Pharmacological activities

Pharmacological activities of Kalanchoe pinnata are shown in Figure 1 and discussed in details following are

Antihypertensive activity

This research examined the effects of aqueous leaf extract of K. pinnata on the blood pressure of anaesthetized cats, as well as the liver and kidney function of the rabbit. The findings indicated that the extract lowered the anaesthetized cat's blood pressure somewhat and also mitigated the impact of adrenaline-induced hypertension. This research demonstrated the pharmacological foundation for the Igbos of Nigeria's usage of K. pinnata to reduce blood pressure. However, the fact that the blood pressure decrease is minimal and the K. pinnata leaf extract may be harmful to humans precludes its usage as a blood pressure reducing agent.21

Hepatoprotective activity

In the folk medicines of India's Bundelkhand region, the juice of fresh leaves is extremely useful for curing jaundice. The ability of the leaves' juice and the ethanolic extract of the marc left over after expressing the juice to protect against CCl4-induced hepatotoxicity was evaluated in rats. In vitro, in vivo, and histology studies revealed that the test chemical was hepatoprotective. The juice was shown to be more effective than the ethanolic extract.22

Antimutagenic activity

Antihistamine and antiallergic effects are found in the plant. Methanol extract from the leaves has also been found to inhibit histamine receptors (H1) in the ileum, peripheral vasculature, and bronchial muscle, thus guarding against chemically induced allergic reactions and death by selectively inhibiting histamine receptors in the lungs. Quercetin-3-o—Larabinopyranosyl (12) Obaseiki- Ebor et al. found that organic solvent extracts of leaves inhibited His — to His + reverse-mutations caused by ethyl methanesulfonate acting on S. typhimurium TA100 or TA1002, as well as reversions caused by 4nitro-o-phenylenediamine and 2-aminofluorene in TA98. The alkaloidal/water soluble and acid fractions have no apparent antimutagenic efficacy.23

Anti-ulcer activity

In this research, the incidence of ulceration and mean basal and histamine induced stomach acid production were significantly reduced in a dose-dependent manner, supporting its usage as an anti-ulcer drug in traditional medicine.24

Antidiabetic activity

The presence of zinc in the plants may indicate that they could be useful in the treatment of diabetes caused by insulin dysfunction. The antinociceptive effect of the herb's aqueous leaf extract was tested in mice using the 'hot-plate' and 'acetic acid' pain models. Fresh egg albumin-induced pedal oedema and streptozotocin-induced diabetes mellitus were used to test the plant extract's anti-inflammatory and anti-diabetic properties in rats. In mice, the aqueous leaf extract had substantial antinociceptive effects (P0.05-0.001) against thermally and chemically generated nociceptive pain stimuli.

In rats, the plant extract reduced fresh egg albumin-induced acute inflammation and caused substantial hypoglycemia (P0.05-0.001). The herb's flavonoids, polyphenols, triterpenoids, and phytosterols are thought to be responsible for the plant's antinociceptive, anti-inflammatory, and antidiabetic effects. It is thought to have antinociceptive and anti-inflammatory properties by reducing the release, synthesis, and/or production of inflammatory cytokines and mediators such as prostaglandins, histamine, polypeptide kinins, and others.25

Uterine contractility

The phytotherapeutic tocolytic action of in human myometrium in vitro against the standard betamimetic, fenoterol Contractility was assessed in strips of term myometrium biopsied at caesarean section and subjected to escalating concentrations of B.Pinnatum vs +/- oxytocin 1 U/l in 14 women. The suppression of spontaneous contraction in the result state was concentration dependant. B. Pinnatum raised contraction frequency by 91% at constant amplitude while inhibiting oxytocin-stimulated contractions by 20% at constant amplitude but with a somewhat lower frequency. Fenoterol reduced contraction by 50% with a substantial reduction in frequency.26

Wound-healing activity

The ethanolic extract of K. pinnata demonstrated substantial wound-healing activity by reducing the size of the affected region and oedema at the wound site. This may be because steroidal glycosides and phenolic antioxidants are present.27 Water, petroleum ether, and alcoholic extracts of the plant were shown to have the ability to cure wounds in a research. Water extract was likewise shown to be more active than the other two extracts in the research.28

Antioxidant activity

The leaves were reported to show maximum scavenging effects than stems and the ethanolic extract showed more total phenolic and flavonoid content than other extracts. The high amount of phenols and flavonoids in the extracts may be the reason for their high antioxidative activity (Bhatti et al., 2012). The phenolic constituents have the ability to interact with the transition metals even in lipid phase and chelate them by filling their aqua-coordination sites and generating metal-coordinated insoluble complexes. Inhibition of lipid auto-oxidation could be attributed to the ability of phenolics to stabilise the radicals through generation of stabilised phenoxyl radicals by directly scavenging peroxyl radicals.29

Antitumour activity

Experiments were carried out on mice by causing tumour development in the peritoneal cavity. The plant's methanolic and aqueous extracts were used as medicines in precise doses. As a tumor-suppressing drug, these extracts reduced the amount of ascitic fluid and halted tumour development. As a result, the extracts were said to have antitumor action.30

