Rauvolfia serpentine: History, Classification, Distribution, Morphological Features and Uses

Rauwolfia serpentina is said to appear in Sanskrit as an Ayurvedic medicine named Sarpgandha and Chandra. Sarpgandha, snakes smell or repellant refers to the use as an antidote for Snake-bite. Sen and Bose in 1931 reported the Rauwolfia serpentina valuable and safe in the treatment of High blood pressure “almost to a precision not found possible with any other drug, Eastern or western”. In 1949 Vakil concluded that, after extensive trials of various hypotensive remedies in several thousand cases of hypertension, in both private and hospital practice during the previous ten years, He found Rauwolfia serpentina to be the most successful drug and maintain a definite place in medicine because Rauwolfia serpentina lowered both systolic and diastolic blood pressure and It was non-toxic, with only mild toxic effects.

Papaya Carica’s Traditional and Medical Uses

The fruit of the solitary species in the genus Carica of the plant family Caricaceae is the papaya, often known as papaw or pawpaw. It is indigenous to the Americas’ tropics. A big, tree-like plant, the papaya has a single stem that can reach heights of 5 to 10 m (16 to 33 ft) and is covered in spirally arranged leaves only at the top of the trunk. The leaves are enormous, 50–70 cm in diameter, and have seven lobes that are deeply palmately lobed. Unless lopped, the tree is often unbranched. The leaves axils sprout blooms, which develop into substantial fruit. When the fruit is tender to the touch and has an amber to orange tint on its skin, it is ripe. These papaya nutritional benefits aid in stopping the oxidation of cholesterol. In addition to being a strong source of vitamins A, B, and G and vitamin C, papaya is also high in iron and calcium (ascorbic acid). Terpenoids, alkaloids, flavonoids, carbohydrates, glycosides, saponins, and steroids can be found in unripe C. papaya extracts.

Papaya: Classification, Distribution, Botanical Description, and Uses

The fruit of the papaya plant, Carica papaya, popularly known as papaw or pawpaw, is the sole member of the plant family Caricaceae with chromosome number 18. (Martelleto et al 2008). The red- and pink-fleshed varieties of the Carica papaya are referred to as papaya in Australia, whereas the yellow-fleshed varieties are called pawpaw. The plant is known as papaya in India (Dhillon 2013). It is indigenous to America’s tropics. One of the most significant economic crops in the tropics and subtropics is papaya (Reddy and Gowda 2014). Despite being a tropical fruit, it may also be cultivated in sub-tropical environments (Allan 2002, Galan and Rodriguez 2007). A fruit crop with a brief lifespan that can reach a height of 30 feet is the papaya. The stem is hollow and typically unbranched with softwood. Long stalked, palm-like leaves are present. Fruit from a pistillate flower has an ovoid-oblong form. The fruit is a berry with flesh. Smooth and green when unripe, papaya skin turns yellowish or orange when fully ripe. Orange or reddish-orange, the centre cavity is five-angled. The seeds are round, wrinkled, and black or greyish. The gelatinous sarcotesta is made of the exterior integument (Kumar et al 2013). Although papayas are hermaphrodite, they can also be dioecious. It is a well-liked crop among farmers, and there is a steady market demand for the fruits. It is a highly lucrative crop that has a favourable cost-benefit ratio (Sharma and Zote 2010). Papaya growth stops in subtropical climates at temperatures below 11 °C (Allan et al 2002). Therefore, papaya growing under protection in a subtropical area might offer the best conditions for the fruit’s development and productivity. With the important additional benefit of the Ring spot virus being excluded, growth and blooming benefits from the environment within the enclosed chambers result in improved yields, both in fruit quality and quantity (Galan and Rodriguez 2007). Determining papaya productivity and quality characteristics under protected agriculture is therefore crucial.

Khaya anthotheca: Origin, Classification, Characteristics, and Uses

Khaya anthotheca, a member of the Meliaceae family, has six species, four of which are found in equatorial Africa and two each in Madagascar and the Comores (Wiselius, 1998). The paripinnate leaves and mostly spherical, 4-5 valved, dehiscent woody capsules of this genus make it simple to identify. Numerous trial plantations in Indonesia and Peninsular Malaysia introduced Khaya members (Wiselius, 1998). Khaya species are tall, with cylindric boles, and are naturally fast-growing. It is virtually always grown in homesteads across Bangladesh, primarily in the country’s southwestern regions. It was impossible to identify due to a paucity of fruiting and flowering plants. Its flowering and fruiting specimens were taken from Jessore in 2009.

Blackboard Tree: Classification, Distribution, Characteristics, and Uses

Alkaloids, coumarins, flavonoids, leucoanthocyanins, reducing sugars, simple phenolics, steroids, saponins, and tannins are all frequently found in the A. scholaris plant. Eight elements, including Cu, Zn, Fe, Ca, Cr, Mn, and Cd, are present in the leaf extract. Four picrin type monoterpenoids—5-methoxyaspidophylline, picrinine, picralinal, and 5-methoxystrictamine—are present in the ethanolic extract of leaves.

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.
