  • Patent number: 10655061
    Abstract: The present invention relates to a process for the preparation of blue-fluorescence emitting carbon dots (CDTs) from sub-bituminous tertiary high sulfur Indian coals. More particularly, the present invention relates to the production of characteristics carbon dots from low-quality Indian coals by an ultrasonic-assisted wet-chemical method. Also, the present invention provides a simple and environmentally benign method for fabrication of characteristics and size-controlled carbon dots.

  • Patent number: 8912357
    Abstract: This invention is directed to the production of shikimic acid from Illicium griffithii fruits. The method according to the invention is particularly applicable to the isolation of shikimic acid from Illicium griffithii fruits (seeds and pericarps). Yield is 12-18% w/w. Shikimic acid is useful as raw material for the production of oseltavir (Tamiflu) used against Avian Flu. It is also reported that its triacyl derivatives can inhibit blood platelet assembling and Thrombosis by affecting the metabolism of Arachidonic acid. Hitherto known commercial methods of production of shikimic acid from the fruits of star anise (Illicium verum) and sweet gum (Liquidambar styraciflua) gives only 3-7% and 1.5% respectively. The price of shikimic acid in the international market varies from US$ 45.00 to 1000.00 per Kg depending on demand. Further as per report published at the website www.livemint.com, China Government has imposed restriction on export of shikimic acid.

  • Patent number: 5808117
    Abstract: The invention relates to a process for producing 16-Dehydropregnenolone acetate (16DPA) of the formula shown below ##STR1## which process comprises a) acetolysis of diosgenin of the formula shown below ##STR2## by heating in a pressure reactor in the presence of an acetylating agent and a non-polar solvent, maintaining the pressure in the reactor in the range of 4-6 kg/cm.sup.2 and at a temperature in the range of 200.degree.-250.degree. C. to produce pseudodiosgenine acetate of the formula shown below ##STR3## b) Oxidizing the so obtained pseudodiosgenin acetate to obtain diosone of the formula shown below ##STR4## and, c) Hydrolysis and degradation of the diosone so obtained to produce the said 16-Dehydropregnenolone acetate.
