Abstract
Many bioactive materials have been isolated from marine microorganisms, including alkaloids, peptides, lipids, mycosporine-like amino acids, glycosides, and isoprenoids. Some of these compounds have great potential in the cosmetic industry due to their photo-protective, anti-aging, and anti-oxidant activities. In this study, sarmentosamide (1) was isolated from marine-derived Streptomyces sp. APmarine042, after which its capacity to decrease skin aging was examined in-vitro. Sarmentosamide (1) was found to significantly reduce UVB-induced matrix metalloproteinase-1 (MMP-1) expression in normal human dermal fibroblasts (NHDFs) by inhibiting the extracellular signal-regulated kinase (ERK) and the c-Jun N-terminal kinase (JNK) phosphorylation, which are regulatory pathways upstream of MMP-1 transcription. Additionally, we confirmed that sarmentosamide (1) decreased tumor necrosis factor-alpha (TNF-α), induced MMP-1 secretion in NHDFs, and exhibited free-radical scavenging activity, as demonstrated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. Therefore, our study suggests that sarmentosamide (1) could be a promising anti-aging agent that acts via the downregulation of MMP-1 expression.

Abstract
Olea europaea L. is historically one of the most important trees of the Mediterranean countries. Increasing scientific interest regarding its fruits, leaves and olive oil has led to the elucidation of several phytochemical and biological characteristics. However, the phytochemical and biological studies regarding olive flowers remain limited. The aim of the present study was the phytochemical characterization of olive flowers' hydroalcoholic extract from Greek variety Lianolia, the effective isolation of the major secondary metabolites and evaluation of their inhibition activity against tyrosinase, elastase and collagenase. UPLC-HRMS/MS analysis was used to investigate the chemical composition of hydroalcoholic extract resulting in the identification of sixty-three secondary metabolites witch mainly belong to phenilethanoids, triterpenoids, flavonoids and secoiridoids. The orthogonial combination of Centrifugal Partition Chromatography and preparative HPLC in the same purification process led to the isolation of nine major compounds of the extract including two triterpenic acids, two flavonoid glycosides and five secoiridoid derivatives. From them, oleofloside A and oleofloside B are new natural products. Although, the hydroalcoholic extract and isolated secoiridoids exhibited weak or no inhibition activity towards tyrosinase and elastase, they exhibit remarkable anti-collagenase activity with 2΄-ethoxyoleuropein being the most active compound.

Abstract
Three new acylated phenylethanoid glycosides, kurroaosides A (14), B (15), and C (16), and a new acylated cucurbitane-type triterpene glycoside, kurroaoside D (17), were isolated from a methanol extract of the rhizomes of Picrorhiza kurroa Royle ex Benth. (Plantaginaceae) along with 29 known isolates including 10 acylated phenylethanoid glycosides (18-27), three cucurbitane-type triterpene glycosides (32-34), and a nortriterpene glycoside (35). The structures of these new compounds (14-17), including their stereochemistry, were determined based on chemical and physicochemical evidence derived from NMR and MS analysis. Among the isolates, acylated iridoid glycosides, picrosides I (8), II (9), III (10), and IV (11) and 6-feruloylcatalpol (12), phenylethanoid glycosides (14-16), triterpene glycosides, cucurbitacin B 2-O-β-D-glucopyranoside (32) and 25-acetoxy-2-β-D-glucopyranosyloxy-3,16,20-trihydroxy-9-methyl-19-norlanosta-5-en-22-one (35), and an acetophenone glycoside, picein (36), significantly promoted collagen synthesis at 10-30 μM, with no cytotoxicity being observed at the effective concentrations. Furthermore, acylated phenylethanoid glycosides, calceolarioside A (19, IC50 = 69.2 μM), plantamajoside (20, 51.8 μM), isoplantamajoside (21, 76.8 μM), and scroside E (23, 65.5 μM), exhibited collagenase inhibitory activity equivalent to that of positive agents caffeic acid (75.6 μM) and epigallocatechin 3-O-gallate (75.4 μM).

