Laurales order

Alkaloids of the Anonace. This botanical family belongs to the natural order Anonales, which is nearly related to the Laurales, in which are included the families Lauraeeas and Monimiaeeas. It is not surprising, therefore, that the characteristic alkaloids found in these families are of one type, namely derivatives of aporphine. 

Caryophyllidae are an interesting source of oligosaccharides and peptides with potential anti-inflammatory and/or immunomodulating effect. These polar compounds might for instance explain the fact that the fresh juice expressed from Aerva lanata (L.) Juss. (Amaranthaceae) inhibits carrageenan-induced edema in rodent. Note that the seeds of Gomphrena species inhibit the formation of IL-6 by osteoblastic cells (MC3T3-E10) without cytotoxicity in vitro. Such property could be useful for the treatment of chronic rheumatoid arthritis, infection, and cancer. In the Lauraceae, trans-cinnamal-dehyde from Cinnamomum cassia (Lauraceae, order Laurales) inhibits in vitro the... 

The family Hernandiaceae consists of four genera Hernandia, Illigera, Gyrocarpus, and Sparattanthelium, and about 60 species of trees, shrubs, and woody climbers widespread in tropical regions. An example of Hernandiaceae is Hernandia ovigera L., which is grown as a tropical street tree. Hernandiaceae are member of the order Laurales and are known to abound with aporphines and lignans. 

Savolainen et ak proposed a division of the angiosperms into two major groups the eudicots (particularly asterids and rosids) and the noneudicots (monocots and Laurales, Magnoliales, Piperales, Ceratophyllales, Amborellaceae, Nymphaceae, Liliaceae). ACS isozymes used in the analysis are presented in the order proposed by molecular systematicians.

In this chapter, we present a newflower from the Early Cretaceous (Early-Middle Albian) Puddledock locality, Virginia, USA. We also formally describe a second lauralean floral structure from the same locality that was briefly considered in an earlier publication (Crane et al., 1994). Both taxa have features characteristic of extant Laurales, but provide new evidence of the floral diversity among lauralean lineages from the Early Cretaceous and thereby contribute to a better understanding of the early evolution of the order. 

The Myristicaceae family belongs to the order Laurales and includes 19 genera (Table II), sbc of which are native to the American Continent. According to the vouchers that are kept in the Colombian National Herbarium, 50 species of these seven genera have been collected in our country, as shown in Table III.
