General info
Pandanus is a genus of monocots of about 600 known species, varying in size from small shrubs less than a meter to medium-sized trees of about 20 meters.

In the Philippines there are 48 species of Pandanus, many of them are endemic, growing in various habitats, from sandy beaches, mangroves and primary forests.
The fruit of some species are edible, eaten by bats, rats, crabs, elephants and lizards. The majority of species are dispersed primarily by water.

Pandan is an erect, branched small tree, growing 3 to 5 meters high; the trunk bearing many prop roots. Leaves are spirally crowded toward the ends of the branches, glaucous, linear lanceolate, slenderly long-acuminate, up to 1.5 meters long, 3 to 5 centimeters wide, the margins and midrib beneath towards the apex, armed with sharp spiny teeth that point toward the apex of the leaf. Male inflorescence is fragrant, pendulous, up to 0.5 meter long. Fruit is solitary, pendulous, ellipsoid to globose-ellipsoid, about 20 centimeters long, each composed of 50 to 75 or more, obovoid, angular, fibrous and fleshy drupes, 4 to 6 centimeters long, narrow below and truncate at the apex; the stone 4- to 10-celled, slightly sulcate between the cells of the apex, becoming yellow-red to bright red-orange at maturity.

- In thickets along seashores throughout the Philippines.
- Also occurs in Indo-Malayan and Polynesian regions, extending to southern China and tropical Australia.

• Anti-Inflammatory: Fresh juice of the aerial root of Pandanus tectorius produced i34.5 % inhibition of carrageenin-induced edema.
• Intestinal Motility / Uterine Stimulant:
Study in rats suggest stimulant property on gastrointestinal motility and uterine stimulant action.
• Antibacterial: Study results indicate that Pandanus tectorium have antibacterial effects on B subtilis but not on E coli, P aeruginosa, C albicans or S aureus. (3)

• Antitubercular / Triterpenes and Phytosterols:
Study of a chloroform extract of leaves yielded a new tirucallane-type triterpene, 24,24-dimethyl-5β-tirucall-9(11),25-dien-3-one (1), squalene and a mixture of the phytosterols stigmasterol and β-sitosterol. Compound 1 inhibited the growth of Mycobacterium tuberculosis H37Rv with a MIC of 64 μg/mL, while squalene and the sterol mixture have MICs of 100 and 128 μg/mL, respectively. (7)
• Fruits /Phenolic Compounds and Flavonoids:
Study isolated 15 compounds (ten phenolics and five flavonoids) from the fruits of P. tectorius. Of the compounds, trans-ethyl acetate was the highest one with about 0.1% of the dry material. Most of the compounds possessed anti-oxidative activities, with some anti-inflammatory activities. (10)
• Diuretic / Leaves:
A previous study has shown diuretic activity in a leaf extract. This study isolated squalene (1) from a chloroform extract. Both squalene 1 and the chloroform extract exhibited positive diuretic effects, although no comparable to the positive control, furosemide. (13)
• Neurobehavioral Activity / Leaves:
Study evaluated an ethyl acetate fraction and n-butanol fraction of hydroalcoholic leaf extract for neurobehavioral activity using elevated plus maze, open field test and forced swim test in mice models. Results showed antidepressant and anxiolytic action. Phytochemical screening yielded flavonoids which could be responsible for the pharmacological action. Acute toxicity study on mice per OECD guidelines showed no significant toxicity. (14)
• Anti-Hyperlipidemic / Caffeoylquinic Acids:
Study evaluated the anti-hyperlipidemic effect and mechanism of action of P. tectorius fruit extract in hamsters fed a high fat-diet. Treatment with PTF-b (fruit ethanol extract) enriched in caffeoylquinic acids (CQAs) significantly stimulated the activation of AMP-activated protein kinase (AMPK) as well as serum and hepatic lipoprotein lipase, with moderation of hyperlipidemia and improvement of liver lipid profile. (16) Study yielded ten caffeoylquinic acids (CQAs) from the anti-hyperlipidemic extract of fruits of P. tectorius. Three CQAs tested in HepG2 cells significantly reduced the intracellular content of total cholesterol and total triglycerides. (22)
• Antioxidant / Antibacterial / Cytotoxicity Study / Fruits:
Study evaluated the antibacterial and antioxidant activities, total phenolic content and cytotoxicity properties of P. tectorius fruit extracts against normal and cancer cell lines (HeLa, HepG2 and MCF-7). An ethyl acetate extract from fruit core parts showed highest antioxidant capacity (IC50=0.8 ± 0.20 mg/mL), while an ethyl acetate extract from key parts showed highest antibacterial activity with inhibition zone of 10-15 mm, but less than commercial antibiotics. On cytotoxicity study, all extracts did not show activity against all selected cell lines (IC50>30 µg/mL. (see constituents above) (18)
α-Glucosidase Inhibitory Activity / Fruits:
Study of fruits yielded one new dihydrofurocoumarin, named pandanusin A, along with 15 known compounds (2-16). The isolated compounds (1-12, 14) showed better α-glucosidase inhibitory activity (IC50 range of 14.4-81.5 µM) than standard drug acarbose (IC50=215.5 µM). (see constituents above) (19)
• Antitubercular Triterpenes and Phytosterols / Leaves:
Bioassay-guided chromatographic purification of the antitubercular chloroform extract of P. tectorius var. laevis leaves yielded a new tirucallane-type triterpene, 24,24-dimethyl-5β-tirucall-9(11),25-dien- 3-one (1), squalene and a mixture of the phytosterols stigmasterol and β-sitosterol. The new triterpene inhibited the growth of Mycobacterium tuberculosis H37Rv with MIC of 64 µg/mL, while squaline and the sterol mixture have MICs of 100 and 128 µg/mL, respectively. (21)
• Cytotoxic Steroids / KB (Human Epidermal Carcinoma) Cell Line / Stem Bark:
Study of n-hexane extract of stem barks showed good cytotoxicity activity against KB (a human epidermal carcinoma) cell line with IC50 of 45.33 µg/mL. Study of the extracts isolated four compounds viz. stigmast-4-en-3-one (1), stimasta-4,22-dien-3-one (2), cycloucalenol (3), and stigmast-22-en-3ß-ol (4). Compound 2 showed moderate cytotoxic activity against KB cell line with IC50 of 88.96 µg/mL. (23)
• Anti-Inflammatory / Antinociceptive / Leaves:
Study evaluated the anti-inflammatory and antinociceptive activity of ethanolic extract of fresh leaves of P. tectorius using carrageenan-induced paw edema in rats and tail-flick method in mice. Results showed anti-inflammatory activity equivalent to phenylbutazone; activity was attributed to inhibition of prostaglandins and leukotrines release. Antinociceptive activity was comparable to ibuprofen. Phytochemical screening yielded tannins, steroids, triterpenes, and flavonoids. (24)
• Increase Insulin Sensitivity / Regulation of Hepatic Glucose and Lipid Metabolism / Caffeoylquinic Acid / Fruit: Study evaluated the antihyperglycemic and antihyperlipidemic effects of CQA-rich P. tectorius fruit extract in diabetic mice. Treatment with the fruit extract significantly decreased body weight and fasting glucose levels, alleviated hyperinsulinism and hyperlipidemia, and decreased glucose levels in OGTT. Results suggest CQA-rich fruit extract may alleviate hyperglycemia and dyslipidemia via activation of AMPK-AS160-GLUT 4 pathway in skeletal muscle and inhibition of gluconeogenesis and lipogenesis in the liver.
