Folk Mainphal.

Action Fruit—nervine, calmative,

antispasmodic, emetic,

anthelmintic, abortifacient. Used as

a substitute for ipecacuanha.

The Ayurvedic Pharmacopoeia of India

recommends the dried fruit in

chlorosis, common cold, rhinitis and

obstinate skin diseases.

The activity of the drug is attributed

to the presence of saponins which occur

to the extent of –% in fresh fruits

and about % in dried whole fruit.

The saponins are concentrated mostly

in the pulp. Amixture of two saponins,

viz. randialic or neutral saponin and

randialic acid or acid saponin has been

isolated from the pulp. On complete

hydrolysis both the saponins yield oleanolic

acid as sapogenin. Ursosaponin,

isolated from the ethanolic extract of

the dried whole fruit, gave ursolic acid

and glucose. Randianin, isolated from

the fruit, gave a haemolytic triterpenoid

saponin.

R

536 Randia uliginosa DC.

In experimental animals, the drug

caused haemolysis both in vitro and in

vivo. Crude saponin fraction showed

haemolytic, molluscidal and immunostimulating

activities.

The enzymes present in the radish

are phosphatase, catalase, sucrase,

amylase, alcohol dehydrogenase and

pyruvic carboxylase.

Radish contains caffeic acid and ferulic

acid which exhibit hepatoprotective

and choleretic properties. It contains

choline which prevents deposition

of fat in liver. Amino acids, ornithine,

citrulline, arginine, glutamic

acid and asparatic acid remove toxins

from the body and urea acumulation.

Radish is a good source of ascorbic

acid (– mg/ g), trace elements

include aluminium, barium, lithium,

manganese, silicon, titanium, also iodine

(upto  mcg/ g) and ascorbigen.

Roots, leaves, flowers and pods are

sinus tachycardia, anxiety, tension

and psychomotor irritation,

when dietetic measures alone

are not sufficient. (German

Commission E.)

(Average daily dose:  mg drug

corresponding to  mg total alkaloid.)

Treatment is usually administered with

a diuretic to prevent fluid retention

which may develop if Rauvolfia root is

given alone. (WHO.) Contraindicated

in depression, bleeding disorders, gastric

and duodenal ulcers. (Sharon M.

Herr.) Also contraindicated in pregnancy,

since it has both teratogenic

and abortifacient potential. (Francis

Brinker.)

The root and root bark are rich in

alkaloids, the most important being

reserpine, others, around , which include

ajmaline, ajmalicine (raubasine),

ajmalicine, yohimbine, coryanthine,

iso-ajmaline, neo-ajmaline, papaverine,

raubasine, rauwolscine, rescinnamine,

reserpine, sarpagine, serpentine,

serpentinine, serpinine and deserpidine.

Reserpine is hypotensive and tranquilizer,

used for certain forms ofmental

disorders. Ajmalicine (raubasine)

and rescinnamine are also hypotensive

and tranquilizer. Deserpidine is

sedative, as well as hypotensive. Ajmaline

exhibits antiarrhythmic activity.

A

number of Rauvolfia species are

found in India: R. beddomei Hook. f.;

R. densiflora Benth ex Hook. f. (Himalayas,

Khasi and Aka Hills; Western

and Eastern Ghats); R. micrantha

Hook. f; known as Malabar Rauvolfia,

(Kerala, up to an altitude of  m)

The roots of R. beddomei contain

ajmalicine, sarpagine and serpentine,

but no reserpine. R. densiflora yielded

.% of total alkaloids (reserpine

.%). R. micrantha gave ajmalicine,

raunamine, reserpiline, sarpagine,

neosarpagine, in addition to reserpine.

(In classical Ayurvedic texts, Nakuli

and Gandha-naakuli were included in

compound formulations for mental

diseases.)

also inhibits in vitro growth of different

strains of Mycobacterium tuberculosis.

Clinical trials have shown that

pristimerin is effective in the treatment

of inflammatory conditions of

the naso-pharyngeal mucosa resulting

from common cold and influenzal infections.

It is found useful as an adjunct

to the common antibiotic therapy of

respiratory inflammations of both bacterial

and viral origin, and is reported

to possess antitumour properties, but

its high toxicity precludes its use as

a cancero-static agent.

(Natural Medicines Comprehensive

Database, .)

There are three main types of rhubarbs—

Chinese, Indian or Himalayan,

and Rhapontic.

The Chinese rhubarb consists of the

rhizomes and roots of Rheum palmatum

and R. officinale.

TheIndian rhubarb consists of dried

rhizomes of R. emodi and R. webbianum;

rhizomes and roots of R.

moorcroftianum and R. spiciforme are

also reported to be mixed with the

drug. R. rhaponticum is the Rhapontic

rhubarb.

Rheum moorcroftianum Royle (the

Himalayas at altitudes of ,–

, m., chiefly in Garhwal and Kumaon)

possesses properties similar to

those of R. emodi and the roots are

mixed with the latter.

Rheum spiciforme Royle (drier

ranges of Kumaon and Sikkim at altitudes

of ,–, m.) also possesses

purgative properties. The rhizomes

and roots aremixed upwithHimalayan

rhubarb.

Rheum webbianum Royle (the western

and central Himalayas at altitudes

of ,–, m.) is the source of

Himalayan rhubarb.

Rheum palmatum is esteemed as

the best type of (Chinese) rhubarb.

Two new stilbene glycosides, -Omethylpiceid

and rhapontin, isolated

from the roots, exhibited moderate

alpha-glucosidase inhibitory activity.

Anthraquinone glucoside, pulmatin,

isolated from the roots, along

with its congeners, chrysophanein and

physcionin, showed cytotoxic activity

against several types of carcinoma

cells. Polysaccharides, isolated from

the roots and rhizomes, contained lyxose,

Key application In constipation.

Contraindicated in acute intestinal

inflammation and obstruction.

(German Commission E, ESCOP,

The British Herbal Pharmacopoeia,

WHO.)

Rhubarb contains ,-dihydroxyanthracene

derivatives. The laxative

effect of the herb is primarily due to its

influence on the motility of the colon,

inhibiting stationary and stimulating

propulsive contractions. Stimulation

of the chloride secretion increases the

water and electrolyte content of stool.

(German Commission E.)

The plant extract of R. officinale

is found to be strong and effective

scavenger of oxygen radicals in xanthine/

xanthine oxidase and other systems
