Gudavalli D, Pandey K, Ede VG, Sable D, Ghagare AS, Kate AS. Phytochemistry and pharmacological activities of five species of Bauhinia genus: A review. Fitoterapia 2024; 174:105830. [PMID: 38286316 DOI: 10.1016/j.fitote.2024.105830] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 01/12/2024] [Accepted: 01/23/2024] [Indexed: 01/31/2024]
Abstract
Genus Bauhinia has been widely used in the treatment of diabetes, malaria, cough, headache, fever, piles, dysentery, flatulence, diarrhoea, ulcer and cardiovascular problems. Among 600 species of this genus, Bauhinia variegata, B. purpurea, B. championii, B. racemosa, and B. forficata are commonly used in the traditional medicine and found to be throughly investigated for their medicinal properties. They possess diverse pharmacological activities such as anti-diabetic, anti-microbial, antioxidant, anti-arthritic, cardioprotective, hepatoprotective, nephroprotective, fibrinolytic, and wound healing properties and most of the biological activities are corelating with traditional knowledge. Phytochemical analysis indicated that steroids, terpenoids, and flavonoids are prominent in the selected species, whereas bauhiniastatins, bauhinoxepins, racemosols, roseosides, and bauhichamines are found unique to the genus. This review aims to decipher active molecules from the aforementioned species of Bauhinia covering comprehensive analysis of phytochemistry, pharmacological activities and traditional uses. The data has been carefully analyzed to find compounds or fractions with a translational value. In most of the cases, the pharmacological activities have been established, however, further studies are needed such as safety evaluations, target identification, bioavailability, metabolite identification, and pharmacokinetic properties. In conclusion, the pharmacological potential of Bauhinia plants show promise with various leads such as insulin-like protein, roseoside, bauhiniastatin, and melibiose binding lectin. However, further investigations are required to address existing gaps and advance them towards product development. This review will lay the groundwork for future research initiatives aimed at fully realizing the therapeutic potential of Bauhinia plants.

Fortunato RH, Nores MJ. "Cow's Hoof" ( Bauhinia L., Leguminosae): A Review on Pharmacological Properties of Austral South American Species. PLANTS (BASEL, SWITZERLAND) 2022; 12:31. [PMID: 36616160 PMCID: PMC9823647 DOI: 10.3390/plants12010031] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 11/17/2022] [Accepted: 11/21/2022] [Indexed: 06/17/2023]
Abstract
The genus Bauhinia s.l. (Leguminosae), known as cow's hoof, unha de boi or pata de vaca, has been used in traditional medicine worldwide. The aim of the present review is to summarize the studies published on the biological activity of the main native medicinal species reported in austral South America. Of the 14 species present in the region, 10 are consumed as leaf infusions to regulate glucose and lipid metabolism, as well as used for their anti-inflammatory and analgesic effects and to treat various diseases. Pharmacological properties have been recorded in seven species. Antioxidant, anticoagulant, antihypertensive, diuretic, antimicrobial and antitumor properties have been reported in B. forficata. Together with B. holophylla, they are important for their antidiabetic properties, since several studies indicate their effectiveness as a hypoglycemic agent. B. bauhinioides is distinguished for its anti-inflammatory and antithrombotic activities and S. microstachya for its analgesic properties. Anti-ulcer and wound healing activities recorded in B. holophylla and B. ungulata, respectively, are of particular interest. Most of the species possess antitumor activity. The antioxidant capacity of flavonoids and other bioactive compounds make these plants good candidates to assist or treat various alterations related with oxidative stress, such as diabetic complications. Thus, these species constitute promising targets for new bioactive substance research and phytotherapy.

Abstract
In this study, we found that the total polyphenol and ascorbic acid levels in the fruit of Opuntia humifusa are higher than those in other parts of the plant. We further hypothesized that antioxidants in O. humifusa might affect the growth or survival of cancer cells. Hexane extracts of seeds and ethyl acetate extracts of fruits and stems significantly suppressed the proliferation of HeLa cervical carcinoma cells, but did not affect the proliferation of normal human BJ fibroblasts. Additionally, the extracts of O. humifusa induced G1 phase arrest in HeLa cells. The O. humifusa extracts reduced the levels of G1 phase-associated cyclin D1, cyclin-dependent kinase 4 (Cdk4), and phosphorylated retinoblastoma proteins. Moreover, p21(WAF1/Cip1) and p53 expression significantly increased after treatment. We examined the effects of ethyl acetate extracts of O. humifusa fruit (OHF) on HeLa cells xenograft tumor growth. OHF treatment significantly reduced tumor volume and this decrease was correlated with decreased Cdk4 and cyclin D1 expression. Furthermore, flavonoids, trans Taxifolin, and dihydrokaempferol, were isolated from OHF. Thus, this extract may be a promising candidate for treating human cervical carcinoma.

