Generally, Unripe fruit of egg plant primarily used

Generally, the family is herbaceous or woody. Many plants in the family are
economically important. Products include potato and egg plants (Solanum species) and
tomato (Lycopersicon esculentum L.). Edible fruits can be found in the genus Physalis (Cape
gooseberry, Jam berry, Sugar jerry, Chinese Lantern etc.) according to the species and
variety. Capsicum (Sweet and chilli peppers). Etc. Most produce poisonous alkaloids and
some are commercially important in this connection (Nicotiana, Datura). The taxonomic
value of morphology is well documented in botanical literature, Dilcher (1974), Jayeola et
al., (2001), Adedeji and Faluyi (2001), Adeeji (2004) and Adedeji and Illoh (2004). Metcafe
and Chalk (1950) gave some description of the general morphology of the family Solanaceae.
Since then there has been no additional anatomical work on the family in Nigeria.
The Solanaceous food can be often found in our stores as potatoes, tomatoes and chilli
varieties, eggplant, and tomatillos. It was considered to be very valuable culinary vegetables.
The vegetable is used in both urban and rural areas, but since it is often bitter it is mixed with
Solanum species or with other green leafy vegetables. Many species of Solanaceae produce
tropane alkaloids that have valuable medicinal properties. Examples include Datura
stramonium, Datura fastuosa.
Nicotine is a tropane alkaloid. It makes a great insecticide. Example Nicotiana
tobaccum. The family also includes many ornamental species which include Cestrum species;
some others found as weeds. Examples include species of Solanum seaforthianum.
Potatoes contain toxic compounds known as glycoalkaloids, of which the most
prevalent are solanine and chaconine. Solanine is found in other plants of the
family Solanaceae, like the Black nightshade (Solanum nigrum), as well as the potato,
eggplant, and tomato.
Among the immature vegetables, Solanum melongena and Solanum tuberosum,
Capsicum frutescens, Capsicum annuum occupy a major area in cultivation in Tamilnadu.
The fruit of Solanum melongena known for its low calories has a beneficial mineral
composition for human health rich in source of Pottassium, Magnesium, Calcium and Iron
Gbile and Adesina (1984). Unripe fruit of egg plant primarily used as cooking vegetable Guri
et al., (1988) is grown as an annual crop. It has many medicinal values and its fruit helps to
lower the blood cholesterol levels, and is suitable as a part of a diet to help regulate high
blood pressure Goodspeed, (1933); Acosta et al., (2005).
The black nightshades family members are Solanum sisymbriifolium, Solanum
seaforthianum, Solanum torvum, Solanum nigrum, Withania somnifera and related species
are worldwide weeds of arable land, gardens, rubbish tips, soils rich in nitrogen, in
moderately light and’ warm situations which occur from sea to mundane levels. They are,
however, also widely used as leafy herbs and vegetables, as a source of fruit and for various
medicinal purposes.
Leaves and tender shoots are widely used and have provided a food source since early
times, with Solanum trilobatum being recorded as an ancient famine plant Acosta et al.,
(2006); Guerra, (2000). The leaves and young shoots are boiled or stewed and used as a
relish. They are also used in soups and sauces such as palaver.
