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.

[Homoisoflavanones and stilbenes from fresh bulb of Scilla scilloides].[Pubmed:25612441]

Zhongguo Zhong Yao Za Zhi. 2014 Oct;39(19):3788-93.

Mian-Zao-Er was collected from the bulbs of Scilla scilloides (Lindl. ) Druce, belonging to the Hyacinthaceae family. 17 compounds were obtained using various column chromatographies on macroporus resin (HPD100), silica gel, Sephadex LH-20 and ODS, as well as semi-preparative HPLC. Their structures were elucidated on the basis of physicochemical properties and spectral data as 2-hydroxy-7-methoxyscillascillin (1), scillascillin (2), 5,7-dihydroxy-3',4'-dimethoxyspiro 2H-1-benzopyran-7'-bicyclo[4.2.0 ] octa [1,3,5 ] -trien -4-one (3), socialinone (4), 4-methylresveratrol (5), (E)-resveratrol (6), scillavoneA (7), 3,9-di- hydroeucomnalin (8), 3-(3-hydroxy-4-methoxybenzyl) -5,7-Dihydroxychroman-4-one (9), (3R)-5,7,3'-trihydroxy-4'-methoxyspiro (2H-1-benzopyran-7'-bicyclo[4, 2, 0] octa [1, 3, 5]-trien -4-one (10), scillabene A (11), 2-hydroxyscillascillin (12), 3-(4-hydroxybenzyl) -5,7-Dihydroxychroman-4-one (13), 3-( 4-hydroxybenzylidene) -5, 7-dihydroxychroman-4-one (14), 3-( 4-hydroxybenzyl) -5-hydroxy-7,8-dimethoxychroman-4-one (15), 3-(4-hydroxybenzyl) -5-hydroxy-6, 7-dimethoxychroman-4-one (16), and 3-(4-hydroxybenzyl)-5,8-hydroxy-7-methoxychroman-4-one (17). Among them, compounds 3, 4, 6, 9, 13 and 15-17 were isolated from this plant for the first time.

COX-2 inhibitory activity of homoisoflavanones and xanthones from the bulbs of the Southern African Ledebouria socialis and Ledebouria ovatifolia (Hyacinthaceae: Hyacinthoideae).[Pubmed:23859260]

Phytochemistry. 2013 Nov;95:284-90.

The bulbs of Ledebouria socialis (Hyacinthaceae) yielded the benzocyclobutene homoisoflavonoid, (R)-2',5-dihydroxy-3',4',7-trimethoxyspiro2H-1-benzopyran-3-(4H)-9-bicyclo[4.2.0]octa[1,3,5]triene-4-one, socialinone (1). Ledebouria ovatifolia yielded (2epsilon,3R)-2,5-dihydroxy-7-methoxyspiro[2H-1-benzopyran-3(4H), 5'(6'H)-cyclobuta[f][1,3]benzodioxol]-4-one (2) and the homoisoflavanone, (E)-3-(3',4'-dihydroxybenzylidene)-5,7-Dihydroxychroman-4-one, ovatifolionone (5), the dihydrochalcone, 4,4'-dihydroxy-2',6'-dimethoxydihydrochalcone (3), and xanthone, 1,6-dihydroxy-2,3,5-trimethoxy-8-methyl-9H-xanthen-9-one (4) along with 21 known compounds. Structures were determined using spectroscopic techniques. The anti-inflammatory activities of the homoisoflavonoids and xanthones isolated were evaluated against cyclooxygenase-1 and -2 isoenzymes. (R)-3-(3',4'-Dihydroxybenzyl)-7-hydroxy-5-methoxychroman-4-one (7), (E)-3-(3',4'-dihydroxybenzylidene)-7-hydroxy-5-methoxychroman-4-one (10), 1,3,6-trihydroxy-2-methoxy-8-methylxanthen-9-one (6) and ovatifolionone acetate (5Ac) exhibited significant activity against cyclooxygenase-2 at <10muM.
