Introduction


 

Moringa oleifera is the most widely cultivated pan-tropical species of a monogeneric family, the Moringaceae, which is native to the sub-Himalayan tracts of India, Pakistan, Bangladesh and Afghanistan. Moringa oleifera is known by such regional names as benzolive, drumstick tree, kelor, marango, mlonge, mulangay, nébéday, saijhan, and sajna.1. Virtually every part of the tree is beneficial in some way and both rural and urban people depend on it for their livelihood. In developing tropical countries, Moringa trees have been used to combat malnutrition, especially among infants and nursing mothers 2,3. The leaves of the Moringa tree are an excellent source of Nutrients like Minerals, Protein and Vitamins (A and C) 4, 5, 6, Moringa has approximately 46 antioxidants and is one of the most powerful sources of natural anti-oxidants. Anti-oxidants supply the free atoms needed by the human body and mitigate the effect of free radicals. M. oleifera contains active compounds such as flavonoids, tannins, saponins, alkaloids, phenolics, and triterpenoids which possess antibacterial effects.7

Medicinal usus of Moringa oleifera 

Moringa has approximately 46 antioxidants and is one of the most powerful sources of natural anti-oxidants. Anti-oxidants supply the free atoms needed by the human body and mitigate the effect of free radicals. M. oleifera contains active compounds such as flavonoids, tannins, saponins, alkaloids, phenolics, and triterpenoids which possess antibacterial effects hence it can be used as safe and cheap plant antimicrobial agent. The extract from leaves of Moringa oleifera has high mineral and protein content and its historic reputation as a traditional medicine for different diseases has been previously investigated for its potential in treating different oral soft tissue diseases 16, 17. 

Enamel Tissue Remineralization

Moringa oleifera extract contains the highest values of calcium and phosphate that are required for the remineralization process. Therefore, Moringa oleifera extract is investigated by Younis et al for its ability to treat induced enamel lesion.18 Scanning electron microscopy revealed that Leaves extract of Moringa oleifera loaded-varnish groups IV & V showed the most re-establishment of normal enamel architecture. Elemental analysis of the treated surfaces of Groups IV and V showed the surfaces treated by Moringa oleifera leaf extract loaded-varnish groups had significantly higher Ca, P, and O deposition than the fluoride varnish group. Leaves extract of Moringa oleifera might be considered as a biomimetic material which having capacity to guiding enamel tissue remineralization.19

Study by Risnayanti Anas et al, concluded that there is an increase in the amount of calcium in the teeth after the application of Moringa oleifera based paste and Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) application. Moringa oleifera based paste and CPP-APP are effective to increasing calcium levels in teeth compared to the pre-test group.20

Dental caries is closely related with cariogenic biofilm, an oral biofilm containing a high proportion of Streptococcus mutans 1. Generally, oral biofilm is structurally and functionally organized and contains a balance of normal flora and pathogenic bacteria like S. mutans 22. Su-Kyung Jwa has studied the antimicrobial effects of the M. oleifera leaf extracts on S. mutans and formation of cariogenic biofilm. Extract from M. oleifera leaves was derived using distilled water (DW) and ethyl alcohol (EtOH). S. mutans susceptibility assays were performed for each extract. Cariogenic biofilm was formed with or without DW and EtOH extract, and cariogenic biofilm was treated with both extracts. Both extracts showed antimicrobial activity against S. mutans and inhibited formation of cariogenic biofilm. 23

As Antimicrobial Agent

The leaf extracts of M. oleifera showed varying antimicrobial activity on wide range of microorganisms. 

In a study by Singh et al. (2012), the antimicrobial activity of Moringa oleifera was examined using the main model Kirby-bauer disc diffusion method in which 50% of Moringa oleifera leaf extract was used. The results showed that 50% ethanolic extract successfully displayed anti-bacterial activity however only little. Even at higher concentration, the extract displayed mild inhibitory activity and no activity at all against pseudomonas. 24

Hanaa Elgamily et al carried out a study to assess the antibacterial and antifungal potentials of different parts of Moringa oleifera plant using different extraction methods in attempts to formulate natural dental remedies from this plant. The different extracts of different parts of Moringa oleifera showed an antibacterial effect against Staphylococcus aureus and Streptococcus mutans growth. The novel toothpaste of ethanolic leaves extract has antimicrobial and antifungal potential effects all selected strains.19

