Hypericum perforatum compound ingredient fruit contains lignans categories: forsythia glycosides (forsythin, phillyrin), forsythia aglycone (phillygenin), right-handed turpentine phenol (pinoresinol), D-glucoside Pinoresinol (pinoresinol-β-D -glucoside); flavonoids: rutin (rutin); styrene derivatives: forsythia fat glycosides (forsythoside) A, C, D, E, forsythia Cornus wood glycosides (suspensaside), salidroside (salidroside) ; ethylcyclohexylamine alcohol derivatives: spine wood glycosides (cornoside), forsythia cyclohexanol (rengyol), different forsythia cyclohexanol (isorengyol), etc., still contain triterpenoids: betulinic acid (betulinic acid) ursolic acid, oleanolic acid and so on. Hypericum perforatum habits initiation ability, after stumping in piles or Lunar Hypericum perforatum extract, can breed initiation, rapid increase in the number of ramets, increasing distribution range. Forsythia branches are not strong growth year after year, turnover is faster, with increasing age, the initiation of the branches and the initiation of Hypericum perforatum extract spur professional production branches issued its growth are decreasing, and spur growth by diagonally into the level of growth. According to the survey, 8 -12 years old plants, four years of annual sprouted branches spur the most, and then gradually decreased. Cong high magnitude and forsythia branches show little change in different ages. Forsythia branches replacement fast, branches grow new shoots after initiation, scoliosis gradually outward slanting, so even though the plant continues to spur new pumping raw food grade Hypericum perforatum extract, but the height will remain at the same level. Hi light, there is a certain degree of shade tolerance; cold; drought-resistant thin, the fear of floods; the soil is not optional; strong pest resistance.
