摘要:
A hybrid pigment composition is provided including a pigment or a dye and a fibrous clay. The pigment composition has higher reflectance in a near infrared region than a visible light region of the electromagnetic spectrum. The fibrous clay can be selected from palygorskite, sepiolite, and mixtures thereof. The hybrid pigment composition is tunable to provide high reflectance at a desired wavelength in the near infrared region.

摘要:
The use of extracts from Cryptolepis sp. or quinodoline alkaloids such quindoline and cryptolepine contained therein as hypoglycemic agents, as well as methods for obtaining the hypoglycemic agents are described. According to a preferred embodiment, the extracts are derived from Cryptolepis sanguinolenta. As hypoglycemic agents, the extracts or quindoline alkaloids such as quindoline or cryptolepine are useful for treating insulin-dependent (type I) and non-insulin-dependent (type II) diabetes.
