Diastase Health Dictionary

A protein that acts as a catalyst for the body’s metabolic processes. The body contains thousands of enzymes, with each cell producing several varieties. The ?rst enzyme was obtained in a reasonably pure state in 1926. Since then, several hundred enzymes have been obtained in pure crystalline form. They are present in the digestive ?uids and in many of the tissues, and are capable of producing in small amounts the transformation on a large scale of various compounds. Examples of enzymes are found in the PTYALIN of saliva and DIASTASE of pancreatic juice which split up starch into sugar; the PEPSIN of the gastric juice and the trypsin of pancreatic juice which break proteins into simpler molecules and eventually into the constituent amino acids; and the thrombin of the blood which causes coagulation.

The diagnosis of certain disorders can be helped by measuring the concentrations of various enzymes in the blood. After a heart attack (myocardial infarction – see HEART, DISEASES OF), raised levels of heart enzymes occur as a result of damage to the cells of the heart muscle. Some inherited diseases such as GALACTOSAEMIA and PHENYLKETONURIA are the result of de?ciencies of certain enzymes.

Enzymes can be a useful part of treatment for some disorders. STREPTOKINASE, for example, is used to treat THROMBOSIS; wound-dressings containing papain from the pawpaw fruit – this contains protein-digesting enzymes – assist in the healing process; and pancreatic enzymes can be of value to patients with malabsorption caused by disorders of the PANCREAS.... enzyme

Synonym: H. schulli (Ham.) MR & SM Almeida. H. spinosa T. anders. Asteracantha longifolia (L.) Nees.

Family: Acanthaceae.

Habitat: Throughout India along the banks of fresh or stagnant water ditches and swampy grounds, mixed with marshy grasses and sedges.

Ayurvedic: Kokilaaksha, Kokilaak- shi, Ikshuraka, Ikshura, Kshuraka, Bikshu, Kaakekshu.

Unani: Taalmakhaanaa.

Siddha/Tamil: Neermulli.

Action: Leaves, roots and seeds— diuretic; used for diseases of the urinogenital tract, spermatorrhoea. Seeds promote sexual vigour, arrest abortion and cure diseases due to vitiated blood. Also used for arthritis and oedema.

The seeds contain large amounts of tenacious mucilage and potassium salts, which may be responsible for the diuretic property of seeds. The seeds also contain linoleic acid (71%), besides diastase, lipase and protease.

EtOH (50%) extract of the plant is spasmolytic and hypotensive.

The chloroform soluble fraction of ethanolic extract of aerial parts exhibited promising hepatoprotective activity in albino rats.

The plant contains lupeol, stigmas- terol and hydrocarbons.

Dosage: Seed—3-6 g powder; ash—1-3 g. (CCRAS.)... hygrophila auriculata

Linn.

Family: Gramineae; Poaceae.

Habitat: Uttar Pradesh, Bihar and Punjab.

English: Sugarcane, Noble Cane.

Ayurvedic: Ikshu, Dirgha-chhada, Bhuurirasa, Morata, Asipatra, Madhutrna, Gudamuula, Trnarasa.

Unani: Gannaa, Naishakar.

Siddha/Tamil: Karumbu, Nanal.

Action: Cane Juice—restorative, cooling, laxative, demulcent, diuretic, antiseptic. Used in general debility, haemophilic conditions, jaundice and urinary diseases.

The Ayurvedic Pharmacopoeia ofIn- dia recommends the juice of the stem in haemorrhagic diseases and anuria; and the root in dysuria.

Sugarcane juice contains surcose (70-80% of soluble solids in the juice), glucose and fructose. Non-sugar constituents present in the cane juice are carbohydrates other than sugars. As- paragine and glutamine are prominent amino acids in the juice. Other amino acids include alanine, gamma- amino butyric acid, aspartic and glutamic acids, glycine, leucine, lysine, serine and tyrosine. The presence of phenylalanine, histidine, valine, proline, threonine and arginine, pipecolic acid, methionine and tryptophan has also been reported.

Aconitic acid constitutes about three-fourths of the total carboxylic acid present in the juice.

Vitamins present in the juice are: thiamine, riboflavin, niacin, pantothenic acid, biotin, and vitamin D; enzymes include diastase, invertase, lac- tase, peroxidase, tyrosinase.

Phenols in the cane juice are mainly polyphenols from tannin and antho- cyanin from the rind.

Cane juice contains glycolic acid which improves skin complexion as it has antiwrinkle effect, prevents scaly growth and increases natural collagen and elastin in the skin.

Enzymes present in the seeds include large quantities of diastase and invertase.

An ester, vanilloyl-l-O-beta-D-glu- coside, has been isolated from the bagasse.

The leaves contain alpha-amylase and glutathione-S-transferase.

Dosage: Stem—200-400 ml juice; rootstock—15-30 g for decoction. (API, Vol. IV.)... saccharum officinarum

Roxb.

Synonym: Z. montanum (Koen.) Link ex. A. Dietr. Z. purpureum Rosc.

Family: Zingiberaceae.

Habitat: Wild throughout India, also cultivated in tropical parts of India.

English: Cassumunar Ginger.

Ayurvedic: Vanardraka, Peja, Peyu, Aardikaa, Shringaberikaa.

Folk: Adarakhi, Bana-adarakhi.

Action: Rhizome—carminative, stimulant, antispasmodic. Used for diarrhoea and colic.

The occurance of an active diastase in the rhizome has been reported.

The enzyme resembles in its activity with alpha-amylase of Aspergillus oryzae. The rhizome gave an essential oil consisting of terpinen-4-ol (about 35%); other constituents are alpha- and beta-pinene, sabinene, myrcene, terpinene, limonene, p-cymene and terpinolene. The fresh rhizomes contain phenyl butenoic dimers, along with cyclohexane derivatives. Hex- ane extract of the rhizome contained (E)-4-(3'4'-dimethoxyphenyl)-but-3- en-l-ol, known as compound D. Compound D showed antispasmodic effect on guinea-pig ileum and tracheal smooth muscle, also a dose-related uterine relaxant effect in situ in non- pregnant rats; in pregnant rats the response varied with the period of pregnancy. Aqueous extract of the rhizome showed smooth muscle relaxant and anti-inflammatory activity Antioxi- dant activity was found to be more intense than that of known curcum- inoid antioxidants.
