Pyrostegia venusta (Ker Gawl.) Miers: A Botanical, Pharmacological and Phytochemical Review

Abstract

Pyrostegia C. Presl (Bignoniaceae) is a genus of four species. All four species are native to South America [3]. Pyrostegia venusta (Ker Gawl.) Miers, a popular ornamental, is cultivated throughout the tropics, and is native to the Brazilian Cerrado, and popularly known as "cipó-desão-joão. " [3,4]. In the traditional Brazilian medicine, the aerial parts of Pyrostegia venusta are used as infusion or decoction and administered orally as a general tonic, as well as a treatment for diarrhoea, vitiligo, cough, and common diseases of the respiratory system related to infections, such as bronchitis, flu and cold [4,5]. The literature records the isolation of oleanolic acid from both the aerial parts and flowers of Pyrostegia venusta [6]. Oleanolic acid proved to be biologically very important. It has cytotoxic, antitumer, antioxidant, anti-inflamatory, anti-HIV, acetyl cholinesterase, alphaglucosidase, antimicrobial, hepatoprotective, anti-inflammatory, antipruritic, spasmolytic activity, anti-angiogenic, antiallergic, antiviral and immunomodulatory activities [7]. Also, the compounds acacetin-7-O-β-glucopyranoside and β-sitosterol isolated from flowers, roots and aerial parts of Pyrostegia venusta [6,8,9], showed anti-inflammatory activity [10,11]. These results highlight the possible promising activities of Pyrostegia venusta. Botanical Characterizations Pyrostegia species are lianas; the most reliable way to identify Pyrostegia venusta is by the disposition of the leaves, the type of inflorescence, the level of the staminode insertion, and the characteristics of the fruits, which according to Pool [3].

Agronomic descriptors and ornamental potential of passion fruit species

“…Miers is a plant of the family Bignoniaceae, native to the Brazilian Cerrado, popularly known as "cipó-de-são-joão" (MOSTAFA, 2013). This species has physiological characteristics distinct from those of Passiflora, but it is a morphologically similar climbing plant, presenting tendrils, woody branches, trifoliate leaves, and with capacity of shading, being commonly used in ornamentation.…”

Cryopreservation of Pyrostegia venusta (Ker Gawl.) Miers seeds

“…Although P. venusta is generally cited as an invasive plant and weed in pastures, the species is a popular ornamental, cultivated for landscaping due to its lush inflorescences that hold striking orange tubular flowers (Oliveira & Wendling 2013, Online Compendium Gerson Luiz Lopes 2018, Plantamed 2018. In Brazilian folk medicine, aerial parts and flowers of the plant are used in infusions or decoctions and administered orally as a general tonic, as well as for the treatment of diarrhea, vitiligo, cough and common infectious diseases of the respiratory system such as bronchitis, flu and cold (Ferreira et al 2000, Mostafa et al 2013. Pharmacological studies, analyzing hidroethylic extracts of flowers, aerial parts and roots successfully isolated biologically active compounds oleanolic acid, acacetin 7-O-β-glucopyranoside and β-sitosterol, with anti-inflammatory, antitumor, antioxidant, antimicrobial and anti-HIV, antiallergic and immunomodulatory properties (Veloso et al 2010, Mostafa et al 2013, Figueiredo et al 2014, Moreira et al 2015.…”

Computer-Based Pharmacognosy: A Review

“…Pharmacognosy is a developing science that started by dealing with morphology and taxonomy of crude drugs, then it focused on isolation, quantification and structure elucidation of active compounds [7][8][9], these phytochemicals may have potential protective or disease preventive properties [10,11], essential oils characterization [12][13][14], and recently the term Reverse Pharmacognosy has evolved by concerning with the potential biological activity of a crude drug or its isolated compounds. This can result in the discovery of novel lead compounds or new biological activities [7,15].…”
