Platycladus Orientalis Leaf Extract -------- A Natural Plant Hair Growth Active Ingredient
Platycladus orientalis leaf extract is an active substance extracted from the dried branches and leaves of Platycladus orientalis (L.) Franco, a plant in the Cupressaceae family. It has antitussive, expectorant and antiasthmatic effects.
Platycladus orientalis leaf extract is a pure natural plant extract derived from Platycladus orientalis leaves. It can unblock the scalp so that nutrients can be better absorbed by the hair roots, stimulate and care for the hair stems, prevent shedding, and promote the normal growth of hair to prevent hair loss. Hair growth effect. This is because Platycladus orientalis leaf extract activates hair mother cells and promotes blood circulation, reviving hair follicles with diminished hair growth ability, promoting blood circulation and supplementing nutrients to play the role of hair nourishment and hair growth.
[Source Plant] Platycladus orientalis is the twigs and leaves of Platycladus orientalis, an evergreen tree of the Cupressaceae family. The stems and branches are cylindrical, reddish brown; varying in length, densely branched, flat branchlets, 1 to 2 mm in diameter. The leaves are small and scale-like, alternately opposite, attached to the branches, dark green or yellow-green. It is brittle and easy to break. The smell is fragrant and the taste is bitter and slightly pungent.
[Habitat distribution] Evergreen trees, up to 7 meters high. Many Chemicalbooks are cultivated in gardens, and some grow wild. Branchlets flat. The leaves on old branches are scale-shaped and opposite; the leaves on young branches are lanceolate and arranged in a spiral. The flowers are unisexual, monoecious and born on the top of the branches. The cones are ovate, dark brown when mature, lignified and hard. The leaves are used as medicine and can be harvested in four seasons. They can be used fresh or dried in the sun. Roasted in charcoal can enhance the hemostatic effect.
[Harvesting and Processing] Mostly harvested in summer and autumn, cut off small branches, remove thick stems, and dry in the shade. During processing, the original medicine is sorted out and the miscellaneous branches are obtained, which are the "Arborvitae leaves". Take the clean leaves of Platycladus orientalis, put them in a pot and stir-fry over high fire until the surface is brown and the inside is brown, spray a little water, take it out and dry it, which is called "Arborvitae charcoal".
Chemical composition:
The leaves contain 0.6 to 1% volatile oil. The main component of the oil is α-thujone, including thujene, fechone, pinene, and caryphyChemicalbookllene. ), camphor, bornyl acetate, terpene alcohol, etc.; flavonoids include citrin, quercetin, myricin, cypress biflavonoids, cypress biflavonoids, etc. The crude total flavonoid content of fresh Platycladus orientalis leaves is 1.72%. It also contains tannins, resins, vitamin C and other ingredients.
Extraction method
1. Microwave extraction: Microwave has an obvious synergistic effect on extracting flavonoids from Platycladus orientalis leaves, reducing the amount of extractant, shortening the extraction time and improving the yield. It has the advantages of time saving, high efficiency and energy saving, thereby reducing the extraction cost. , which is superior to the traditional direct heating extraction method in many aspects. The most suitable process conditions are: φ (ethanol) 60%, material-liquid mass ratio 1:20, microwave time 4min, microwave power 385W. A verification test was conducted under this process condition, and the yield of Platycladus orientalis leaf extract was as high as 5.905%. Microwave extraction can greatly shorten the extraction time, reduce the amount of extractant, and increase the extract yield.
2. Extraction liquid type: In the Chemicalbook process of extracting flavonoids from Platycladus orientalis leaves using methanol, ethanol or ethyl acetate as the extraction liquid, extraction time and extraction temperature are the main factors that affect the extraction effect. Using methanol as the extraction liquid, the optimal extraction plan is: extraction time 6 hours, extraction temperature 70oC, liquid-to-material ratio 8:1, and total flavonoid yield 8.450%. Using absolute ethanol as the extraction solution, the optimal extraction plan is: extraction time 6 hours, extraction temperature 85 degrees Celsius, liquid-to-material ratio 10:1, and total flavonoid yield 7.422%. Using ethyl acetate as the extraction liquid, the optimal extraction plan is: extraction time 6 hours, extraction temperature 90oC, liquid-to-material ratio 6:1, and total flavonoid yield 6.748%. Comparing the three extraction solutions, the total flavonoids extracted using methanol as the solvent has the highest yield, and the methanol extraction temperature is the lowest and the energy consumption is the least. Therefore, the extraction process using methanol as the solvent is the best.
Main functions
1. Antibacterial effect: Platycladus orientalis leaf extract contains flavonoids and phenolic components such as cypress biflavonoids and kaempferol. It has antibacterial effects. The MIC value against fungi is 0.14~9.2mg/ml, and it has significant effects on Candida. Antibacterial effect, it has inhibitory effect on Staphylococcus aureus, catarrhalis, dysentery bacilli, typhoid bacilli, diphtheria bacilli, group B Streptococcus, anthrax, etc.
2. Anti-free radical effect: Alcohols, phenols, steroid compounds and other components in Platycladus orientalis leaf extract also have strong antioxidant effects, which can effectively remove free radicals in pigment cells, so that pigment cells damaged by free radicals It is slowly repaired and inhibits the regeneration of skin spots.
3. Anti-inflammatory effect: Platycladus orientalis leaf extract contains flavonoid glycosides and condensed tannins. Traditional Chinese medicine is used externally to assist in the treatment of burns, seborrheic dermatitis, hemostasis, etc.
4. Hair growth effect: Platycladus orientalis leaf extract has a dilating effect on the blood vessels of isolated rabbit ears. It can inhibit excessive sebum secretion, improve microcirculation, and strengthen hair follicles to prevent hair loss, stop hair loss, and grow hair.
