Tel: 013-8995990 •* Email : [email protected] It is a well-accepted fact that consumption of fresh fruits play a key role towards lowering the risk associated with chronic diseases such as cancer. Bouea macrophylla (in English known as Gandaria or Plum mango) is a tropical fruit tree native to Southeast Asia and commercially grown in the ASEAN regions (Malaysia, Thailand and Indonesia). Kundang tree produces fruits, which look alike, a small mango but much smaller. [1] • To determine the cytotoxicity and apoptotic effects of Bouea macrophylla Identification of new antioxidants from natural sources has become an active sequential extracts against three human cancer cell lines(HTB43, MCF-7 area of research, as a number of natural products, such as flavonoids, and MDA-MB-231). phenolics isolated from plants and foods have shown potent antioxidant activity. [2] Kundang has attracted our interest because of recent traditional claims that it have been found to protect against colon, breast, leukemia and prostate cancers. Besides, unripe and ripe kundang fruits posses’ significant amounts of nutrients and can be explored for commercial purposes Cell Lines HTB43 MCF-7 MDA-MB-231 Solvents (IC50 : µg/mL) (IC50 : µg/mL) (IC50 : µg/mL) Hexane 34.36±16.50* 59.07±5.76* 123.35±28.65* Chloroform 21.14±6.97* <250 <250 Methanol 18.65±2.94* <250 <250 Water 29.32±5.80* <250 <250 Fresh Bouea macrophylla were collected after being identified and confirmed by a plant taxonomist. The seeds were separated from the pulp dan dried in Cytotoxicity screening using MTT oven for 24 hours. Dried B.macrophylla seed were then grinded and extracted sequentially using different solvents (Hexane, Chloroform, Methanol and Water). HTB43 MDA-MB-231 MCF-7 All extracts were studied for its in vitro cytotoxicity and apoptotic effects against three human cancer cell lines (HTB43, MCF-7 and MDA-MB-231). All cells were seeded in 96-well plates at a density of ~10000 cells per well. Cells were then incubated for 24 hours with the extracts and screened using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Most effective concentration were screened for apoptosis induction in cells using Hoeshst stain. Hoechst 33342 was added to a final concentration of 2 μg/ml and the plate incubated for 45 minutes. Cells were imaged using white light set on Cell Reporter. Apoptotic cells images under white light by Cell reporter Our results indicate that the extracts has promising anticancer activity and causes loss in cancer cell viability by activating the apoptotic process. These findings also suggest that B. macrophylla may have novel therapeutic applications for the treatment of different cancer types. 1. Yang, H., Dong, Y., Du, H., Shi, H., Peng, Y., & Li, X. (2011).

Many assertions in the literature about the origins of particular species are found to be without empirical basis. In the absence of other data, comparative linguistics is an important source for tracing the spread of some fruits. Contrary to the Pacific, it seems that many of the fruits we now consider characteristic of the region may well have spread in recent times.

PASARIBU1, SOBIR2 and FITMAWATI3* 1Departement of Biology, North Sumatera University, Medan, Indonesia 2Center for Tropical Horticultural (PKHT), Bogor Agricultural University, Bogor, Indonesia 3Department of Biology, Riau University, Pekanbaru, Indonesia *Corresponding author’s email: [email protected] Email addresses of co-authors: [email protected], [email protected], [email protected] SUMMARY The major distribution of Bouea spp from the family Anacardiaceae is common in Malaysian region. The genus Bouea has three species B. Marcophylla, B. oppositifolia, and B. poilanei. Morphological variations were found in Bouea in various regions of Indonesia. This study aims to review the genetic diversity and grouping of Bouea spp in Indonesia using morphological markers. A total of 75 accessions of B. macrophylla and 30 accessions of B. oppositifolia obtained from 13 provinces in Indonesia observed with variations using 31 and 81 characters, respectively as morphological markers. Result of the observations were then cluster analyzed using the program NTSYS version 2.02 and confirmed using principal component analysis (PCA). Results revealed that morphological markers which can distinguish Bouea from other plants were opposite leaves pattern and purle seeds. Morphological markers that distinguished B. macrophylla with B. oppositifolia were leaf size, fruit size, fruit shape, fruit color, flesh color, and shape of the leaf axillary bud. Cluster analysis showed that B. macrophylla has similarity coefficient of 0.77 to 1.00 which is sub-divided in seven major groups with coefficient of 0.93.

Kundang fruit (Bouea macrophylla Griffith) is very popular in Malaysia and other ASEAN countries. The fruit is traditionally believed to impart potential health benefits, but no scientific information is available on the antioxidant compounds or the antioxidant activities in unripe and ripe kundang fruits. Materials and methods. Unripe and ripe kundang fruits were freeze-dried and subjected to three different types of solvent extraction (methanol, ethanol and distilled water). Freeze-dried samples were individually evaluated for antioxidant compounds (total pheno- lics, tannins, flavonoids and flavonols) and antioxidant activities (ferric reducing antioxidant power assay/FRAP assay, ABTS−+ assay and DPPH. free radical-scavenging activity assay). Results and discussion. High contents of phenolics, tannins and ascorbic acid were found in unripe fruits (extracted with methanol), whereas flavonoids and flavonols were high in ethanolic extracts. Anthocyanins were the highest in ethanolic extracts of ripe fruits. In addition, methanolic extracts of unripe fruits showed the highest antioxidant capacity [16,290.91 µM Fe (II) 100 g−1], with 77.69% DPPH inhibition and 99.76% ABTS.+ radical scavenging activities. Conclusion. This study clearly indicated that solvents tend to influence the extractability of antioxidant compounds.
