INTRODUCTION
Cardiovascular diseases are the leading
cause of death in Indonesia where one of
the common pathological substrate
underlying this process is atherosclerosis.
The OxLDL plays a key role in the
initiation and progression of
atherosclerosis (Ross, 1993). One of thepotentially atherogenic properties of
OxLDL is its cytotoxicity to the cells of the
artery wall

INTRODUCTION
Statins remain the first-line therapy for
preventing atherosclerotic cardiovascular
diseases, but undesirable side effects have
received much attention (Rosenson, 2004),however, some of them showed the
disadvantages, such as being hepatotoxic and
increased the blood sugar level. So the search
for new and safe antiatherosclerotic drugs hasprompted researchers to investigate the efficacy
of natural products (Wang et al., 2006).

SEARCH FOR LOWERING
CHOLESTEROL
Search from Marine and Terrestrial Natural Products
(Medicinal Plants (Jamu), Jelly Fishes or Fermented
Microbes)
In the past mostly was conducted using animal model,
classical pharmacology.
Anticholesterol activity was evaluated in the laboratory or
by anticholesterol kits.
Some were studied in silico (Computer aided drug
design)
Currently the search is studied through molecular
biology, such as, using enzyme of Hydroxy methyl
glutaryl Co A inhibitory evaluation.

Various Herbs Reported Active
for Lowering ChelsterolCurcuma xanthorrh iza Roxb.
The first useful anti cholesterol herb to be
discussed is Curcuma spp.
Our liver makes cholesterol as needed. If
we consume foods high in saturated fats,
the liver produces LDL cholesterol, which
is harmful to us. Curcuma rhizomes
extract works by limiting the production of
LDL cholesterol via a compound known as
curcumin, xanthorrhizol.

Capsicum
Capsicum is a well known spicy herb
commonly used in much more than just
chili. Its stimulating properties have the
ability to increase blood flow as well assluggish circulation along with it.
Researchers have determined that this
herb has been shown to lower both highcholesterol and high blood pressure.

Garlic
Garlic is another herb that has been used forcenturies in the treatment of many illnesses due
to its high content of sulfur compounds. It
contains roughly four times that of other
vegetables - cauliflower, onion and broccoli, alsohigh in sulfur. It keeps cholesterol levels in
balance by lowering LDL cholesterol levels, and
at the same time raising HDL cholesterol.
Garlic is a great herb. Indeed, besides being a
useful anti cholesterol herb, it has countless
other health benefits.

Chinese Red Yeast Rice Extract
Researchers have proven that monacolin,an ingredient in red yeast rice, has the
ability to inhibit cholesterol production by
halting enzymes in the liver responsible forproducing it.
Ginger
One more of the anti cholesterol herbs isginger, which helps to raise HDL
cholesterol as well as reduce both
triglyceride and overall cholesterol levels.

GARCINIA MANGOSTANA
-Mangostin sustains the cardiac mechanic
activities and decrease infarc area , prevent
the decrease of cardiac ATP and phospho
creatinine level in muscle cardiac
reperfusion. The xanthone protective effectis related to oxidative stress. n -Mangostin
prevents the protein oxidation induced by
reperfusion ulcer, lipid peroxidation(malondialdehyde and 4-hydroxynonenal
content)and the decrease of glutation.

CONCLUSION
Indonesia is rich on Natural Products for the development ofnew anticholesterol active compounds.
Various studies were conducted using classicalpharmacology and biology molecular
Dehydrolovastatin showed anticholesterol activity andincreased the HDL value in rodent experiment.