The plant's anticancer properties was investigated. The intake of the aqueous extract for N-diethylnitrosamine (DENA)-induced hepatocarcinogenesis in rats reduced liver damage, according to the findings. The protective effect may be attributed to antioxidant and antiperoxidative properties, as well as the capacity to rectify anomalies in lipid and lipoprotein metabolism by increasing the activity of a few lipid metabolising enzymes. DENA's metabolism in the liver tends to produce free radicals, disrupting antioxidant status and eventually contributing to oxidative stress and carcinogenesis, which is why it's classified as a significant environmental hepatocarcinogen. Histopathological study of DENA-treated rats' liver sections revealed severe centrilobular necrosis and vacuolisation. The aqueous extract neutralised free radicals, decreased necrosis, and protected hepatocytes against DENA's carcinogenic effects.31

Antiviral activity

The anticancer and anti-HPV properties of the plant's chloroform extract were investigated in a research. When the extract fractions were applied to cancer cell lines, they inhibited the production of viral proteins, limiting both viral and tumour development. The Epstein-Barr virus is a herpes virus that infects human B-lymphocytes, causing tumours to develop32

Antimicrobial & antifungal activity

The antibacterial activity of K. pinnata was investigated, and it was shown that the methanolic extract had a higher inhibition rate. Bacteria that cause skin infections may also cause respiratory illnesses, food poisoning, wound infections, abscesses, osteomyelitis, endocarditis, pneumonia, and other problems when they enter the body. As a result, the produced extract may fight such illnesses and save the lives of those who are afflicted. The information provided may be utilised to create a commercial antibacterial and antifungal cream.33

Antileishmanial activity

Leishmaniasis is caused by protozoans of the genus leishmania. Mice infected with leishmania amazonensis were administered an aqueous extract of K. pinnata. Following the experiment, a few findings were recorded, including the lesions shrinking in size and the parasitical load in the affected region. Continuous treatment with the extract not only slowed the development of the bacteria, but also stopped them from spreading. This technique may potentially be used to treat visceral leishmaniasis, according to some.34

Insecticidal activity

The methanolic extract of K. pinnata yielded two bufadienolides. The inclusion of the 1, 3, 5-orthoacetate moiety of the bufadienolides was shown to be responsible for the isolated compounds' significant insecticidal action against silkworm third instar larvae.35

Antipyretic activity

The impact of plant extract on hyperthermic conditions in experimental animals was shown. Brewer's yeast was used to cause pyrexia in rats.When K. pinnata hydroalcoholic extract was given to laboratory specimens, it lowered body temperature, demonstrating its antipyretic activity. This action may be due to the presence of flavonoids in the extract.36

Antilithiatic activity

Calcium oxalate stones develop when oxalate excretion in the urine is decreased. On the basis of medical prophylaxis, fresh juice produced from the leaves of K. pinnata was given to patients with stones in their bodies. The juice, when consumed on a regular basis, successfully dissolved the stones, regardless of their location, nature, or prior treatments. The amount of urine voided increased, demonstrating the juice's diuretic properties. It also aided in the reduction of oxalate excretion while boosting citrate excretion. According to this research, the juice may have antilithiatic effects.3

Antibacterial activity

Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella aerogenes, Escherichia coli, Klebsiella pneumoniae, and Salmonella typhi are among the bacteria that cause typhoid fever and other bacterial illnesses, according to reports.Antibacterial activities of the infusion and methanolic extracts against S. aureus ATCC 13709, E. coli ATCC 9637, Bacillus, P. aeruginosa, K. pneumonia, and S. typhi were investigated using the agar diffusion process, as well as adjacent to S. aureus, E. coli, S. typhi, Klebsiella spp., and P. aeruginosa using.39, 40

Cytotoxic to cattle

The effects of cardiac glycoside poisoning in calves fed flower heads of hybrid Bryophyllum species were studied, and it was discovered that for each plant (except Bryophyllum tubiflorum), two calves were given a single dosage of 20 g wet weight per kg body weight.

The findings of the calf toxicity experiment, together with the quantities of bufadienolide found in the plants, indicate that bryotoxins A, B, and C are most likely to blame for the illness.41

Herbal tonic

Ascorbic acids, riboflavin, thiamine, and niacin are all abundant in the plant.Natural ascorbic acid is essential for body function, which includes the proper synthesis of intercellular components such as collagen, bone matrix, and tooth dentine throughout the body. As a result, the clinical symptoms of scurvy, such as bleeding from the mouth, gastrointestinal tract, anaemia, and joint aches, may be linked to the relationship between ascorbic acid and proper connective tissue metabolism.42

Cytotoxicity of testis

The cytotoxic impact of an ethanolic extract of B. pinnatum leaf on cells of the rat testis was investigated at two dosages (100 mg/kg and 200 mg/kg) given orally for eight weeks. When compared to the control group, which showed intact normal histological features of the testes, the seminiferous tubules shrank and intracellular spaces were seen within the epithelium at a dose of 100 mg/kg, and a higher dose (200 mg/kg) showed a marked increase in intracellular spaces within the germinal epithelium and a reduction of spermatozoa.43
