| Description: |
Apterin has anti-inflammatory activity in vitro, it shows significantly inhibitory activity on nitric oxide production in RAW264.7 cells. |
| Targets: |
NO |
| In vitro: |
| J Agric Food Chem. 2003 Aug 27;51(18):5255-61. | | Antioxidant compounds from the leaves of Peucedanum japonicum thunb.[Pubmed: 12926867 ] | Seventeen compounds were isolated from the n-butanol soluble fraction of the leaves of Peucedanum japonicum Thunb.
METHODS AND RESULTS:
On the basis of MS and various NMR spectroscopic techniques, the structures of the isolated compounds were determined as isoquercitrin (1), rutin (2), 3-O-caffeoylquinic acid (3), 4-O-caffeoylquinic acid (4), 5-O-caffeoylquinic acid (5), cnidioside A (6), praeroside II (7), praeroside III (8), Apterin (9), esculin (10), (R)-peucedanol (11), (R)-peucedanol 7-O-beta-d-glucopyranoside (12), l-tryptophan (13), uracil (14), guanosine (15), uridine (16), and thymidine (17). All compounds except 11 and 12 were isolated for the first time from P. japonicum. Several isolated compounds were quantified by high-performance liquid chromatography analysis. In addition, all isolated compounds were examined for radical scavenging on 1,1-diphenyl-2-picrylhydrazyl radical and for inhibition of oxidation of liposome induced by 2,2'-azobis(2-amidinopropane)dihydrochloride.
CONCLUSIONS:
Compounds 2-5 were found to be the major potent constituents, which contribute to the antioxidant activity of P. japonicum leaves. |

| Chem Biodivers. 2017 Sep;14(9). | | A New Anti-Inflammatory Alkaloid from Roots of Heracleum dissectum.[Pubmed: 28556437 ] |
METHODS AND RESULTS:
Using various chromatographic methods, a new piperidinone alkaloid, (3S)-3-{4-[(1E)-3-hydroxyprop-1-en-1-yl]-2-methoxyphenoxy}piperidin-2-one (1), together with 10 known compounds, bergapten (2), xanthotoxol (3), isopimpinellin (4), isobergapten (5), heratomol-6-O-β-d-glucopyranoside (6), scopoletin (7), Apterin (8), 3-methoxy-4-β-d-glucopyranosyloxypropiophenone, (praeroside; 9), tachioside (10) and coniferin (11), were isolated from roots of Heracleum dissectum Ledeb. Their structures were elucidated on the basis of physicochemical properties and the detailed interpretation of various spectroscopic data.
CONCLUSIONS:
All the isolated compounds were screened for anti-inflammatory activity in vitro. As the results, compound 1 and 8 showed significantly inhibitory activity on nitric oxide production in RAW264.7 cells. |

Apterin Description
| Source: |
The herbs of Peucedanum decursivum Maxim. |
| Solvent: |
DMSO, Pyridine, Methanol, Ethanol, etc. |
| Storage: |
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.

| After receiving: |
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. |
