[28] | 2014 | Italy | PD | Drosophila melanogaster model (fruit fly) | Not applicable | Suggesting that its effects cannot only depend upon its leva-dopa content but support the clinical observation of MPE as an effective medication with intrinsic ability to delay the onset of chronic leva-dopa-induced long-term motor complications |

| 8 | Yadav et al. [31] | 2013 | India | PD | Swiss albino male mice weighing 25 ± 5 gram | 25, 50,100, 150, and 200 mg/kg body-wt | Significantly reduced the PQ induced neurotoxicity as evidenced by decrease in oxidative damage, physiological abnormalities, and immunohistochemical changes in the parkinsonian mouse |
| 9 | Lieu et al. [32] | 2012 | USA | PD | Fourteen adult (6–9 kg) rhesus (Macaca mulatta) and two cynomolgus (Macaca fascicularis) monkeys | MPEP + CD (4.5 g/25 mg) | Distinctive neurophysiological findings in the basal ganglia and the ability to ameliorate parkinsonism without causing dyskinesias |
| 10 | Lieu et al. [33] | 2010 | USA | PD | Female Sprague-Dawley rats (250–400 g) | 80 mg/kg MPE (group 2), and 40 mg/kg MPE (group 3) with 15 mg/kg of BZ (MPE + BZ) | MP contains water-soluble ingredients that either have an intrinsic DDCI-like activity or mitigate the need for an add-on DDCI to ameliorate parkinsonism |
| 11 | Dhanasekaran et al. [34] | 2008 | USA | PD | Male Sprague-Dawley rats (200–225 g) | Varying doses with different combinations | Inhibited the oxidation of lipids and deoxyribose sugar by exhibiting antioxidant and metal chelating effects |
| 12 | Tharakan et al. [35] | 2007 | USA | PD | Male Sprague-Dawley rats (200–225 g) | Varying doses with different combinations | MPCP has shown anti-parkinson and neuroprotective effects in animal models of PD that are superior to synthetic levo-dopa. The copper chelating property may be one of the mechanisms by which MPCP exerts its protective effects on DNA |
| 13 | Manyam et al. [36] | 2004 | USA | PD | Sprague-Dawley rats | 2.5, 5.0, or 10.0 g/kg/day | Antiparkinson effect may be due to components other than levo-dopa or that it has a levo-dopa enhancing effect |
| 14 | Majekodunmi et al. [9] | 2011 | Nigeria | Diabetes | Wistar rats (180–240 g) and albino mice (16–20 g) of both sexes | Methanol and ethanol fractions of MP | A single dose of the ethanolic extract of MP resulted in a significant reduction in the blood glucose level, reducing the weight loss associated with diabetes |
| 15 | Rathi et al. [37] | 2002 | India | Diabetes | Rats | 100, 200, and 400 mg/kg/day | MP had no significant effect |
| 16 | Choowong-In et al. [38] | 2021 | Thailand | ED | Ninety-six adult male (n = 48) and female (n = 48) ICR mice (10 weeks, weighing 35–40 g) | 600 mg/kg | Improve the sexual performances and reproductive parameters especially functional proteins in testis, epididymis, and sperm |
