Ltd. is an ISO9001&14001 certified factory focus on manufacturing herbal extracts and botanical extracts as the ingredient for dietary supplements since 2000.Based on natural TCM herbs and plants in Sichuan, Maoyuan's GMP practice plant share the world with andrographis extract, camptothecin and other extracts. Maoyuan has OHSMS, advanced processing and testing facility, innovation system and a group of talented and skilled staff. MAOYUAN focus on following main products: Andrographis (Paniculata) extract, originates from herb Andrographis Paniculata, an annual herbaceous plant in the family Acanthaceae.Powder andrographis extract is prepared from aerial part of herb andrographis paniculata by solvent ethanol. Maoyuan produces andrographis extract as standard extract. Maoyuan has a full spec of andrographolide from5% ~98% by HPLC. The most active ingredients of andrographis extract is andrographolide, at the same time, there's other ingredients present in andrographis extract: neoandrographolide, dehydroxyandrographolide and 14-deoxyandrographolide, especially in the andrographis with SPEC 5% -50% . 2. Rutin is a flavonoid, also known as rutoside, sophorin and quercetin-3-O-rutinoside. Rutin is chemically described as the glycoside between disaccharide rutinose and quercetin, another flavonoid. Origin: Flower buds of Sophora japonica CAS NO.?153-18-4 Molecular Formula: C27H30O16 Molecular Weight: 610.51 Specification: 95% ?by UV? Capacity: 3tons per month Appearance? greenish yellow needle crystal powder Part of the plant used: flower bud Extract Sovents: water Extraction Methand: Standard In house:rutin?95% by UV(NF-11) Maoyuan�s rutin is extracted from SOPHORA JAPONICA BUD, rutin is a SOPHORA JAPONICA BUD extract. Most the standard extraction rutin is from Sophora japonica bud, and some of the ratio extraction rutin is from other natural resouces such as buckwheat. 3. Milk Thistle ?dry?extract, originates from milk thistle or Cardui Mariae.Milk thistle extract has approximately 4�6% silymarin and consists of about 65�80% silymarin (a flavonolignan complex) and 20�35% fatty acids, including linoleic acid. Maoyuan produces milk thistle extract as standard extract. Product?Milk Thistle extract Specification?Milk Thistle P.E. 80% Capacity: 3 tons per month Appearance: Yellow Brown powder Packing: 1kg/foil bag or25kg/drum 4. Berberine Hydrochloride, originates from Bark of Phellodendron chinense Schneid. Berberine Hydrochloride has the weak effect on the inhibition of bacteria including Shigella, Escherichia coli, Staphylococcus aureus and can reduce the number of bacteria on the surface of bacteria so that it can�t attach to the body cells and decrease the gastric and duodenal gastrointestinal ulcers. Natural Origin: Bark of Phellodendron chinense Schneid Molecular Formula: C20H18CLNO4�2H2O Molecular Weight: 407.85 CAS NO.?633-65-8 Specification: 98-99% Testing Method: titration Appearance: Yellow crystalline powder Particle size: 95% 80 Mesh 5. (S)-(+)-Camptothecin (CPT) is a cytotoxic quinoline alkaloid originated from camtotheca acuminata or Nothapodytes pittosporoides(Mappia).Camptothecin was discovered in 1966 by M. E. Wall and M. C. Wani in systematic screening of natural products for anticancer drugs. Product (S)-(+)-Camptothecin CAS# 7689-03-4 Molecular Formula C20H16N2O4 Molecular Weight 348.43 Spec 95% , 98% , 99% (HPLC) Single impurity less than 0.5% generally, or <0.1% as required Camptothecin is the natural starting material of Irinotecan HCl. Camptothecin is the natural starting compound of 10-Hydroxycamptothecin.It is the natural starting ingredient of 7-Ethyl-10-Hydroxycamptothecin(SN-38)and Topotecan HCl.Compound camptothecin is a featured product for Apoptosis research.
