and how can i get x,y coordinate values boundary B{k}
clear;
close all;
i1=imread('76.jpg');
i1=rgb2gray(i1);
i2=im2bw(i1,.4);
i2= wiener2(i2,[5 5]);
i2=imfill(i2,'holes');
%i2=~i2;
m=bwperim(i2);figure,imshow(m);
e=length(B);
labeledImage = bwlabel(i2, 8);
blobMeasurements = regionprops(labeledImage, i1, 'all');
imshow(i2)
hold on
set(gcf, 'Position', get(0, 'ScreenSize'));
for k = 1:e
boundary = B{k};
plot(boundary(:,2), boundary(:,1), 'g', 'LineWidth', 0.2)

Perhaps you want to poly2roi() ?

[x,y] coordinate values for the boundary are already in B{k} for each k.
If you want the all together in one array, but without any indication of where any of the boundaries ends, use
vertcat(B{:})

You never defined B. It looks like it should have come from a call to bwboundaries(i2). See my tutorial for an example: http://www.mathworks.com/matlabcentral/fileexchange/25157-image-segmentation-tutorial-blobsdemo
