Xanthophyll esters, carotenes, and tocopherols has been identified and quantified in the fruit of seven mexican mango cultivars by liquid chromatography-atmospheric pressure chemical ionization-time-of-flight mass spectrometry. 5-Alkyl- and 5-alkenylresorcinols, as well as their hydroxylated derivatives, extracted from mango (MI) peels, purified on polyamide and characterized by high-performance liquid chromatography/atmospheric pressure chemical ionization mass spectrometry (HPLC/APcI-MS) for the first time. HPLC method was developed to determine carotenoids in Taiwanese mango. A rapid method was developed for quantitative determination of beta-carotene, including cis-isomers, in dried mango. Polyphenols have been characterized in mango puree concentrate by HPLC with diode array and mass spectrometric detection.
Quantitative analysis of the compounds has been performed by HPLC, and mangiferin was found to be the predominant component. All structures were elucidated by ES-MS and NMR spectroscopic methods.
MANGO WOOD FREE
Phenolic Antioxidants, Free Sugars and Polyols isolated and analyzed from Mango (MI) Stem Bark. An unusual fatty acid, cis-9, cis-15-octadecadienoic acid was isolated from the pulp lipids of mango. The fruit pulp contains vitamins A and C, β-carotene and xanthophylls. The leaf and flower yield an essential oil containing humulene, elemene, ocimene, linalool, nerol and many others. Root of mango contains the chromones, 3-hydroxy-2-(4’-methylbenzoyl)-chromone and 3-methoxy-2-(4’-methyl benzoyl)-chromone. The flower yielded alkyl gallates such as gallic acid, ethyl gallate, methyl gallate, n-propyl gallate, n-pentyl gallate, n-octyl gallate, 4-phenyl gallate, 6-phenyl-n-hexyl gallate and dihydrogallic acid. Mangostin, 29-hydroxy mangiferonic acid and mangiferin have been isolated from the stem bark together with common flavonoids. Indicoside A and B, manghopanal, mangoleanone, friedelin, cycloartan-3β-30-diol and derivatives, mangsterol, manglupenone, mangocoumarin, n-tetacosane, n-heneicosane, n-triacontane and mangiferolic acid methyl ester and others isolated from stem bark of MI. Most parts of the tree are used medicinally and the bark also contains tannins, which are used for the purpose of dyeing. The kernels are converted into flour after soaking in water and eliminating the astringent principles.
MANGO WOOD CRACKED
The gum is used in dressings for cracked feet and for scabies. The bark is astringent, it is used in diphtheria and rheumatism, and it is believed to possess a tonic action on mucus membrane. Fumes from the burning leaves are inhaled for relief from hiccups and affections of the throat. The seeds are used in asthma and as an astringent.
The juice is restorative tonic and used in heat stroke. Ripe mango fruit is considered to be invigorating and freshening. All parts are used to treat abscesses, broken horn, rabid dog or jackal bite, tumour, snakebite, stings, datura poisoning, heat stroke, miscarriage, anthrax, blisters, wounds in the mouth, tympanitis, colic, diarrhea, glossitis, indigestion, bacillosis, bloody dysentery, liver disorders, excessive urination, tetanus and asthma. Various parts of plant are used as a dentrifrice, antiseptic, astringent, diaphoretic, stomachic, vermifuge, tonic, laxative and diuretic and to treat diarrhea, dysentery, anaemia, asthma, bronchitis, cough, hypertension, insomnia, rheumatism, toothache, leucorrhoea, haemorrhage and piles. Mangiferin, being a polyphenolic antioxidant and a glucosyl xanthone, it has strong antioxidant, anti lipid peroxidation, immunomodulation, cardiotonic, hypotensive, wound healing, antidegenerative and antidiabetic activities. Mango is one of the most popular of all tropical fruits. According to ayurveda, varied medicinal properties are attributed to different parts of mango tree.
Mangoes belong to genus Mangifera which consists of about 30 species of tropical fruiting trees in the flowering plant family Anacardiaceae. Mangifera indica (MI), also known as mango, aam, it has been an important herb in the Ayurvedic and indigenous medical systems for over 4000 years.
