MUMBAI, India, Oct. 24 -- Intellectual Property India has published a patent application (202441031772 A) filed by Dr. Sabincar Uvaraj Sreerama Chandar, Vijayawada, Andhra Pradesh, on April 22, 2024, for 'simple, easy, fast and cheap single step unconventional methods for preparation of aqueous extracts of various parts of neem.'
Inventor(s) include Dr. Sabincar Uvaraj Sreerama Chandar.
The application for the patent was published on Oct. 24, under issue no. 43/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to the processes for preparation of aqueous extracts of various parts of Neem to use them as effective herbal medicines. It particularly relates to the processes for preparation of purified aqueous extracts of stem bark, leaf, ' flower, fruit skin, white seed coat, seed kernel and root bark of neem containing a phenolic glycoside. Phenolic glycosides are antibacterial, antiviral, antifunga], natural antioxidants and therapeutic at low doses. The simple, easy, fast, and cheap single step unconventional methods were devised for the preparation of aqueous extracts of various parts of the neem. The aqueous extracts of the dried stem bark, leaves, flowers, fruit skin, white seed coat and root bark were prepared by soaking the known quantities of them in drinking water separately in the ratios of 1:1(w/v) and boiling the water for 5 minutes. Also, the aqueous extract of the dried seed kernel was prepared by soaking the known quantity of it in drinking water in the ratio of 1:3(w/v) and boiling the water for 5 minutes. The purified aqueous extracts of them containing phenolic glycoside were obtained by filiering the extracts along with the plant materials using separate tea filters. These aqueous extracts were analyzed by high performance liquid chromatography-mass spectrometry, UV visible absorption spectroscopy, infrared absorption spectroscopy and elemental analysis. These studies indicate that the aqueous extracts of stem bark, leaves, flowers, fruit skin, white seed coat, seed kernel and root bark were purified and contained a phenolic glycoside of molecular weight 498. These extracts can be stored at 40 C in refrigerator."
