(L. chinensis) was developed. This was the first time to use  a structure-guided method development strategy 2D-HILIC 

× RPLC system.

Name of flavonoid that isolated from the Lobelia chinensis Lour are as follow:
1. apigenin 7-O-rutiboside
2. luteolin
3. lobetyolin
4. diosmin
5. linarin

Resluts: Four new flavonol-lignan heterodimers (1–4), together with nine known flavonoid derivatives (5–13) 

were isolated from this plant for the first time. Among them, some compounds exhibited moderate anti-prostate 

cancer and hepatoprotective activities.

Conclusion: Compounds 1, 2, 5, and 6 showed anti-prostate cancer activities using the LNCaP prostate cancer 

cells with IC50 values of 17.84, 33.26, 54.13, and 81.55 μg/mL, and compounds 3, 4, 8, and 9 exhibited 

moderate hepatoprotective activities, respectively.

In this journal, they isolated 2 compounds from stem bark of Alstonia boonei, which is a very tall tree widely found in west Africa. 

The method that the researchers used to isolate the compound is through column chromatography.

The isolated compound are:

1. tetrahydro-4-(7-hydroxy-10-methoxy-6, 14-dimethyl-15-m-tolylpentadec-13-enyl) pyran-2-one 

2. isobutyryl acetate

Some of my thoughts after finishing this task from week 3 to week 14: 
In this diversified planet, there are too many compounds in the nature yet to be discovered and studied for their beneficial characteristics. Therefore, I really found that a quote from Aristotle can best suites the journey of our group throughout week 3 to week 14 in discovering new compound each week. The quote is "The more I know, the more I don't know".
