“…Understanding genetic variability is fundamentally important for the development of strategies that aim to conserve the pool of genes that may express morphoagronomic characteristics of interest (Abdul Kareem et al, 2012). Therefore, in this study, the genetic diversity of yacon was verified for the first time in the State of Espírito Santo to understand the relationships between the accessions cultivated in the State.…”

Yacon cultivation has been intensified and the investigations of this crop have increased at the scientific, agricultural, and social levels because the roots of yacon show beneficial properties for human health, such as reducing cholesterol and glucose blood levels. Since the investigations involving yacon are very recent, there is little information available in terms of the genetic characterization of the cultivated genotypes. In view of the lack of information on the accessions cultivated in the State of Espírito Santo, Brazil, this pioneering study aimed to characterize 60 accessions cultivated in the state using ISSR yacon markers with emphasis on identifying the genetic diversity among the materials. The 20 ISSR primers used produced a total of 82 fragments, 39.6% of which presented polymorphism. The number of fragments per primer ranged from 1 to 10. The dissimilarity values ranged from 0 to 0.54 according to the Jaccard coefficient. A dendrogram was generated in which the accessions were divided into 3 groups; group 1 contained 58 individuals and groups 2 and 3 had only one individual in each group. The clustering of 58 accessions in a single group shows the low diversity in the materials examined. This low diversity indicates that new genotypes must be introduced in order to promote increased variability, which would minimize the adverse effects caused by biotic and abiotic factors.

“…Sweet flag commonly found in moderate and submoderate rainfall regions of the world and is indegenous to China, Japan, South East India, Asia, Mongolia, Kazakhstan, and Sulawesi (Khwairakpam et al, 2017). This herb naturally recorded all over India like in swamp areas and also cultivated up to an altitude of 2200 m in the Himalayas especially Karnataka, Assam, Tamil Nadu, Kerala and Andhra Pradesh (Kareem et al, 2012). In India Acorus calamus is cultivated in the swampy areas of Kashmir, Shirmaur, Manipur, Nagahills, Koratagere taluka and Karnataka (Gagan et al, 2015).…”

Medicinal plants have been used in the preparation of medicine since ancient times and may even be considered the origin of modern medicine. Acorus calamus (Linn.) is one such a medicinal herb that found as a member of family Acoraceae and most commonly known as âsweet flagâ. Herb is commonly distributed in the moderate and the sub moderate rainfall regions of the Asia, Europe and North America. It is a tall, semi-aquatic in habitat, monocotyledonous, perennial, aromatic herb with branched cylindrical spreading rhizomes. The well growth habitats for sweet flag include edges of small lakes, rivers, marshes, ponds in temperature ranging from 10 to 38 Â°C. The major phyto constituents of herb include alpha-Asarone, beta Asarone, elemicine, alpha-terpineol and acorone, acorenone, acoragermacrone cis-isoelemicine, isoeugenol and their methyl ethers, camphene, P-cymene, beta-cadinene, camphor, beta-gurjunene, 7-dienol, shyobunones, isohyobunones, calamusenone alpha-selinene, terpinen-4-ol, alpha-calacorene 2-deca-4, linalool and pre-isocalamendiol etc. Acorus calamus (Vacha) constituents important for treatment of the various types of the ailments like epilepsy, diarrhea, dysentery, mental ailments, chronic bronchial catarrh, intermittent and tumors. It also has the insecticidal, antifungal, anticancerous, neuroprotective, antioxidant, antibacterial, antidiabetic, antidiarrhoeal, analgesic and anticonvulsant, spasmolytic, vascular modulator activities. The present review focuses on the detailed composition of Acorus calamus its different phytoconstituents having various pharmacological activities that helps to improve the health and prevent from various kinds of ailments.

“…It is native to China, Japan, South East Asia, Asia, and Sulawesi and is found in moderate and sub moderate rainfall regions around the world [13]. In India, A. calamus is found naturally in swamps and is also cultivated in the Himalayas, particularly in Karnataka, Assam, Tamil Nadu, Kerala, and Andhra Pradesh, up to an altitude of 2200 m [14]. The members are aromatic, perennial, marshy herbs with rhizomes, bearing EO [15].…”

Comparative chemical composition and pesticidal evaluation of Acorus calamus accessions collected from different geographical locations

The objectives of the present study were to investigate the phytochemical composition of essential oils (EO) from rhizomes of Acorus calamus collected from Jorhat, Assam; Munsyari and Pantnagar, Uttarakhand, India. EOs were studied for different pesticidal activities viz; nematicidal, insecticidal, and herbicidal activity. To study the synergistic effect of EOs on pesticidal activity, four combinations of EOs were prepared. Phenylpropanoids with β-asarone as the main compound were identified in all collections with varying percentages. Its contribution was found to be 85.8% in Munsyari EOs followed by 74.3% in Pantnagar and 62.6% in Assam collections. All EOs exhibited dose-dependent in vitro nematicidal activity against Meloidogyne incognita in terms of immobility and inhibition of egg hatching. The activity was observed as maximum in the EO combination of all three collections (1:1:1) whereas minimum in the Assam collections. In insecticidal activity against Lipaphis erysimi and Selepa celtis, maximum mortality was observed in Munsyari collections. The oils were assessed for sprout inhibition activity in terms of seed germination inhibition, coleoptile growth of the shoot and root against Raphanus raphanistrum. Maximum seed germination inhibition, % shoot, and root growth inhibition were found in all collections EO combinations. To predict the possible mode of action and the structure-activity relationship between major compounds of EOs and biological activities, in silico molecular docking and ADME/Tox studies were performed. The docking results revealed the mode of action of proteins of insects, nematodes, and weeds and were found in support of in vitro experiments. The study may be helpful for the development of herbal-based pesticides after proper clinical trials.
