The seed kernel contains the glycoside amygdalin, tannin, mucilage (about 22%), ash (1.3%) and fatty oil (14—19%).
In Greece, a tea prepared by boiling dry seeds in water is given in cystitis. The major water-soluble polysaccharide in the mucilage of seeds contains a high proportion of glucuronic acid residues.
The fruit contains pectin (yield 0.53% fresh weight) and is similar to that of apple. lonone glycosides, along with octadienoic acid and its diol, have been isolated from the fruit.
Fruit juice contains thiamine, riboflavin, nicotinic acid, vitamin B6, inositol, pantothenic acid, folic acid and biotin.
The essential oil also gave a number of ionone-related compounds. The buds contain a cyanogenetic glycoside. The bark and shoots yield hydrocyanic acid on distifiation.
Cymbopogon citratus
(DC.)
Stapf.
Synonym Andropogon citratus DC. Family Poaceae.
Habitat Grown in Punjab, Maharashtra, Gujarat and Karnataka.
English Lemongrass.
Ayurvedic Bhuutika, Bhuutikaa.
Action Leaf—stimulant, sudorific, antiperiodic, anticatarrhal. Essential oil—carminative, anticholerin,

depressant, analgesic, antipyretic,
antibacterial, antifungal.
The lemongrass contains a volatile oil, with citral (about 70%), citronellal, geraniol and myrcene as its main constituents. Cetral and citronellal exhibit marked sedative activity.
The lemongrass is taken as a tea for digestive problems; it relaxes muscles of the stomach and gut, relieves spasm and flatulence. In catarrhal conditions, it is taken as a febrifuge.
An infusion of fresh leaves on oral administration has been found to produce dose-dependent analgesia in rats. This analgesic acitivity is caused by myrcene present in the leaf.
Geraniol and d-limonene from the essential oil induce activity of glutathione S-transferase, a detoxifying enzyme, which is believed to be a major factor for chemical carcinogen detoxification.
