  • Preparation method of leaves extract and extract prepared by the method thereof
    Patent number: 10639343
    Abstract: A preparation method of Gynostemma Pentaphyllus leaves extracts with increased amount of small molecular effective saponin and decreased benzopyrene includes the steps of drying fresh Gynostemma Pentaphyllus leaves after heating, treating the dried Gynostemma Pentaphyllus leaves with steam, adding water of 1 to 100-fold volume to the above Gynostemma Pentaphyllus leaves and then preparing a hot water extract by carrying out a hot water extraction at 100-180 V, 0.5-10 atm for 1-120 hours, adding C1-C4 lower alcohol of 1 to 100-fold volume to the residual remained after the hot water extraction and then preparing an alcohol extract of the residual from the hot water extract by carrying out an alcohol extraction at 50-100° C. for 1-4 hours, and mixing the hot water extract and the alcohol extract, and then filtering and concentrating the mixture.

  • Process for preparing caspofungin and novel intermediates thereof
    Patent number: 9018349
    Abstract: The present invention relates to a novel process for preparing the aza cyclohexapeptide compound 1-[(4R,5S)-5-[(2-aminoethyl)amino]-N2-(10,12-dimethyl-1-oxotetradecyl)-4-hydroxy-L-ornithine]-5-[(3R)-3-hydroxy-L-ornithine]-pneumocandin B0 (caspofungin) represented by the following formula 1, which can improve the problem due to a pungent odor and toxicity during the process and can prepare caspofungin as a final product at high yield compared to conventional processes, and to novel intermediates which are used in the preparation process:
