 OUR COLLECTIONS OF PURIFIED NATURAL PRODUCTS & THEIR SYNTHETIC DERIVATIVES/MIMICS


Please note that we are not a commercial supplier of natural products - We do not own  products designed for making profits!

We routinely isolate a range of small molecular weight compounds from medicinal plants while our semi-synthesis work on the isolated compounds yields various natural product derivatives. We also routinely synthesise a range of natural product mimics. These products which are excess to our requirement are available for research uses.  All of our products are certified with the highest degree of analytical standard.

Example 1: Purified natural products

Bergenin is our classic example

Bergenin - (2R,3S,4S,4aR,10bS)-3,4,8,10-Tetrahydroxy-2-(hydroxymethyl)-9-methoxy-3,4,4a,10b-tetrahydropyrano[3,2-c]isochromen-6(2H)-one

The various purity ranges of bergenin that we worked are between 95% to ultra-pure crystalline grades.

 

Bergenin

HAS-BERG-95

HAS-BERG-99

HAS-BERG-ULTRA

 

Molecular Formula: C14H16O9

Average mass: 328.271393 Da

 

We grow Bergenia species in our own medicinal garden  from which bergenin is isolated.


Example 2: Semi-synthetic natural products

Gallic acid derivatives are our classic examples

We have a range of structurally uncommon gallic acid derivatives with unique methylation and acetylation pattern. Two examples are shown below.