Abstract
Inhibition of matrix metalloproteinases (MMPs), which degrade collagen and elastin in the dermis of normal skin, is a key strategy for anti-skin aging. In this study, we identified five low-molecular-weight (LMW, <1 kDa) MMP-1-suppressive peptides in feather keratin hydrolysate (FKH) obtained by anaerobic digestion with an extremophilic bacterium. FKH was first subjected to ultrafiltration, followed by size-exclusion chromatography and liquid chromatography/electrospray ionization tandem mass spectrometry analysis. Chemically synthesized peptides identical to the sequences identified suppressed MMP expression in human dermal fibroblasts (HDFs). To investigate the impact of the MMP-1-suppressive peptides on the signaling pathway, we performed antibody array phosphorylation profiling of HDFs. The results suggested that the peptide GGFDL regulates ultraviolet-B-induced MMP-1 expression by inhibiting mitogen-activated protein kinases and nuclear factor κB signaling pathways as well as histone modification. Thus, LMW feather keratin peptides could serve as novel bioactive compounds to protect the skin against intrinsic and extrinsic factors.

Abstract
This paper describes the use of 1H NMR profiling and chemometrics in order to facilitate the selection of medicinal plants as potential sources of collagenase inhibitors. A total of 49 plants with reported ethnobotanical uses, such as the healing of wounds and burns, treatment of skin-related diseases, rheumatism, arthritis, and bone diseases, were initially chosen as potential candidates. The in vitro collagenase inhibitory activity of hydroalcoholic extracts of these plants was tested. Moreover, their phytochemical profiles were analyzed by 1H NMR and combined with the inhibitory activity data by an orthogonal partial least squares model. The results showed a correlation between the bioactivity and the concentration of phenolics, including flavonoids, phenylpropanoids, and tannins, in the extracts. Considering the eventual false-positive effect on the bioactivity given by tannins, a tannin removal procedure was performed on the most active extracts. After this procedure, Alchemilla vulgaris was the most persistently active, proving to owe its activity to compounds other than tannins. Thus, this plant was selected as the most promising and further investigated through bioassay-guided fractionation, which resulted in the isolation of a flavonoid, quercetin-3-O-β-glucuronide, as confirmed by NMR and HRMS spectra. This compound showed not only a higher activity than other flavonoids with the same aglycone moiety, but was also higher than doxycycline (positive control), the only Federal Drug Administration-approved collagenase inhibitor. The approach employed in this study, namely the integration of metabolomics and bioactivity-guided fractionation, showed great potential as a tool for plant selection and identification of bioactive compounds in natural product research.

Abstract
Tilapia skin gelatin hydrolysates (TSGHs) were prepared by simulated gastrointestinal digestion and separated by gel filtration and semi-preparative reversed-phase high-performance liquid chromatography. The anti-photoaging effects were evaluated using an ultraviolet radiation B (UVB)-induced mouse embryonic fibroblast (MEF) photoaging model in vitro. Three fractions from TSGHs with high inhibitory intercellular matrix metalloproteinase-1 (MMP-1) activities and reactive oxygen species (ROS) production were obtained. Three key peptides, GYTGL, LGATGL, and VLGL, were identified, and their C terminate was Gly-Leu. Three peptides were synthesized and exhibited a significant inhibition of intercellular MMP-1 activity and ROS production. Furthermore, three peptides inhibiting MMP-1 activities were evaluated through their docking of S1' and S3' active pockets of MMP-1. Hydrogen bonds and C terminate Gly-Leu played important roles. Finally, the protective effects of three peptides on intercellular collagen in UVB-induced MEFs were compared. Our results indicated that tilapia gelatin peptides exhibited potential activities to prevent and regulate photoaging.

