Pandanus Fruit

Pandanus fruit encompasses several species (P. tectorius, P. conoideus, P. odoratissimus) rich in carotenoids, flavonoids, and phenolic compounds that modulate NF-κB signaling, inhibit HMG-CoA reductase, and scavenge free radicals. A 2019 study in Phytomedicine (PMID 30836215) demonstrated that Pandanus tectorius fruit extract modulates gut microbiota composition and exerts significant anti-hyperlipidaemic effects, while research in J Adv Pharm Technol Res (PMID 32154156) confirmed its antihypercholesterolemic and antiatherosclerotic potency via upregulation of scavenger receptor-B1 gene expression.

Origin & History

Pandanus Fruit (Pandanus tectorius), commonly known as 'screwpine,' is native to Southeast Asia, the South Pacific, and coastal regions of the Indian Ocean. Thriving in tropical shorelines and mangrove ecosystems, its vibrant red-orange fruits are a significant source of nutrients, offering sustained energy and antioxidant protection for functional wellness.

Historical & Cultural Context

Pandanus fruit has been revered across Pacific Island and Southeast Asian cultures for centuries as a symbol of nourishment and abundance. It is central to many traditional dishes, providing sustenance and cultural significance, while its holistic benefits bridge ancient traditions with modern wellness.

Health Benefits

- Provides essential nutrients including vitamin C and B-vitamins that support immune function, skin health, and energy metabolism.
- Offers robust antioxidant properties through flavonoids and phenolic compounds that combat oxidative stress and promote cellular resilience.
- Aids digestive health with its high fiber content, promoting bowel regularity and supporting a healthy gut microbiome.
- Boosts energy levels through its carbohydrate-rich profile, providing sustained energy for physical endurance.
- Delivers anti-inflammatory support, traditionally used to ease inflammation and joint discomfort.

How It Works

Pandanus fruit's bioactive phenolic compounds—including naringenin, malvidin, and trans-ethyl caffeate—suppress inflammatory cascades by inhibiting NF-κB nuclear translocation, thereby downregulating COX-2 and iNOS expression and reducing nitric oxide (NO) and prostaglandin E2 (PGE2) production. The fruit's anti-hyperlipidaemic action operates through direct inhibition of HMG-CoA reductase (the rate-limiting enzyme in cholesterol biosynthesis) and upregulation of hepatic scavenger receptor-B1 (SR-B1), which enhances reverse cholesterol transport (PMID 32154156). Carotenoids, particularly β-carotene and α-tocopherol concentrated in Pandanus conoideus oil, neutralize reactive oxygen species (ROS) via electron donation to DPPH and ABTS radicals and enhance endogenous antioxidant enzyme activity including superoxide dismutase (SOD) and glutathione peroxidase (GPx) (PMID 40480135). Additionally, Pandanus tectorius fruit extract modulates gut microbiota composition by enriching beneficial Bacteroidetes populations and suppressing Firmicutes, contributing to improved lipid metabolism and intestinal barrier integrity (PMID 30836215).

Scientific Research

Adkar et al. (2014) in Advances in Pharmacological Sciences (PMID 25949238) comprehensively reviewed the ethnopharmacology of Pandanus odoratissimus, documenting its antioxidant, anti-inflammatory, analgesic, and hepatoprotective properties attributed to phenolic acids, flavonoids, and terpenoids. Wu et al. (2019) in Phytomedicine (PMID 30836215) showed that Pandanus tectorius fruit extract (PTF) significantly reduced serum total cholesterol, triglycerides, and LDL-C in hyperlipidaemic animal models while positively modulating gut microbiota, increasing Bacteroidetes-to-Firmicutes ratios. Andriani et al. (2020) in J Adv Pharm Technol Res (PMID 32154156) demonstrated that P. tectorius fruit extracts exert antihypercholesterolemic and antiatherosclerotic effects by increasing scavenger receptor-B1 (SR-B1) gene expression and inhibiting 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase activity. Englberger et al. (2006) in Public Health Nutrition (PMID 16923295) quantified carotenoid content across multiple pandanus fruit cultivars from the Republic of Kiribati, identifying provitamin A β-carotene concentrations up to 840 μg/100 g in certain cultivars, establishing pandanus as a critical micronutrient source in Pacific Island diets.

Clinical Summary

Current evidence is limited to animal studies with no human clinical trials reported. In carrageenan-induced paw edema rat models, Pandanus tectorius aqueous extract at 500 mg/kg showed paw thickness change of 0.110 ± 0.024 mm at 6 hours and inflammatory grade of 1.80 ± 0.20, performing equivalent to indomethacin (p=1.00). The phenolic-ethyl fraction demonstrated 16.67% paw edema reduction compared to 29.63% for ibuprofen control. While animal data shows promise for anti-inflammatory and antioxidant effects, human clinical evidence is needed to establish therapeutic efficacy and optimal dosing.

Safety & Interactions

Pandanus fruit is generally recognized as safe when consumed as a traditional food, with no acute toxicity reported in ethnopharmacological reviews (PMID 25949238); however, rigorous human clinical safety trials remain limited. Due to its demonstrated HMG-CoA reductase inhibitory activity (PMID 32154156), concurrent use with statin medications (e.g., atorvastatin, simvastatin) may theoretically potentiate cholesterol-lowering effects and increase the risk of adverse events such as myopathy, warranting caution and physician consultation. The high carotenoid content in Pandanus conoideus oil (PMID 40480135) may interact with fat-soluble vitamin supplements (vitamins A, D, E, K) and anticoagulant medications such as warfarin, as tocopherols can affect platelet aggregation and prothrombin time. Individuals with known allergies to Pandanaceae family plants, pregnant or lactating women, and those on CYP3A4-metabolized medications should consult a healthcare provider before supplementation, as specific CYP450 interaction data for pandanus bioactives have not yet been fully characterized.
