Lactuca Tenerrima

	Lactuca Tenerrima ''Lactuca tenerrima'' is a species of wild lettuce native to southern France, Spain, the Balearic Islands, and the Atlas Mountains of Morocco. Unlike other species in its genus ''Lactuca'', even in its family Asteraceae, it does not produce bitter-tasting sesquiterpene lactone Sesquiterpene lactones (SLs) are a class of sesquiterpenoids that contain a lactone ring. They are most often found in plants of the family Asteraceae (daisies, asters). Other plant families with SLs are Umbelliferae (celery, parsley, carrots) an ...s.

picture info	Lactuca ''Lactuca'', commonly known as lettuce, is a genus of flowering plants in the family Asteraceae. The genus includes at least 50 species, distributed worldwide, but mainly in temperate Eurasia. Its best-known representative is the garden lettuce (''Lactuca sativa''), with its many varieties. "Wild lettuce" commonly refers to the wild-growing relatives of common garden lettuce. Many species are common weeds. ''Lactuca'' species are diverse and take a wide variety of forms. They are annuals, biennials, perennials, or shrubs. Their flower heads have yellow, blue, or white ray florets. Some species are bitter-tasting. Most wild lettuces are xerophytes, adapted to dry habitat types. Some occur in more moist areas, such as the mountains of central Africa. Diversity There are different concepts of the species within ''Lactuca''. It is not clear how many distinct species are known, and estimates vary from 50 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Sesquiterpene Lactone Sesquiterpene lactones (SLs) are a class of sesquiterpenoids that contain a lactone ring. They are most often found in plants of the family Asteraceae (daisies, asters). Other plant families with SLs are Umbelliferae (celery, parsley, carrots) and Magnoliaceae (magnolias). A collection of colorless, lipophilic solids, SLs are a rich source of drugs. They can be allergenic and toxic in grazing livestock causing severe neurological problems in horses. Some are also found in corals such as '' Maasella edwardsi''. Types Sesquiterpene lactones can be divided into several main classes including germacranolides, heliangolides, guaianolides, pseudoguaianolides, hypocretenolides, and eudesmanolides. Examples Artemisinin, a new, highly-effective anti-malarial compound, is a sesquiterpene lactone found in ''Artemisia annua''. Lactucin, desoxylactucin, lactucopicrin, lactucin-15-oxalate, lactucopicrin-15-oxalate are some of the most prominent found in lettuce and spinach, giving ...