Abstract
Bauhinia forficata Link. is utilised as an antidiabetic in Brazilian folk-medicine; furthermore, its antioxidant properties suggest a potential usefulness in the prevention of diabetes complications associated with oxidative stress. The contribution of a flavonoid-rich fraction (FRF), HPLC-PDA-ESI-MS characterised, to the antioxidant and cytotoxic properties of B. forficata hydro-alcoholic leaves extract was evaluated for the first time. Both extract and FRF showed radical-scavenging activity and reducing power with a strong relationship with the flavonoid content found; hence, flavonoids are mainly responsible for the primary antioxidant activity of B. forficata extract. The extract significantly decreased FO-1 cell viability at the higher concentrations. FRF did not exert any effect; thus, flavonoids do not appear to be responsible for the cytotoxicity of the extract. The extract resulted virtually non-toxic against both Artemia salina and normal human lymphocytes, demonstrating potential selectivity in inhibiting cancer cell growth. Finally, no antimicrobial activity was observed against the bacteria and yeasts tested.

Effect of Syzygium cumini and Bauhinia forficata aqueous-leaf extracts on oxidative and mitochondrial parameters in vitro. EXCLI JOURNAL 2015; 14:1219-31. [PMID: 27152111 PMCID: PMC4849105 DOI: 10.17179/excli2015-576] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/17/2015] [Accepted: 11/23/2015] [Indexed: 11/10/2022]
Abstract
Aqueous-leaf extract of Syzygium cumini and Bauhinia forficata are traditionally used in the treatment of diabetes and cancer, especially in South America, Africa, and Asia. In this study, we analyzed the effects of these extracts on oxidative and mitochondrial parameters in vitro, as well as their protective activities against toxic agents. Phytochemical screenings of the extracts were carried out by HPLC analysis. The in vitro antioxidant capacities were compared by DPPH radical scavenging and Fe(2+) chelating activities. Mitochondrial parameters observed were swelling, lipid peroxidation and dehydrogenase activity. The major chemical constituent of S. cumini was rutin. In B. forficata were predominant quercetin and gallic acid. S. cumini reduced DPPH radical more than B. forficata, and showed iron chelating activity at all tested concentrations, while B. forficata had not similar property. In mitochondria, high concentrations of B. forficata alone induced a decrease in mitochondrial dehydrogenase activity, but low concentrations of this extract prevented the effect induced by Fe(2+)+H2O2. This was also observed with high concentrations of S. cumini. Both extracts partially prevented the lipid peroxidation induced by Fe(2+)/citrate. S. cumini was effective against mitochondrial swelling induced by Ca(2+), while B. forficata alone induced swelling more than Ca(2+). This study suggests that leaf extract of S. cumini might represent a useful therapeutic for the treatment of diseases related with mitochondrial dysfunctions. On the other hand, the consumption of B. forficata should be avoided because mitochondrial damages were observed, and this possibly may pose risk to human health.

Antimutagenic Effect of Medicinal Plants Achillea millefolium and Bauhinia forficata In Vivo. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:893050. [PMID: 24459532 PMCID: PMC3891236 DOI: 10.1155/2013/893050] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/30/2013] [Revised: 12/05/2013] [Accepted: 12/06/2013] [Indexed: 11/17/2022]
Abstract
The investigation of traditionally used medicinal plants is valuable both as a source of potential chemotherapeutic drugs and as a measure of safety for the continued use of these medicinal plants. Achillea millefolium L. (AM) is an ancient remedial herb native to Europe that is used to treat wounds, gastrointestinal and hepatobiliary disorders, inflammation, headaches, and pain. Bauhinia forficata Link (BF), an Asiatic plant, is one of the most commonly used plants in folk medicine against diabetes. The aim of this study was to evaluate the cytotoxic and antimutagenic potential of aqueous extracts of AM and BF on bone marrow cells of Wistar rats treated in vivo. These plant extracts possess considerable antioxidant activity due to the presence of flavonoids and phenolic compounds. These compounds were determinants to noncytotoxic and antimutagenic/protective action of these plants, that reduced statistically the percentage of chromosomal alterations induced by the chemotherapeutic agent cyclophosphamide in simultaneous (AM, 68%; BF, 91%), pre- (AM, 68%; BF, 71%), and post-treatment (AM, 67%; BF, 95%). Therefore, the results of this study indicate that extracts of A. millefolium and B. forficata have antimutagenic potential and that their consumption can benefit the health of those using them as an alternative therapy.