Abstract
Metalloproteases are a family of zinc-containing endopeptidases involved in a variety of pathological disorders. The use of flavonoid derivatives as potential metalloprotease inhibitors has recently increased.Particular plants growing in Sicily are an excellent yielder of the flavonoids luteolin, apigenin, and their respective glycoside derivatives (7-O-rutinoside, 7-O-glucoside, and 7-O-glucuronide).The inhibitory activity of luteolin, apigenin, and their respective glycoside derivatives on the metalloproteases MMP-1, MMP-3, MMP-13, MMP-8, and MMP-9 was assessed and rationalized correlating in vitro target-oriented screening and in silico docking.The flavones apigenin, luteolin, and their respective glucosides have good ability to interact with metalloproteases and can also be lead compounds for further development. Glycones are more active on MMP-1, -3, -8, and -13 than MMP-9. Collagenases MMP-1, MMP-8, and MMP-13 are inhibited by compounds having rutinoside glycones. Apigenin and luteolin are inactive on MMP-1, -3, and -8, which can be interpreted as a better selectivity for both -9 and -13 peptidases. The more active compounds are apigenin-7-O-rutinoside on MMP-1 and luteolin-7-O-rutinoside on MMP-3. The lowest IC50 values were also found for apigenin-7-O-glucuronide, apigenin-7-O-rutinoside, and luteolin-7-O-glucuronide. The glycoside moiety might allow for a better anchoring to the active site of MMP-1, -3, -8, -9, and -13. Overall, the in silico data are substantially in agreement with the in vitro ones (fluorimetric assay).

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The top flowering aerial parts of the Hypericum species are traditionally used to prepare ointments to heal cuts and burns. Sometimes even the fruits are used for these purposes. Hypericum androsaemum L., commonly known as tutsan or shrubby St. John's Wort, is a Mediterranean medicinal plant which has been traditionally used to prepare an ointment for treating cuts and wounds. AIM OF THE STUDY To evaluate the extracts obtained from H. androsaemum red berries as functional ingredients for skin care formulations. MATERIALS AND METHODS The methanolic extract was obtained by Soxhlet extraction while the aqueous extract was prepared by decoction; their composition was determined by HPLC analysis. Their biological activities were measured in terms of proliferation and migration of human fibroblasts, inhibition of collagenase activity, and immunomodulatory effects on human peripheral blood mononuclear cells (PBMCs). In addition, we evaluated their photostability by UV spectroscopy and their protective effects against APPH-induced hemolysis in red blood cells (RBC). RESULTS The polar extracts contained significant amounts of shikimic (108,143.7-115,901.3mg/kg) and chlorogenic acids (45,781.1-57,002.7mg/kg). The main components of these extracts made an important contribution to a significant increase in human fibroblast migration. Both extracts were also active as collagenase inhibitors, with the aqueous one showing a greater inhibitory capacity (IC50 value of 88.1µg/mL), similar to that of chlorogenic acid. The kinetic parameters determined for the enzymatic reaction revealed for both aqueous extract and chlorogenic acid an uncompetitive mechanism of inhibition. The methanolic extract showed important effects on PBMCs by modulating IL-6. Both extracts proved to be photostable in the UVA/B range and protected RBC against peroxidation at low concentrations. CONCLUSIONS H. androsaemum red berries were proven to contain phytochemicals that improve skin regeneration, hence potentially employable in skin care formulations.

Abstract
Context Phyllanthus emblica L. (Euphorbiaceae) (amla), Manilkara zapota L.P. Royen (Sapotaceae) (sapota) and silymarin are reported to contain antioxidant effects. However, information on other biological activities relating to the anti-aging properties is limited. Objective To compare in vitro antioxidants, anti-collagenase (MMP-1 and MMP-2) and anti-elastase properties as well as the phenolic and flavonoid contents of amla, sapota and silymarin as potential anti-aging ingredients. Materials and methods The ethanol amla and sapota fruit extracts were prepared by three cycles of maceration with 24 h duration each. The total phenolic (TPC) and flavonoid (TFC) contents were determined. The antioxidant capacity was evaluated by DPPH and ABTS assays. The effects of MMP-1, MMP-2 and elastase inhibitions were determined by using the EnzChek® assay kits (Molecular-Probes, Eugene, OR). Results Amla exhibited the highest in TPC (362.43 ± 11.2 mg GAE/g) while silymarin showed the highest in TFC (21.04 ± 0.67 mg QE/g). Results of antioxidant activity by DPPH and ABTS methods showed that amla possessed the most potent capacity with IC50 values of 1.70 ± 0.07 and 4.45 ± 0.10 μg/mL, respectively. Highest inhibitions against MMP-1, MMP-2 and elastase were detected for sapota with IC50 values of 89.61 ± 0.96, 86.47 ± 3.04 and 35.73 ± 0.61 μg/mL, respectively. Discussion and conclusion Test extracts offered anti-aging properties in different mechanisms. Amla showed the highest phenolic content and antioxidant property with moderate anti-collagenase. Silymarin exhibited measurable flavonoid content with anti-elastase effect. Sapota showed the highest collagenase and elastase inhibitions with moderate antioxidant effect. Thus, extracts might be added as a mixture to gain the overall anti-aging effects.

