"Chemicals from Cacti and Other Succulents"

Presented by Dr. Art Friedman

here to watch the presentation of the meeting on video

Note the meeting location:

Sky Islands Public High School, 6000 E. 14th Street, Tucson, AZ 85711

There are an estimated 391,000 known plant species of which fewer than 10,000 are succulents. The number of known chemicals exceeds the number of plants by nearly three orders of magnitude. In this presentation, Dr. Art Friedman will examine a group of cacti and succulents from a chemical perspective, noting which plants contain compounds that are deadly poisons and which ones contain potentially life-saving drugs, as well as illegal controlled substances.

While no prior knowledge of chemistry is necessary (although it is helpful to have), a short discussion of how to interpret chemical structures will be provided and how these structures can be used to predict biological properties of the compounds in question.

"Dr. Art Friedman is a native of Philadelphia, but has lived and worked in the midwest for over 32 years. Art graduated from Drexel Institute of Technology with a B.S. in biological science, and after a few years of industrial employment returned to Drexel University where he received an M.S. degree in biochemistry and a Ph.D. in organic chemistry.

Although his career has been primarily evoted to R&D activities in the fields of pharmaceutical, agricultural and environmental chemistry, as well as teaching at both high schools and colleges, Art has also been involved in bringing the joy of chemistry to the masses for over 35 years. He created a program, "The Magic of Chemistry" that was seen by over 30,000 students in four states, and was featured on a nationally syndicated program "PM Magazine".

Art and his wife Erica, have resided in Tucson since January of 2018. He currently is offering a number of science classes through Pima County's Special Interest Programs."

Please come and enjoy knowing about the chemistry of cacti and other succulents. Talk with members and guests, have some fun, check out our library books and be sure to have the great refreshments. Win some plants and also, make it a point to stay until the end of the meeting and get your free plant offered by the TCSS.
