Sanggenon N shows protective effects on t-BHP-induced oxidative stress with the EC50 value of 23.45 ± 4.72 uM. It inhibits lipopolysaccharide-induced nitric oxide production in RAW 264.7 macrophages.
Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to
24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Isoprenylated flavonoids from the root bark of Morus alba and their hepatoprotective and neuroprotective activities.[Pubmed:
25981820]
METHODS AND RESULTS:
A new isoprenylated flavonoid, 2S-5,7,2',4'-tetrahydroxy-3',5'-di-(γ,γ-dimethylallyl)flavanone, sanggenol Q (1), along with seven known isoprenylated flavonoids, sanggenol A (2), sanggenol L (3), kuwanon T (4), cyclomorusin (5), sanggenon F (6), sanggenol O (7), and Sanggenon N (8), three known Diels-Alder type adducts, sanggenon G (9), mulberrofuran G (10), and mulberrofuran C (11), and a known benzofuran, moracin E (12), were isolated from the root bark of Morus alba using silica gel, ODS, and Sephadex LH-20 column chromatography. Chemical structures were determined based on spectroscopic data analyses including NMR, MS, CD, and IR. For the first time, compounds 1 and 7 were isolated from the root bark of M. alba. All compounds were evaluated for hepatoprotective activity on t-BHP-induced oxidative stress in HepG2 cells and neuroprotective activity on glutamate-induced cell death in HT22 cells.
CONCLUSIONS:
Compounds 1, 4, 8, 10, and 11 showed protective effects on t-BHP-induced oxidative stress with EC50 values of 6.94 ± 0.38, 30.32 ± 6.82, 23.45 ± 4.72, 15.31 ± 2.21, and 0.41 ± 0.48 μM, respectively, and compounds 1, 2, 10, 11, and 12 showed protective effects on glutamate-induced cell death with EC50 values of 5.54 ± 0.86, 34.03 ± 7.71, 19.71 ± 0.71, 16.50 ± 7.82, and 1.02 ± 0.13 μM, respectively.

Isoprenylated flavonoids from the root bark of Morus alba L. and their inhibition effect on NO production in LPS-induced RAW 264.7 cells[Reference:
WebLink]
METHODS AND RESULTS:
The root bark of Morus alba L. were extracted with 80% aqueous MeOH, and the concentrated extract was partitioned with EtOAc, n-BuOH, and H2O fractions. The repeated silica gel (SiO2), octadecyl SiO2 (ODS), and Sephadex LH-20 column chromatographies of the EtOAc fraction led to isolation of 12 phenolic compounds.
CONCLUSIONS:
The chemical structures of the compounds were determined as sanggenol Q (1), sanggenol A (2), sanggenol L (3), kuwanon T (4), cyclomorusin (5), sanggenon F (6), sanggenol O (7), Sanggenon N (8), sanggenon G (9), mulberrofuran G (10), mulberrofuran C (11), and moracin E (12). All isolated compounds were evaluated for inhibit lipopolysaccharide-induced nitric oxide production in RAW 264.7 macrophages.
