Plant Taxonomy Laboratory, Department of Botany, University of Rajshahi, Bangladesh

Abstract: Taxonomy and medicinal uses on the family Amaranthaceae growing throughout the Rajshahi, Bangladesh was carried out during September 2011 to December 2012. A total of 14 species under 8 genera belonging to the family Amaranthaceae were collected and identified. Out of the total number of species Achyranthes aspera L., Aerva lanata (L.) Juss. ex Schult., Alternanthera philoxeroides (Mart.) Griseb., Alternanthera sessilis (L.) R. Br. Ex Roem. & Schult., Amaranthus spinosus L., Amaranthus viridis L., Amaranthus livids L., Amaranthus tricolor L., Amaranthus blitum L., Celosia cristata L., Gomphrena globosa L. were common and Cyathula prostrata (L.) Blume., Digera muricata (L.) Mart., Gomphrena celosioedes Mart. was rare species in the study area. For each species botanical name, local name, habit, habitat, phenology, status of occurrence, chromosome number and medicinal uses have been mentioned.

1. Introduction

A family of about 65 grnera and 900 species, Amaranthaceae are mostly distributed in tropical but also in temperate regions. About 18 genera and over 50 species have been reported from India. Some of the larger genera with the number of their approximately reported species and common names are Alternanthera (200, alligator weed), Gomphrena (100, globe amaranth), Iresine (80, gizzard plant), Amaranthus (60, pigweed), and Celosia (60, Celosia). Ornamental plants of the family known for their multicoloured foliage and beautiful inflorescence are Amaranthus caudatus (Foxtail), A. tricolor, A. salixifolius, Celosia cristata (cocks comb; white, purple or yellowish-red panicles), Deeringia amaranthoides, Gomphrena globosa (globe amaranth), Iresine herbtsii (purplish-red foliage) and I. lindenii (red foliage). Edible plants of the family, of which the leaves and young shoots are used as vegetable are Amaranthus blitum (Amaranth or Chaulai), A. caudatus, A. hybridus, A. spinosus (Katili Chaulai), A. tricolor (Bari Chaulai), A. viridis, Celosia argenta and Digera muricata (Lehsua). Inflorescence paste of Achyranthes aspera (Latjeera or Chirchita) is used as an antidote against snake and scorpion bites [16].

The main objectives of this work will be detailed study on the taxonomic and medicinal aspects of the family Amaranthaceae occurring Rajshahi, Bangladesh.

2. Materials and Methods

The present study in based on the intensive field of the area during the period of September 2011 to December 2012. A total of 14 species under 8 genera belonging to the family Amaranthaceae were collected and identified. The methods employed during the study were designed with the sole purpose of eliciting the precious wealth of information on the medicinal uses of plants practiced by the local people. Detailed survey has made in gathering information regarding use of medicine has been documented. Usually, the survey in each locality started with the interview of elderly and experienced members, locally known as Hakims. Besides, this the common people of the surveyed localities who themselves have used these plant-based for health treatments were interviewed to prove veracity of the curative features of plants. Medicinal uses and data about the treatment of various alignments based on the information gathered by using questionnaires are given subsequently.

The collected specimens were identified studying related taxonomic books and booklets from the library of Rajshahi University. The major collected materials were identified and described up to species with the help of [1,2,4,6,8-15] were consulted. For the current name and up to date nomenclature [1,5,7] were also consulted. All the collected plant specimens were kept in the Herbarium, Department of Botany, and University of Rajshahi, Bangladesh.

3. Results and Discussion

The present research work is based on the local knowledge of most commonly used medicinal plants of Amaranthaceae family. Each Medicinal plant species is provided with its scientific name, local name, chromosome number (Fedorov, 1969), plant parts (Such as leaf, root, stem, fruit, latex, whole plant, seed, inflorescence and bark) mostly used and uses.

The result obtained in the investigation need to be rigorously subjected to pharmachemical analysis in order to validate their authenticity and future prospects. The paper has only documented the herbal health remedies presently in vogue in the region and does not prescribe or recommend for their use till further determination by the pharmacologist. Data have been gathered on the traditional uses of plant species, especially for asthma, abscess, anthelmintic, astringent, bronchitis, bedsores, cancer, cough, diuretic, diarrhea, dysentery, eczema, earache, headache, inflammations, jaundice, kidney disease, leprosy, paralysis, skin diseases, scabies, toothache, ulcers, ringworm and others.

4. Conclusion

Taxonomy and medicinal uses on the family Amaranthaceae growing throughout the Rajshahi, Bangladesh was carried out during September 2011 to December 2012. A total of 14 species under 8 genera belonging to the family Amaranthaceae were collected and identified. The present study may be a preliminary contribution of this area using standard research methods, focusing on medicinal plants and their local uses for the healthcare. This detailed information will be helpful for the pharmacognosist, botanist, ethno-botanist and pharmacologist for the collection and identification of the plant for their research work and isolation of plant products benefitting human health.
