Hummingbird tree: Origin, Distribution, Classification, Characteristics, Phytochemical Constituents, and Uses

Agati, also known as Sesbania grandiflora, is a type of West Indian pea and a member of the Fabaceae family. It can be found in several Asian nations, including India, Malaysia, and Indonesia. A classic south Indian dish called Agathi keerai is made with Sesbania grandiflora flower. Sesbania grandiflora is used as a traditional medicine alone or in combination with other medicinal plants to treat a variety of illnesses and infections such as swellings, headaches, anaemia, bronchitis, liver disorders, pains, and tumours, among others. The leaves of this plant are used as an antidote for tobacco-related issues as well as to cure anaemia, itching, fever, respiratory diseases, diuretic, purgative, and anthelmintic symptoms. Tribals have long used flowers to treat a range of illnesses, including headaches, cataracts, and insomnia.
Sesbania grandiflora, often known as a vegetable hummingbird, is a small, erect-branched tree that belongs to the Fabaceae family and is an evergreen or deciduous perennial legume. It is a rapidly growing, short-lived, firewood tree with few branches. Due to these species’ high nitrogen fixation capacities, Sesbania is used as green manure, intercropping, and ground cover in agroforestry and wood production systems, which promotes rapid development even in soils with low nitrogen levels. Studies have shown that S. grandiflora leaves are very nutrient-dense and include considerable amounts of proteins, fats, carbs, fibre, and minerals like calcium, phosphorus, and iron. Young leaves can be eaten and are frequently added to meals. In addition to essential amino acids, minerals, and vitamins (retinol, tocopherol, ascorbic acid, thiamine, riboflavin, and nicotinic acid), leaves also contain pectin, triterpenoids, tannin, glycosides, grandiflorol, and saponins. Flavonoids include catechin, epicatechin, quercetin, myricetin, kaempferol, and luteolin.

Persian Silk Tree: Distribution, Classification, Characteristics, Phytochemical Constituents, and Importance

Phytochemical Significance of Persian Silk Tree
Studying the phytochemistry of various Albizia species revealed various kinds of secondary metabolites, including saponins, terpenes, alkaloids, and flavonoids. Triterpenoid saponins (julibroside J29, julibroside J30, julibroside J31), novel macrocyclic alkaloids (budmunchiamines A, B, and C), and two flavonol glycosides (quercitrin and isoquercitrin) were some bioactive compounds isolated and identified from the genus Albizia. These compounds demonstrated various biological activities, including antitumor, and antiplatelet Anthraquinone glycosides, which cause the leaking of cytoplasmic components, were the anthraquinone elements of A. lebbeck bark extract that were active.

Callisia fragrans: Classification, Characteristics, Distribution, Chemical Constituents, and Medicinal properties

A cultivated perennial herbaceous succulent called Callisiafragrans (Olennikov et al., 2008). A variety of biologically active substances, including phenolic, flavonoid, coumarin, anthraquinone, triterpene, alkaloid, choline, and fatty acids, are present in the leaves of C. fragrans. These substances include carbohydrates, ascorbic acids, amino acids, and ascorbic acid (Chernenko et al., 2007; Nguyen and Trinh, 2019). Callisia fragrans has been shown to have radioprotective, hypersensitivity, antihypoxic, antiherpetic, and other therapeutic characteristics that are good for the liver, pancreas, gastrointestinal tract, skin, and bronchial asthma (Ludmila et al., 2010; Mairapetyan et al., 2014; Susan et al., 2006; Malakyan et al., 2015; Thom et al., 2018)

Ruellia tuberose: Classification, Distribution, Characteristics, Chemical Constituents, and Uses

Ruellia tuberose L. Leaves include luteolin and apigenin. Capril, myristic, and lauric acids are produced from seed oil. The study produced secondary metabolites, good-quality nutrients, flavonoids, glycosides, phenols, saponins, and important minerals.
It has been claimed that the plant contains phytochemicals including coumarin, phenolic compounds, oleic acid, methyl esters, steroids, terpenoids, long-chain aliphatic compounds, and flavonoids, among others.

Reproduction in Animals: Question and Answers CBSE/NCERT For  Class 8th Chapter 9

Define test-tube baby?
Ans: In-vitro fertilisation, or IVF, is a method used by women who have blocked oviducts and are unable to conceive naturally to create a test-tube baby. For IVF (in vitro fertilisation), doctors take freshly released eggs and sperm and keep them combined for a few hours (fertilisation outside the body). The zygote is given a week to develop if fertilisation occurs before being inserted into the mother’s uterus. Like any other infant, the baby grows completely inside the uterus before being born. Test-tube babies are those born in this manner. This is a misleading term because babies cannot develop in test tubes.

Dendrobium: Distribution, Characteristics, Plant Morphology, Growth, and Flowering

It is found throughout many tropical and subtropical areas, including Southeast Asia, where there are hundreds of species, and Vietnam, where there are over 100 species, all of which are extensively dispersed. With more than 16,000 species, Dendrobium is the second-largest orchid genus (Puchooa, 2004). Major producers of Dendrobium orchids include Thailand, Taiwan, China, the Philippines, Germany, the United States, Japan, and India. The majority of Dendrobium species are epiphytic, sympodial orchids that are native to subtropical and tropical areas. This genus is well-known for its ability to produce cut flowers. Commercial Dendrobium cultivation is widespread in the states of Karnataka, Kerela, Tamil Nadu, and Andhra Pradesh.

Ixora coccinea: Classification, Origin, Characteristics, Phytochemistry and Traditional Uses

Ixora coccinea Linn. (Rubiaceae), sometimes called red ixora, scarlet ixora, jungle of geranium, jungle flame, flaming love, and flame of the woods. The species name “coccinea” means crimson, while the genus name “Ixora” is thought to come from the Sanskrit word “ikvana,” which is named after a Malaysian deity. It may also be derived from the term “Iswara,” which is another name for Lord Shiva, to whom the flowers are dedicated during worship. All plant parts have been shown to have medicinal value in Ayurveda, the conventional Indian medical system, as well as in several indigenous medical systems in Sri Lanka and India. The plant produces chickpea-sized red to scarlet coloured fruits that are also eaten as food, particularly by Indian villages and tribal communities’ young inhabitants. There are over 500 species of tropical evergreen trees and bushes there. Ixora is a plant that is frequently found in subtropical regions of the United States, including Florida. Only a small number of the about 500 species in the genus Ixora are regularly grown in gardens.

Monkeypox virus: Disease Agent, Background, Characteristics, Common Human Exposure Routes, and Treatment

A member of the genus Orthopoxvirus, which also includes camelpox, cowpox, vaccinia, and variola viruses, is the monkeypox virus. The World Health Organization confirmed in 1980 that the virus is the main orthopoxvirus infecting human populations since smallpox elimination. In the resource-limited endemic regions where monkeypox is found, clinical detection, diagnosis, and prevention still pose difficulties. Studies carried out before the conclusion of smallpox eradication provide information on monkeypox epidemiology, but additional evaluations are required now that routine smallpox vaccination has finished and there is associated declining herd immunity. To further inform preventative strategies and gain a better understanding of the animal species involved in virus transmission and maintenance, basic ecological studies are also required
