Pittosporum viridiflorum Sims (Pittosporaceae): A review on a useful medicinal plant native to South Africa and tropical Africa

“…The Pittosporaceae is a small family of flowering plants containing nine genera, with approximately 200-240 species largely restricted to Australia and limited to the paleotropics (Chandler et al, 2007;Sadashiva et al, 2013;El Dib et al, 2015). Seven of the Pittosporaceae genera are endemic to Australia, Indonesia and the Philippines .…”

“…The family has a wide range of habitats, from areas of great aridity, such as the Australian Nullarbor Plain, to wet montane areas of Queensland, New Caledonia and Hawaiian Islands, as well as alpines in New Zealand (Gemmill et al, 2002). From an economic perspective, Hymenosporum and Pittosporum are the two most commonly known Pittosporaceae genera, and they are used as cultivated ornamentals (El Dib et al, 2015). Australia is represented as the centre of prominence for Hymenosporum, however the genus also has a representation in New Guinea (Chandler et al, 2007).…”

“…In addition to the Australian distribution of Pittosporum, the genus may be found in Africa, Asia, and the Hawaiian Islands (Chandler et al, 2007). It contains approximately 140-200 species comprising trees or shrubs that grow 2 to 30 m in height, and occasionally epiphytes (El Dib et al, 2015). The genus is Gondwanan, and its current distribution is in tropical and subtropical regions in Africa, Asia, New Zealand, Pacific Islands and Australia .…”

“…Pittosporum is reported to be the only genus of the family present in Malagasy flora (Friis, 1987). The species of this genus are commonly known as "cheesewood" (El Dib et al, 2015). In Africa and Arabia Pittosporum is reported to be divided into 24 species (Friis, 1987).…”

Characterization of the complete chloroplast genome and phylogenetic analysis of Pittosporum tobira (Pittosporaceae)

“…Pittosporum tobira contains many bioactive substances, including phenolic acids, flavonoids, terpenoids, and other metabolites. These compounds are synthesized by different parts (leaf, root, seed, flower, and stem bark) of this species (Fan et al 2011) and exert many biological effects including anti-thrombogenic, anti-microbial, anti-hemolytic, cytoprotective and antioxidant proprieties (Ogihara et al 1989;Nickavar et al 2004;Oh et al 2014;El Dib et al 2015;Rjeibi et al 2017). To better understand the applications of P. tobira, the complete chloroplast (cp) genome of this species was sequenced and analyzed using highthroughput sequencing technology.…”
