4. Chemical Ingredients and Benefits of Plants
Pumpkin contain the carotenoid (betakaroten), Vitamin A and C, mineral,
fats and carbohydrates.
Two phenolic glycosides compounds have been isolated from the seeds of Cucurbita moschata are (2-hydroxy)phenylcarbinyl 5-O-benzoyl-beta-D-apiofuranosyl(1–>2)-beta-D-glucopyranoside (1) dan 4-beta-D-(glucopyranosyl hydroxymethyl)phenyl 5-O-benzoyl-beta-D-apiofuranosyl(1–>2)-beta-D-glucopyranoside (2) (Li et al., 2009).

Five new phenolic glycoside compounds cucurbitosidesA—E (1—5), isolated from the seeds Cucurbita moschata are 2-(4-hydroxy)phenylethanol 4-O-(5-O-benzoyl)-β-D-apiofuranosyl(1→2)-β-D-glucopyranoside (1), 2-(4-hydroxyphenyl)ethanol 4-O-[5-O-(4-hydroxy)benzoyl]-β-D-apiofuranosyl(1→2)-β-D-glucopyranoside (2), 4-hydroxybenzyl alcohol 4-O-(5-O-benzoyl)-β-D-apiofuranosyl(1→2)-β-D-glucopyranoside (3), 4-hydroxybenzyl alcohol 4-O-[5-O-(4-hydroxy)benzoyl]-β-D-apiofuranosyl(1→2)-β-D-glucopyranoside (4) and 4-hydroxyphenyl 5-O-benzoyl-β-D-apiofuranosyl(1→2)-β-D-glucopyranoside (5) (Koike K., et al., 2005).

Phenolic glycosides compounds newly discovered is phenylcarbinyl 5-O-(4-hydroxy)benzoyl-beta-D-apiofuranosyl (1–>2)-beta-D-glucopyranoside selain 1-O-benzyl[5-O-benzoyl-beta-D-apiofuranosyl(1-->2)]-beta-D-glucopyranoside 2, cucurbitosides C 3 and A 4 (Li FS et al., 2009).

The leaves serve as a useful vegetable seeds and watermelon seeds to be used. Water fruit, useful as an antidote to the poison of venomous animals, while the seeds into a tapeworm medication. Flesh also contains anti-oxidants as cancer antidote. Pumpkin can also be used to cure inflammations, kidney treatment, fever, and diarrhea.

6. Mechanism of Anticancer Research

Has conducted research in silico enzyme acyl CoA diacylglycerol acyltransferase (DGAT, EC 2.3.120). Template use (PDB ID: 1K30).
