General info:
Magnolia is an ancient genus. By the end of the 18th century, Magnolia species were described in China and Japan. The frist asiatic species were M. denudata, M. lilliflora, M. coco, and M. figo. Its bark has long been used in traditional Chinese medicine where it is called houpu.

Botany

Plant is a medium-sized shrub or a small tree growing to 3 meters. Leaves are smooth alternate, acuminate, elliptic-oblong, up to 16 centimeters long, dark green above, and waxy pale green below. Flowers are single, nodding, rounded like an egg or baby coconut, opening up with 6 white fragrant petals. Unlike most magnolias lacking nectar, Magnolia coco secretes a nectar-like substance inside the flower.

Distribution
– Native to China.
– Planted but not common in the Philippines.
– Propagated by seeds or marcotting.

Parts utilized
Bark, flowers, leaves.

Constituents
• Tha aromatic bark contains magnolol and honokiol, polyphenolic compounds that have antianxiety and anti-angiogenic properties.
• Study on leaves yielded a new compound, among eighteen compounds including fourteen lignans, one coumarin, and three alkaloids.
• Study yielded a new amide, magnolamide and a new lignan, magnolone, and 11 known compounds from the leaves of Magnolia coco.

Uses
Culinary
Flowers added to tea to enhance the fragrance.

Folkloric
– No reported folkloric medicinal use in the Philippines
– Used in Japanese and Chinese traditional medicine.
Used for insomnia, leucorrhea, productive coughing.
– Bark used for allergic and asthmatic conditions.
– Magnolia bark extracts also reported to inhibit bacteria responsible for dental caries and periodontal disease.

Study Findings
• LDL Oxidation Inhibition: Inhibition of low density lipoprotein oxidation by tetrahydrofurofuran lignans from Forsythia suspensa and Magnolia coco.
• Phytochemicals / New Constituents: Study yielded a new amide, magnolamide and a new lignan, magnolone with eleven known compounds from the leaves of Magnolia coco.
• Oral Hygiene Component: Magnolia bark extract in combination with a surface active agent is a component of a chewable oral composition with cleansing, breath freshening and antimicrobial benefits.(Patent pending)
• Essential Oil Constituents: The principal constituents of essential oils in M.coco from Guangxi are α-pinene, nerolidol, caryophyllene, germacrene D, bicyclogermacrene.
• Antioxidant Activity / Tetrahydrofurofuran Lignans: Tetrahydrofurofuran lignans from Forsythia suspensa and Magnolia coco were shown to exhibit antioxidant activity due to inhibition of oxidation of low-density lipoproteins (LDL).
