Humic substances are commonly found in decaying organic matter including plants, animal residues, sewage and soil. Although fulvic-acid accounts for ∼90% of all substances and its biological significance recognized for many years, there is still minimal scientific understanding the claims of its biological properties. However, these formulations contain numerous toxic elements that make their use clinically impossible. Recently, there has been development of a pure form of fulvic-acid, carbohydrate derived fulvic-acid (CHD-FA) that has been shown to be safe to use clinically and absent from environmental contaminants known to be harmful to the host. The aim of this study is to evaluate the effects of fulvic-acid on different cancer cells. Hep3B, HT29 and PC3 cells were treated different concentrations fulvic-acid for 48 and 72 h and cell proliferation was performed MTT test. Changes in the mRNA levels of apoptotic genes were also analyzed in PC3 cells. Fulvic-acid inhibited the proliferation of all the cell lines used in this study determined by MTT analysis. Specifically, Hep3B cells were found to be most sensitive for 48-hour application with 1.58–2.43 μg/μL IC50 value. Additionally, fulvic-acid significantly upregulated the apoptotic genes at mRNA levels compared to non-treated control group.

The fungus Cercospora rosicola produces abscisic acid (ABA) as a secondary metabolite. We developed a convenient system using this fungus to determine the effects of compounds on the biosynthesis of ABA. Inasmuch as ABA and the gibberellins (GAs) both arise via the isoprenoid pathway, it was of interest to determine if inhibitors of GA biosynthesis affect ABA biosynthesis. All five putative inhibitors of GA biosynthesis tested inhibited ABA biosynthesis. Several plant growth retardants with poorly understood actions in plants were also tested; of these, six inhibited ABA biosynthesis to varying degrees and two had no effect. Effects of plant growth retardants on various branches of the isoprenoid biosynthetic pathway may help to explain some of the diverse and unexpected results reported for these compounds. Knowledge that certain inhibitors of GA biosynthesis also have the ability to inhibit ABA biosynthesis in C. rosicola indicates the need for further studies in plants on the mode of action of these compounds.

부식질 농도가 매우 높은 지하수로부터 humic acid (HA) 와 fulvic acid (FA)를 분리 정제한 후 각각의 물리·화학적 특성을 조사하였다. 원소분석, 자외선/가시광선과, 적외선 스펙트럼분석 및 ^(13)C-NMR 분광법 HA와 FA의 구조 및 작용기를 확인하였다. 또한 양성자 교환 능력과 분자 크기분포 측정 실험을 통하여 HA와 FA의 특성을 비교하였다. 이 실험에서 분리 정제한 HA와 FA는 문헌에 나타난 수용성 부식질의 특성 외에 산출지 특성을 나타내며, 상당한 양성자 교환능력을 갖는 다분산계 임을 확인하였다.

这篇文章在喝水集中了于对铝种形成的 fulvic 酸和腐殖的酸的影响。包括剩余氯和 pH 价值的集中的因素被担心了。在实验调查的铝种类包括了无机的 mononuclear，器官的 mononuclear， mononuclear，聚合物，可溶，并且推迟的形式。铝种形成上的 fulvic 酸和腐殖的酸的效果主要取决于他们的分子的重量，这被发现。有分子的重量的 Fulvic 酸不到 5000 多尔顿几乎没在铝种形成上有小影响；当有比 5000 多尔顿大的分子的重量的 fulvic 酸和腐殖的酸将增加可溶的铝的集中时，显著地在 0.5 mg/L 下面在集中弄平(象 TOC 计算) 。铝种类，在礼品有比 5000 多尔顿大的分子的重量的 fulvic 酸和腐殖的酸，在有分子的质量的 fluvic 酸的礼品是比那更稳定的有反应时间的不到 5000 多尔顿，和改变的很少。在 pH 范围 6.57.5 以内，可溶的铝与有机物尤其是在水里增加了。当剩余氯的集中增加了， fulvic 酸和腐殖的酸的效果变得弱。在腐殖的酸，有大分子的重量的 fulvic 酸，和铝之间的反应被认为是一个多有牙齿的协作过程。与铝 bioavailability 的考虑，减少 fulvic 酸和腐殖的酸的集中并且在 6.57.5 之中保留 pH 价值在喝水处理期间被推荐。
