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
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.

Meroterpenoid pigments from the basidiomycete Albatrellus ovinus.[Pubmed:
23305465]
METHODS AND RESULTS:
Eight grifolin derivatives, involving three new monomers, albatrelins A-C (1-3), three novel dimers (meroterpenoid pigments), albatrelins D-F (4-6), and two known ones, 6a,7,8,9,10,10a-hexahydro-3,6,9-trimethyl-6-(4-methyl-3-penten-1-yl)-1,9-epoxy-6H-dibenzo[b,d]pyran (7) and Confluentin (8), were isolated from Albatrellus ovinus. Their structures were established by extensive spectroscopic analysis. The absolute configurations of compounds 2-4 were determined as 9R by comparing their optical rotations with data reported in the literature.
CONCLUSIONS:
Albatrelin F (6) was isolated as a pair of C-2' tautomers with a ratio of 1.3:1. Confluentin (8) showed weak cytotoxicity against four human tumor cell lines, HL-60, SMMC-7712, A-549, and MCF-7, in vitro.

Activities of prenylphenol derivatives from fruitbodies of Albatrellus spp. on the human and rat vanilloid receptor 1 (VR1) and characterisation of the novel natural product, confluentin.[Pubmed:
12761765]
Several prenylphenols from basidiocarps of European and Chinese Albatrellus spp., namely grifolin (1), neogrifolin (2), Confluentin (3), scutigeral (4), and albaconol (5) were investigated concerning their activities in test models for vanilloid receptor modulation.
METHODS AND RESULTS:
The isolation of these compounds from A. confluens and structure elucidation of the novel natural product Confluentin (3) are described. The effects of scutigeral and neogrifolin on vanilloid receptors were studied by means of electrophysiological methodology on rat dorsal root ganglion neurons as well as on recombinant cell lines expressing the rat VR1 receptor. Concurrently, the effects of compounds 1-5 on a reporter cell line expressing the human vanilloid receptor VR1 were measured.
CONCLUSIONS:
In contrast to previous studies reported in the literature, the results of these investigations suggest that fungal prenylphenols act as weak antagonists (activity in the microM range), rather than exhibiting agonistic activities.

Antibacterial compounds from mushrooms I: a lanostane-type triterpene and prenylphenol derivatives from Jahnoporus hirtus and Albatrellus flettii and their activities against Bacillus cereus and Enterococcus faecalis.[Pubmed:
19644795]
METHODS AND RESULTS:
Antibacterial bioassay-guided fractionation of two American mushroom species, Jahnoporus hirtus and Albatrellus flettii, led to the isolation and identification of their major antibacterial constituents: 3,11-dioxolanosta-8,24( Z)-diene-26-oic acid (1) from J. hirtus and Confluentin (2), grifolin (3), and neogrifolin (4) from A. flettii. Compound 1 is a new lanostane-type triterpene. All purified compounds were evaluated for their ability to inhibit the growth of Bacillus cereus and Enterococcus faecalis using standard MIC assays. Compounds 1- 4 demonstrated MIC values of 40, 20, 10, and 20 microg/mL, respectively, against B. cereus and MIC values of 32, 1.0, 0.5, and 0.5 microg/mL, respectively, against E. faecalis.
CONCLUSIONS:
Thus, one novel compound and three others were shown to possess antimicrobial activities against these gram-positive bacteria employed as surrogates for more virulent and dangerous pathogens.

Structures and histamine release inhibitory effects of prenylated orcinol derivatives from Rhododendron dauricum.[Pubmed:
15270561]
METHODS AND RESULTS:
Four new prenylated orcinol derivatives, daurichromenes A-D (1-4), along with three known compounds, Confluentin (5), grifolin (6), and orcinol (7), have been isolated from the Chinese medicinal plant Rhododendron dauricum. Their structures were established as 2R-(7'-hydroxy-4',8'-dimethyl-3'E,8'-nonadienyl)-5-hydroxy-2,7-dimethyl-2H-chromene (1), 2R-(3'-hydroxy-8'-methyl-4'-methyliden-7'-nonaenyl)-5-hydroxy-2,7-dimethyl-2H-chromene (2), 2R-(8'-hydroxy-4',8'-dimethyl-3'E,6'Z-nonadienyl)-5-hydroxy-2,7-dimethyl-2H-chromene (3), and 2R-(9'-hydroxy-4',8'-dimethyl-3'E,7'E-nonadienyl)-5-hydroxy-2,7-dimethyl-2H-chromene (4) by analysis of spectral data.
CONCLUSIONS:
The absolute configuration of the asymmetric carbons at the chromene ring in 1-5 was determined as R from their circular dichroism spectra. Compounds 1-6 significantly inhibited compound 48/80-induced histamine release from rat peritoneal mast cells.
