A Comprehensive Review on Phytochemical and Pharmacological Properties of Wood Apple (Feronia Limonia)

Abstract

Wood Apple (Feronia limonia L.), a member of a Rutaceae family, is an underutilized yet nutritionally and medicinally important fruit widely found in India and other tropical regions. Traditionally regarded as a “poor man’s fruit”, it has gained attention due to its rich phytochemical composition and diverse therapeutic properties. The fruit grows in semi-arid and dry climates, demonstrating high adaptability and draught tolerance. Despite its abundance, its commercial cultivation and utilization remain limited. Pharmacological studies have reveled multiple biological activities of wood apple, including antidiabetic, antimicrobial, anticancer, antioxidant, hepatoprotective, antiulcer, and anti-inflammatory effects. Experimental studies demonstrate its ability to reduce blood glucose level, improve lipid profiles, and enhance antioxidant enzyme activity. Additionally, extracts of wood apple have shown inhibitory effects against several pathogenic microorganism, supporting its antimicrobial potential.

Introduction

Wood apple (Feronia limonia L.) is an underutilized fruit crop in India belonging to the Rutaceae family. Commonly known as elephant apple, monkey fruit, stone apple, curd apple, and golden apple, it is valued for its nutritional, medicinal, and economic potential. Once considered a "poor man's food," it is now recognized for its health benefits and suitability for processing into products such as jams, jellies, chutneys, beverages, and powders.

1. Introduction and Botanical Characteristics

• Wood apple is a hardy tropical fruit tree that thrives in semi-arid and dry regions.
• It grows well at temperatures of 20–35°C and annual rainfall of 25–60 cm.
• The tree is deciduous, with pinnate leaves and round fruits having a hard woody shell.
• Fruits are acidic when unripe and sweet-tart when ripe.
• Commercial cultivation is usually done through grafting and budding because seed-grown plants take 8–10 years to bear fruit.

2. History

• The species was first described by Carl Linnaeus in 1753 as Schinus limonia.
• Later, the accepted scientific name became Feronia limonia, derived from Feronia, the Roman goddess of forests.
• The fruit has been known and cultivated across South Asia for centuries.

3. Origin and Distribution

• Native to South India and Sri Lanka.
• Widely distributed in:
  • India
  • Bangladesh
  • Pakistan
  • Sri Lanka
  • Southeast Asia
  • Malaysia
  • Indonesia
  • West Africa

In India, it is commonly found in:

• Uttar Pradesh
• Chhattisgarh
• Jharkhand
• Bundelkhand region
• Western Ghats
• Himalayan foothills

The tree is drought-resistant and often grows on roadsides, field boundaries, forests, and homestead gardens.

4. Nutritional and Physicochemical Properties

Wood apple pulp is rich in:

• Beta-carotene (Vitamin A precursor)
• Phenolic compounds
• Dietary fiber
• Antioxidants
• Natural sugars
• Proteins

Typical composition includes:

• Total soluble solids: 10.67–14.33 °Brix
• Acidity: 1.04–4.50%
• Total sugar: 4.08–4.47%
• Protein: 6.3 g
• Vitamin C: 2.6 mg/100 g
• Total phenols: 235 mg/100 g

The fruit is highly perishable and seasonal, making preservation and processing important for year-round consumption.

5. Medicinal Uses

Wood apple has long been used in Ayurveda and traditional medicine.

Traditional Treatments

It is used to manage:

• Diarrhea
• Dysentery
• Indigestion
• Liver disorders
• Respiratory problems
• Piles

Various parts of the tree (fruit, bark, roots, and leaves) are used medicinally.

6. Phytochemical and Antioxidant Properties

Wood apple contains numerous bioactive compounds such as:

• Alkaloids
• Flavonoids
• Phenolics
• Saponins
• Carotenoids
• Ascorbic acid
• Riboflavin

These compounds contribute to:

• Antioxidant activity
• Disease prevention

• Marmin
• Marmelosin (Imperatorin)

These exhibit:

• Anticancer
• Antibacterial
• Anti-inflammatory properties

7. Pharmacological Properties

Anticancer Activity

• Fruit and leaf extracts show cytotoxic effects against breast cancer cell lines.
• Flavonoids and other compounds may inhibit tumor growth and DNA fragmentation in cancer cells.

Antidiabetic Activity

• Ethanolic and methanolic extracts reduce blood glucose levels in diabetic animal models.
• Fruit juice consumption has been linked to reduced fasting and post-meal blood sugar levels.

Antihyperlipidemic Activity

• Improves HDL (good cholesterol).
• Reduces lipid profiles and supports glucose metabolism.
• Helps manage cholesterol and cardiovascular risks.

Antioxidant Activity

Wood apple demonstrates strong antioxidant properties through:

• DPPH radical scavenging
• Ferric reducing power
• Nitric oxide scavenging
• Enhancement of antioxidant enzymes such as:
  • Catalase (CAT)
  • Superoxide dismutase (SOD)
  • Glutathione

Hepatoprotective Activity

• Protects the liver against chemical-induced damage.
• Improves liver enzyme profiles and antioxidant defenses.

Diuretic Activity

• Leaf extracts increase urine production and electrolyte excretion.
• Useful for managing fluid retention.

8. Economic and Industrial Potential

Wood apple has significant potential for:

• Juice and beverage production
• Functional foods
• Nutraceuticals
• Pharmaceutical products
• Value-added processed foods

Products include:

• Jam
• Jelly
• Chutney
• Sherbet (sarbat)
• Ice cream
• Dehydrated powder

Its drought tolerance and adaptability make it suitable for cultivation in marginal lands.
