Today, I measured the abs. of the May samples and now I have data from three 
developmental stages to put into a graph. I measured the melting point of 
the acquired pomiferin and osajin. I found out that the melting points are 
two low, which means that the isoflavones are impure. Right now I am drying 
out the samples with a vacuum and then I will once more measure the melting 
point. If that doesn’t work then I will recrystallize the isoflavones and 
see if I eliminated the impurities.
