The leaves's aroma is distinct and hard to describe, somewhat nutty, reminiscent to fresh hay and definitely pleasant. A similar scent is found in some aromatic rice varieties grown in South East Asia (e.g., Thai jasmine rice). The scent of pandanus leaves develops only on withering; the fresh, intact plants hardly has any odour.

The flavour component of pandanus leaves is not well known. It is speculated that the flavour is due to a volatile product of oxidative degradation of a yellow carotenoid pigment that forms only when the plant whithers. In that respect, there are similarities to saffron and rose, which also contain caroteniod-dervied aroma compounds.
The best candidate is 2-acetyl-1-pyrroline, which was found in pandanus leaves at levels of about 1 ppm (Cereal Chemistry, 70, 381, 1993) and which also occurs in aromatic rice cultivars; another possibility is ethyl formiate, which is also common to rice and pandanus leaves (Naturwissenschaften, 71, 215, 1984).
Yet another study found 3-methyl-2-(5H)-furanone as main volatile compound in pandanus leaves, besides 3-hexanol, 4-methylpentanol, 3-hexanone and 2-hexanone (Flavor and Chemistry of Ethnic Foods, [Proceedings of a Meeting held during the 5th Chemical Congress of North America], Cancun, Nov. 11-15, 1997 (1999)).
The leaves also contain piperidine-type alkaloids (pandamarine, pandamerilactones) with pyrroline-derived structures (Phytochemistry, 34, 1159, 1993)
Pandanus utilissimus, a species native to Madagascar, with unripe fruit.
On distillation, the leaves do yiels traces of an essential oil, but it is unclear to which extent the volatile oil contributes to pandanus' flavour. In Sri Lankan pandanus leaves (Pandanus latifolius, allegedly synonym to P. amaryllifolius), the following aroma components have been identified in concentrations less than one microgramm per kilogramm (ppb) fresh material: styrene 0.62, ?formylthiphene 0.76, linalool 0.29, β-caryophyllene 0.55, β-farnesene 0.18, 1,2-dimethoxybenzene 0.15 and β-selinene 1.24 ppb.

Typically, okra is used as a thickening agent in soups like gumbo because of its ooey-gooey texture, but it can double as a nutritional powerhouse filled with vitamins, minerals, and other nutrients that provide an array of health benefits from treating diabetes to preventing kidney disease. A single cup of raw okra has a little over 30 calories, about 3 grams of dietary fiber, 2 grams of protein, 7.6 grams carbohydrates, 0.1 grams of fat, 21 milligrams of vitamin C, around 88 micrograms of folate, and 57 milligrams of magnesium. This makes okra a nutrition hero and a very available food when it comes to our health.
Cultivation Babbler's Bill, Thunbergia laurifolia is a popular ornamental plant in tropical gardens. It is a long-blooming vine in cultivation. Propagation is from stem cuttings or shoots from the tuberous roots. It is a fast-growing perennial herbaceous climber. It has become an exotic weed in many tropical countries. Teas and medicinal In Malaysia, juice from crushed leaves of T. laurifolia are taken for menorrhagia, placed into the ear for deafness, and applied for poulticing cuts and boils. In Thailand, leaves are used as an antipyretic, as well as for detoxifying poisons. Several Thai herbal companies have started producing and exporting rang jeud tea. Chemistry Iridoid glucosides have been isolated from T. laurifolia. Microwave-dried leaves displayed stronger antioxidant properties than fresh leaves. The antioxidant properties of the infusion from microwave-dried leaves is higher than the commercial rang jeud tea from Thailand.
