid (6), geniposide (7), 6beta-hydroxygeniposide (8), 6beta-hydroxygeniposide (9), ixoside (10), ixoside 11-methyl ester (11), 11-methyl forsythide (12), 7beta-hydroxysplendoside (13), gardoside (14) and mussaenosidic acid (15), (+) -pinoresinol (16), (+) -medioresinol (17), (+) -syringaresinol (18), (-)-lariciresinol (19), evofolin-B (20), alpha-hydroxyacetovaillone (21), syringic acid (22), vanillin (23), 3, 4, 5-trimethoxyphenol (24), and 2,6-dimethoxy-1, 4-benzoquinone (25), beta-sitosterol (26), mannitol (27), and daucosterol (28). At a concentration of 1.0 x 10(-5) mol x L(-1), these compounds were inactive in the assays, including cytotoxicity against human tumor cell lines (HCT-8, Bel-7402, BGC-823, A549 and A2780), anti-inflammatory activity against the release of beta-glucuronidase in rat polymorphonuclear leukocytes (PMNs) induced by platelet-activating factor (PAF), antioxidant activity in Fe(2+)-cystine-induced rat liver microsomal lipid peroxidation, anti-HIV activity against HIV-1 replication, neuroprotective activity against serum deprivation or glutamate induced neurotoxicity in cultures of PC12 cells, and the inhibitory activity against protein tyrosine phosphatase 1B (PTP1B).
CONCLUSIONS:
Compounds 1-20 were obtained from the genus Adina for the first time. The 13C-NMR data of compounds 10 and 11 were reassigned. A further evaluation of pharmacological activity of these compounds is expected.

Study on chemical constituents of Callicarpa peii.[Pubmed: 24134001]

To study the chemical constituents of Callicarpa peii.
METHODS AND RESULTS:
The chemical constituents were isolated and purified by chromatographic methods and elucidated by spectral analysis, including UV, IR, MS, 1H-NMR and 13C-NMR. Ten compounds were obtained and identified as oleanolic acid (1), 2beta, 3beta,19alpha-trihydroxy-12-en-28-ursolic acid (2), luteolin -7,4'-dimethylether (3), luteolin -3', 4', 7, -trimethylether (4), luteolin -4'-methylether (5), hydnocarpin (6), luteolin (7), lyoniresinol 3alpha-O-beta-D-glucopyranoside (8), Kelampayoside A (9), kaempferol -3-O-glucuronide (10).
CONCLUSIONS:
All these compounds are isolated from Callicarpa peii for the first time and compounds 3, 4, 6, 8 and 10 are isolated from this genus for the first time.