Another study indicated that E.coli was found to be equally sensitive to ethyl acetate, acetone and chloroform extracts and had the maximum antibacterial activity among the extracts. S.aureus was sensitive to all the extracts studied. The ethyl acetate had maximum antibacterial activity against S. aureus in comparison to the other extracts. The study revealed that S. gallinarum was also sensitive to all the extracts showing maximum antibacterial activity with ethyl acetate extracts and moderate and equal sensitivity to methanol and chloroform extracts. The ethyl acetate, acetone and methanol extracts showed maximum and equal antibacterial activity against P.aeruginosa. The disc diffusion study revealed that both the Gram positive and Gram-negative organisms showed variablesensitivity to different extracts of M. oleifera. In general, ethyl acetate and acetone extracts showed maximum antibacterial activity against E. coli, S. aureus, S. gallinarum and P. aeruginosa. The antibacterial potential of different extracts of M. oleifera specially of those of ethyl acetate and acetone extracts, demand further in vitro and in vivo studies to exploit their antibacterial action in the treatment of bacterial diseases of man and animals25.

As anti-diabetic agents

Ajit et al., 2003 reported that hypoglycemic activity of Moringa oleifera, with significant blood glucose lowering activities has been confirmed.26 From work of Francis et al., 2004 et al, Methanolic extract of its dried fruits powder has produced N-Benzyl thiocarbamates, N-benzyl carbamates, benzyl nitriles and a benzyl; which prove to trigger insulin release significantly from the rodent pancreatic beta cells and have cyclooxygenase enzyme and lipid peroxidation inhibitory activities .27

As anti-inflammatory agents

Now a days, herbal medicine is being widely used as alternative medicine in developed countries. Leaves of Moringa plant have been shown to have   anti-inflammatory   activities.    Moringa leaves contains flavonoids and tannins   that are    thought   to   have    anti-inflammatory   effects.28

Tannins are polyphenolic compounds that are abundant in Moringa leaves.  The amount of tannin in M.  oleifera ranged between 13.2 gTAE/kg and 20.6 gTAE/kg   in   dry    leaves.   Tannins   have    anti-inflammatory   activity   and    antioxidant   activity.   In    the   inflammatory   process, tannins   can    inhibit   the   production    of   oxidants by neutrophils, monocytes, and macrophages and directly inhibit reactive oxidants such  as   OH  and  NO.29-31

Utilization  of   the  efficacy  of   moringa  leaves developed  in   various  dosage  forms   has  also  begun   to  be  widely   studied.  The  results showed that moringa leaves extract could  be   applied  topically  in   the  form  of   gels, ointments, and creams. The advantage of     giving      topical     anti-inflammatory     drug   preparations  is  that   it  is  easy   to  use  because   it  can  be   directly  applied  to  the  inflamed   area  and  has   fast  absorption,  therefore,     it    can    directly     provide    a    therapeutic   effect.  Previous research has  conducted   an  anti-inflammatory  test   of  5%  moringa   extract  in  gel   preparations  and found that inflammation was reduced by   47.09%.32   Similar   research    was   also   carried    out   using   preparations   in    the   form  of   cream  of  Moringa   leaves  extract  with    a   concentration   of    12%,   and   the    results showed that the cream of Moringa leaves   extract    had   a   fairly    good   anti-inflammatory effect.33

Hepatoprotective Activity34

Alaaeldin     A.    Hamza    et     al investigated    that    the administration of M.O seed extract decreased the CCl4-induced elevation of serum aminotransferase activities and    globulin    level35.    The     elevations    of    hepatic hydroxyproline content and myeloperoxidase activity were also reduced by M.O treatment. Liver fibrosis was induced   by   the    oral   administration   of    20%   carbon tetrachloride (CCl4), twice weekly and for 8 weeks36.   The biochemical and histological results showed that M.O. reduced liver damage as well as symptoms of liver fibrosis.   S.  Fakurazi  et   al  showed  that   initiation  of acetaminophen  toxicities   is  believed  to   be  promoted  by oxidative   stress  during  the   event  of  overdosage.   MO showed    that    the hepatoprotective    activity     gives significant histopathological analysis and reduction of level of   alanine   aminotransferase (ALT), aspartate aminotransferase (AST), and   alkaline   phosphatase (ASP)  in   the  group  treat   with  MO  compared   to  those treated    with     acetaminophen    alone.    The     level    of glutathione (GSH)  was   found  to  be   restored  in  MO treated animal37,38
