Biological Activity
Description: Barbinervic acid shows anti-bacteria activity (IC50 = 0.098 g x LU(-1), IC50 = 0.27 g x L(-1)) against SA and ESBLs-SA respectively.
Targets: Antifection
In vitro:

Anti-bacteria activity of Puraboeo rutescens and Lysionotus pauciflorus.[Pubmed: 22016971]
Antibacteria activity of compounds from Puraboeo ruescens and Lysionotus pauciflorus was assayed.
METHODS AND RESULTS:
Disc diffusion was used to isolate compounds in vitro and berberine was positive control. The value of IC50 was assayed by the method of liquid culture. All kinds of chromatography were used to isolate the chemical constituent and structure was identified by MS and NMR spectroscopy. Eight compounds were isolated and identified as beta-sitosterol (1), E-3,4-dihydroxy cinnamic acid (2), Barbinervic acid (3), 3beta,19alpha-dihydroxy12-en-28-ursolic acid (4), 28-O-beta-D-glucopyranosyl pomolic acid (5), 5,7-dihydroxy-6,8,4'-trimethoxy flavone (6), 5, 6, 4'-trihydroxy-7,8-dihydroxy flavone (7), 5-hydroxy-6,8,4'-trimethoxy flavone-7-O-beta-D-glucopyranosyl (8). Compound 3, 4 and 6 had activity against SA, MRSA and ESBLs respectively. Compound 3 showed (IC50 = 0.098 g x LU(-1), IC50 = 0.27 g x L(-1)) against SA and ESBLs-SA respectively. Compound 4 (IC50 = 0.130 g x L(-1)) was best to against MR SA.
CONCLUSIONS:
Compound 1 - 5 were isolated from this plant for the first time. Compound 7 and 8 was isolated from Gesneriaceae for the first time.
Barbinervic acid Description
Source: The leaves of Diospyros kak.
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. 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.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

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.

Isolation and absolute stereochemistry of coussaric acid, a new bioactive triterpenoid from the stems of Coussarea brevicaulis.[Pubmed: 12946428]

METHODS AND RESULTS:
Coussaric acid (1), a triterpenoid based on an ursane skeleton, and an oleanane-type triterpene acid, 3-epi-spathodic acid (2), as well as four known compounds, Barbinervic acid, scutellaric acid, stigmasterol and stigmasterol glucoside, have been isolated from an EtOAc-soluble extract of the stems of Coussarea brevicaulis. The structures of compounds 1 and 2 were elucidated on the basis of spectroscopic investigation, and single-crystal X-ray crystallography was used to confirm the structure of 1. The absolute stereochemistry of 1 was established by chemical transformations and by the Mosher ester procedure.
CONCLUSIONS:
The potential of the isolates and chemical transformation products to induce quinone reductase was evaluated in mouse Hepa lclc7 hepatoma cells.
