Gen info
Impatiens is a genus of about 850-1,000 species of flowering plants, and together with the puzzling Hydrocera triflora, the genus makes up the family Balsaminaceae. Some of the species are closer to Hydrocera than the presumed congeners. Phylogenetic studies might suggest a need to split up Impatiens.

Botany

Anti-inflammatory: Cyclooxygenase-2 Inhibitory 1,4-Naphthoquinones from Impatiens balsamina L.: Study showed evidence supporting traditional
use of Impatiens balsamina for rheumatism, pain and swelling.(3)
Antipruritic / Antidermatitic: Extract studies in atopic dermatitis model NC mice showed IB to be effective for the prevention and treatment of atopic dermatitis. (5)
Antipruritic / Pericarp / Balsaminones: Dinaphthofuran-7,12-dione derivatives
, balsaminones A and B were isolated from the pericarp of Impatiens balsamina L. together with the known compound 2-methoxy-1,4-naphthoquinone. The compounds exhibited significant antipruritic activity.(6)
Antipruritic: In an animal study using Dextran T40 and compound 48;80 to cause histamine release and induce itching, the ethanol extract of I. balsamina significantly inhibited the scratching behavior. Kaempferol, quercetin and 1,4-naphthoquinone derivatives in Ib were demonstrated to show antipruritic effects. (8)
Anti-Tumor: Study isolated a final and
active
component, 2-methoxy-1,4-naphthoquinone, which showed an intensive in vitro anti-tumor activity against HepG2 cells. (7)
Antibacterial / Kaempferol / Acne Treatment: Study investigated the antibacterial activity of kaempferol isolated from Impatien
s balsamina, alone or in combination with erythromycin or clindamycin, against antibiotic resistant Propionibacterium acnes. Results showed the combination of clindamycin with kaempferol or quercetin showed greater synergistic effect than erythromycin with kaempferol or quercitin. The combination suggested a potential for acne treatment. (10)
Anti-H Pylori Activity: Study investigated the activity of I. balsamina on resistant strains of H. pylori. The acetone and ethyl acetate pod extracts of I. balsamina exhibited very strong anti-H. pyloric activity. (13)
Antihelmintic: Study of five seed oils, including I. balsamina, all exhibited moderate to significant anthelmintic activity against
Pheretima posthuma. (15)
Anticancer: An ethanol extract was investigated for anticancer and in-vitro cytotoxic activities against transplantable tumors and human cell line. Results showed significant antitumor and cytotoxic effects against DLA and human Cancer Cell line. (20)
Antioxidative / Flower Extract: Study on antioxidant activity of flower extracts showed the different extracts all have different activity, and the water extract showing the strongest. (21)
Antimicrobial Efficiency of Various Extracts: Study evaluated the in vitro antimicrobial activity of leaf and root extracts of Impatiens balsamina against selected microbial pathogens. Results showed the ethanol and chloroform extracts to have excellent antimicrobial activity against all the test microorganisms. (22)
Histoprotective and Anti-Tumor Activity: Histological assessment was done on the anti-tumor promoting activity of a crude flower extract and isolate 2-methoxy-1,4-naphthoquinone (MeONQ) using the modified 2- stage mouse skin carcinogenicity assay. Results showed the crude extract and isolate MeONQ exhibit histoprotective effects on the pancreas, stomach, duodenum, and spleen of tumor-induced mice indicating anti-tumor activity. (23)
Mosquito Larvicidal: Study evaluated the larvicidal potential of various crude extracts of Impatiens balsamina against Anopheles stephensi, Aedes aegypti, and Culex quinquefasciatus. The highest larvicidal effect was observed in the leaf methanol extract. Results suggest a promising alternative to synthetic insecticides in mosquito control programs. (24)
Phytoremediation / Naphthalene: Study analyzed the accumulation of naphthalene in parts of I. balsamina and soil samples. Naphthalene concentration in the soil samples was reduced, while it was increased in the I. balsamina stem. Results suggest Impatiens balsamina could be used to remove naphthalene as organic contaminant in soil. (25)
Anti-H. pylori Compound / MeONQ: Anti-H. pylori compounds isolated from Impatiens balsamina were evaluated for anti-H. pylori activity. 2-methoxy-1,4-naphthoquinone (MeONQ) and stigmasta-7,22-diene-3β-ol (spinasterol) were isolated from the pods and roots/stems/leaves. MeONQ, which abounds in pods, showed dose dependent bactericidal activity against H. pylori. The activity was equivalent to amoxicillin. Results showed strong potential as candidate agent for eradication of H. pylori. (26)
Antimicrobial / MNQ: Study of 95% ethanol extract of dried aerial parts solated a single bioactive compound identified as 2-methoxy-1,4-naphthoquinone (MNQ). Against 18 test organisms, five gram positive and two gram negative bacteria, as well as eight fungi, including MDR strains, were highly sensitive to MNQ. A tea prepared by traditional method showed to have sufficient MNQ to account for its antimicrobial properties. (27)
Analgesic / Anti-Inflammatory / Leaves: Study of aqueous extract of IB leaves in animal models showed analgesic (tail flick method) and anti-inflammatory (carrageenan induced paw edema) effects, The effect was less than the standard drug reference used. (28)
Silver Nanoparticles / Bioreductant / Cytotoxicity / Flowers: Study reports the synthesis of silver nanoparticles using aqueous extract of IB flowers. The silver nanoparticles were evaluated for anti-proliferative/cytotoxic activities in five different types of human cancer cells. Differential anticancer properties of the biologically synthesized IBNPS may be due to different mechanisms of action. (see constituents above) (29)
AMPK-Activated Protein Kinase / Apoptosis in Human Oral Cancer Cells: Study evaluated the efficacy of a methanol extract from IB against HSC-2 human oral cancer cells. Results showed the methanol extract may be of therapeutic value for treating oral cancer, with a mechanism of action related to AMPK and t-Bid. (30)
Antinociceptive / Flowers: Study evaluated the antinociceptive activity of methanolic extract of flowers of IB using acetic-induced writhing, hot plate, tail immersion, and formalin test assays. Results showed strong dose-dependent peripheral and central antinociceptive activity in all the mice models. (31)
Enhanced Combined Phytoremediation / Petroleum Contaminated Soil: Study reports a plant-microorganism combined method of phytoremediation of petroleum contaminated soil. Inoculated petroleum degrading mixed microbes secretes chemicals helpful to IB. In return, IB releases photosynthesis products into the soil, to enhance antimicrobial activity and quality, to assist the organisms in phytoremediation. (33)
Anti-Hepatic Fibrosis / / Anti-Diabetic / Flowers: Study of flowers isolated eighteen compounds, seven new (3-9) and eleven previously reported. The compounds showed notable anti-hepatic fibrosis activity against murine Hepatic Stellate Cells and anti-diabetic activity against α-glucosidase. (34)
Phenolic Compounds / White Flowers: Study of methanolic extract of white flowers for biologically active compounds two new phenolic compounds (1,2) and eleven known phenolic compounds. The compounds were tested for neuroprotective activity by determining effects on nerve growth factor (NGF) and anti-neuroinflammatory activity.
