Guttiferae diversity is found across the Indonesian archipelago. In order to elucidate the genetic diversity of mangosteen and its relatives, morphological and molecular analyses were conducted. The objectives for this study were: (1) to determine the relationships between mangosteen and its relatives; and (2) to confirm the true diversity of allotetraploid mangosteen relatives G. mangostana. Analysis was conducted using morphological and inter simple sequence repeat (ISSR) between 19 accessions of G. mangostana and their close relatives revealed. Diversity analysis was based on 212 polymorphic characters and 3 groups were formed. Group A consisted of Garcinia mangostana, Garcinia malaccensis, Garcinia celebica, Garcinia hombroniana and Garcinia porrecta; group B comprised Garcinia forbesii and Garcinia subellptica; and group C solely with Calophyllum inophyllum... The genetic similarity of Garcinia mangostana, Garcinia malaccensis and Garcinia celebica were 0.78 and 0.63. The epidermis cell observations around stomata cells on the lower surface of leaves revealed that Garcinia mangostana has the intermediate shape between Garcinia celebica and Garcinia malaccensis. It shows that there is a close relationship among Garcinia celebica, Garcinia malaccensis and Garcinia mangostana. It was determined that Garcinia malaccensis and Garcinia celebica were ancestors based on morphological and ISSR markers.

Based on the examination of 1915), belongs to family Guttiferae and genus herbarium collections and a literature review, Garcinia (Verheij, 1991). Almeyda and Martin there are 77 species of Garcinia in Indonesia.

It is important to determine the genetic Morphological analysis diversity and relationship between G. mangostana and several close relatives. Genetic Observations were taken for 29 morphological diversity can be determined using a characters consisting of 25 characters including morphological and molecular analysis such as flower, fruit, leave, latex color, 2 stomata ISSR. The advantages of ISSR markers include: characters and 2 epidermis cell character (Table (1) they are not being influenced by season and 2). Morphological characters of flowers, leaves environment; (2) require 5-50 ng template of and fruits were observed referring to IPGRI DNA per reaction; (3) represent loci throughout (2003). Documentation was done using a digital the genome; (4) can generate higher camera (Canon Powershot A480). Colors were polymorphism higher than RAPD (Gao et al., measured according to standard color chart of 2006); (5) produce inter species polymorphisms Royal Horticultural Society (5th Edition).

  • A Review on a Few Medicinal Plants Possessing Anticancer Activity Against Human Breast Cancer
    International Journal of PharmTech Research CODEN (USA): IJPRIF, ISSN: 0974-4304 Vol.9, No.3, pp 333-365, 2016 A Review on a few medicinal plants possessing anticancer activity against human breast cancer Jaikumar B, Jasmine R* PG Research Department of Biotechnology, Bishop Heber College, Trichy-17, India Abstract: Breast Cancer is known to be the second most common cause of death. So there has been intense research on various plant resources to develop novel anticancer agents against breast cancer.Herbal medicine is one of the most commonly used complementary and alternative therapies (CAM) by people with cancer. Some studies have shown that as many as 6 out of every 10 people with cancer (60%) use herbal remedies alongside conventional cancer treatments. There are many different types of herbal medicines and some of them overlap with foods. Commonly used plants include Echinacea, St John’s Wort, green tea and ginger. From the past several years, medicinal plants have been proved to be an important natural source for cancer therapy with fewer side effects. There are many natural cytotoxic drugs available, which needs further improvement and development of new drugs. An attempt has been made to review some medicinal plants used for the prevention and treatment of cancer. This article considers a few medicinal plants used anticancer activity against breast cancer cell line(MCF- 7). It will be helpful to explore the medicinal value of plants and for new drug discovery from them for the researchers and scientists around the globe. Keywords: Medicinal plants, Anticancer, MTT assay, MCF-7 cells. Introduction Cancer is a general term applied of series of malignant diseases that may affect different parts of body.

This book may not be reproduced in whole or in part without the prior written permission of the copyright owner. ii Foreword I am delighted to write a Foreword to the Book ‘Diversity of Garcinia species in the Western Ghats: Phytochemical Perspective’ edited by my student Dr. K. B. Rameshkumar who took Garcinia imberti as a subject for his doctoral studies. It gives me all the more pleasure and gratification to see that he continued with his studies on Garcinia species of the Western Ghats along with his students and colleagues. Unlike many other doctoral students, he kept alive his passion for the studies on Garcinia and the present book is the outcome of his dedicated efforts during the last one and a half decades. Pursuit of science is a passion and unravelling the subtleties of nature is an ecstasy which fulfils the inner urge for quest and discovery. The genus Garcinia is important by virtue of their reputation in traditional medicines, established pharmacological activities, diversity in chemical structures and potential nutritional properties. Despite recent progress in phytochemical and pharmacological studies on Garcinia species world over, significant gaps still exist concerning the exploration of the vast data on phytochemical diversity of Garcinia species.

Number of species and density of trees with more than 10 cm in diameter was 86 species and 698 trees/ha, while small tree of 2-10 cm in diameter was 100 species and 5043 trees/ha, respectively. The most abundant trees were Blumeodendron elatriospermum (47 trees/ha), Cyatocalyx biovulatus (39 trees/ha), Blumeodendron tokbrai (32 trees/ha), Lithocarpus encleisacarpus (30 trees/ha) and Syzygium chlorantha (30 trees/ha) with greater number of individual at smaller diameter classes. The most diverse families are Euphorbiaceae, Annonaceae and Dipterocarpaceae represented mostly by small-sized trees ranging between diameter 2-30 cm and rarely exceeding dbh 60 cm. Key words: peat swamp forest, floristic composition, Mensemat, West Kalimantan. Introduction Most of the peat swamp forest around Sambas Regency; West Kalimantan has been disturbed due to land conversion and logging. Some of the disturbed peat swamp areas were drained by artificial canals and have been converted into agricultural land, such as for rubber, coffee, pineapple and other fruits plants.

Thank you. For nurturing scientific thinking in me, for being the most supportive supervisor one can imagine, and for a lot of reasons that would be difficult to list. Your immense knowledge and ideas in many different aspects of this field lead to discussions that give me perspective on the questions we are asking and always leave me instigated about research.