Abstract
WE DESCRIBE THE MEDICINAL PLANTS THAT HAVE BEEN REPORTED TO BE ANTITUMOR AGENTS AND THAT HAVE BEEN USED IN ETHNOBOTANIC RESEARCH IN BRAZIL TO ANSWER THE FOLLOWING QUESTIONS: what is the abundance of plants reported to be antitumor in Brazil? Have the plant species used for tumor treatment in traditional Brazilian medicine been sufficiently examined scientifically? Our analysis included papers published between 1980 and 2008. A total of 84 medicinal plant species were reported to be used for cancer and tumor prevention or treatment; 69.05% of these were cited as being used for the treatment of tumors and cancer in general and 30.95% for specific tumors or cancers. The plants that were cited at a higher frequency were Aloe vera, Euphorbia tirucalli, and Tabebuia impetiginosa. At least, one pharmacological study was found for 35.71% of the species. Majority of the studies selected were conducted in rural communities and urban areas and in areas with traditional healers in Brazil. We found the following molecules to be the most studied in vitro and in vivo: silibinin, β-lapachone, plumbagin and capsaicin. The species addressed here constitute interesting objects for future studies to various professionals in the field of natural products.

Abstract
Plants of the genus Bauhinia (Fabaceae, Leguminosae), commonly known as cow's-paw or cow's hoof, are widely distributed in most tropical countries and have been used frequently in folk medicine to treat different kinds of pathologies, particularly diabetes, infections, as well as pain and inflammation. In recent years, interest in these plants has increased considerably throughout the world. The biological properties of different phytopreparations and pure metabolites have been investigated in numerous experimental in vivo and in vitro models. Although some contradicting evidence has been documented, in general, the results support the reported therapeutic properties, indicating that they are mainly due to the presence of flavonoids. This review summarizes the recent chemical and biological knowledge of plants of the genus Bauhinia.

Abstract
Leaves of the pantropical genus Bauhinia (Fabaceae) are known popularly as cow's foot, due to their unique characteristic bilobed aspect. The species Bauhinia forficata (Brazilian Orchid-tree) is widely used in folk medicine as an antidiabetic. The present work investigates the hypoglycemic activity of the dried extracts of Bauhinia forficata leaves in vivo, as well as the influence of the drying and granulation processes on this activity. The fluid extract was dried to generate oven-dried (ODE), spray-dried (SDE) and wet granulation (WGE) extracts, with the aid of colloidal silicon dioxide and/or cellulose:lactose mixture. The dried extracts were characterized by spectrophotometric, chromatographic and photo microscopy image analysis. 200 mg/kg body wt., p.o. of each dried product were administered orally to male Wistar rats over 7 days old, for biomonitoring of the hypoglycemic activity profile. The effect of the extracts was studied in STZ-induced diabetic rats. After 7 days of treatment, fasting glucose was determined, and the livers were removed, dried on tissue paper, weighed, and stored at -20 degrees C to estimate hepatic glycogen. Our results show that spray-drying or oven-drying processes applied to B. forficata extracts did not significantly alter its flavonoid profile or its hypoglycemic activity. Indeed, the dried extracts of B. forficata act differently from glibenclamide. Despite the lower active content in WGE, because of the higher concentration of adjuvants, the use of the granulation process improved the manufacturing properties of the ODE, making this material more appropriate for use in tablets or capsules.

Abstract
In the course of screening for anticancer agents, a novel active compound, F3-2-5, was isolated from culture broth of Streptomyces sp., KACC91015. Its structure was identified using nuclear magnetic resonance, mass spectrometry, and molecular modeling experiments, and confirmed by total synthesis. The growth of various human cancer cell lines was inhibited in a dose-dependent manner by 0.06-0.48 mM F3-2-5 over 24 h. Its IC(50) values were estimated at 37 microM on HeLa, 72 microM on A549, and 190 microM on HT-29 cells. However, F3-2-5 had no antiproliferative effect on normal lymphocytes and normal fibroblasts used as controls. Moreover, it affected cell cycle regulation and caused apoptosis of the HeLa cells; chromatin condensation and DNA fragmentation were observed in cells exposed to 80 microM F3-2-5. Western blot analysis revealed that F3-2-5 inhibited phosphorylation of retinoblastoma protein (pRb) and reduced expression of cyclin-dependent kinase-4 and -6, and cyclin D1 and E, while levels of p53 and p21(WAF1/CIP1) increased. Taken together, these findings show that F3-2-5 inhibits proliferation of HeLa cells by inducing G(1) phase arrest as a consequence of inhibition of pRb phosphorylation following up-regulation of p21(WAF1/CIP1) and p53. Furthermore, apoptosis in HeLa cells treated with F3-2-5 was associated with an increase in Bax and p53, leading to release of cytochrome c, activation of caspase-3, and -8, and cleavage of poly (ADP-ribose) polymerase.