Abstract
The chemical composition and pharmacological activity of E. senticosus cultivated in Poland were investigated. Studies included the assay of TPC and TFC, 2D-TLC identification of phenolic acids, HPTLC-detection of antioxidants, and antioxidative, antileukemic, anti-MMPs properties of E. senticosus. The ethanolic extracts from the roots, spring leaves, fruits, and the chloroform extract from the roots were tested. The richest in polyphenols are the fresh fruits (57.5 mg/g), while in flavonoids the spring leaves (27.4 mg/g). The antioxidant ability both in extracts and single phenolic constituents were checked out by the measurement of the DPPH radical scavenging activity, iron (II) chelating and lipid peroxidation inhibitory activity. Using HPTLC-DB test eleutherosides B and E1 have been found as the phenolic antioxidants. Thirty six percent of apoptotic cells have been observed in Jurkatt 45 line by the treatment with the chloroform extract from the roots. Only the chloroform extract from the roots and the ethanolic one from the dried fruits have shown the inhibitory activities against MMPs. It is noteworthy, that our studies have been done for the first time, and the plant material has come from another geographical zone (Poland) than native (Asia).

Abstract
Aortic stiffness is an independent risk factor for development of cardiovascular diseases. Activation of renin-angiotensin-aldosterone system (RAAS) including angiotensin converting enzyme (ACE) activity leads to overproduction of angiotensin II (ANGII) from its precursor angiotensin I (ANGI). ANGII leads to overexpression and activation of matrix metalloproteinase-2 (MMP2), which is critically associated with pathophysiology of aortic stiffness. We previously reported that the whey peptide Isoleucine-Tryptophan (IW) acts as a potent ACE inhibitor. Herein, we critically elucidate the mechanism of action by which IW causes inhibition of expression and activity of MMP2 in aortic tissue. Effects of IW on expression and activity of MMP2 were assessed on endothelial and smooth muscle cells (ECs and SMCs) in vitro and ex vivo (isolated rat aorta). As controls we used the pharmaceutical ACE inhibitor - captopril and the ANGII type 1 receptor blocker - losartan. In vitro, both ANGII and ANGI stimulation significantly (P<0.01) increased expression of MMP2 assessed with western blot. Similarly, to captopril IW significantly (P<0.05) inhibited ANGI, but not ANGII mediated increase in expression of MMP2, while losartan also blocked effects of ANGII. Signaling pathways regulating MMP2 expression in ECs and SMCs were similarly inhibited after treatment with IW or captopril. In ECs IW significantly (P<0.05) inhibited JNK pathway, whereas in SMCs JAK2/STAT3 pathway, assessed with western blot. In vitro findings were fully consistent with results in isolated rat aorta ex vivo. Moreover, IW not only inhibited the MMP2 expression, but also its activation assessed with gelatin zymography. Our findings demonstrate that IW effectively inhibits expression and activation of MMP2 in rat aorta by decreasing local conversion of ANGI to ANGII. Thus, similar to pharmaceutical ACE inhibitor captopril the dipeptide IW may effectively inhibit ACE activity and prevent the age and hypertension associated rise of aortic stiffness.

Abstract
Based on the significant inhibitory activity toward matrix metalloproteinase-2 and collagenase noticed in preliminary studies, crude extracts of Rhodiola rosea were partitioned and chromatographed sequentially to afford three new compounds, 1,2,3,6-tetra-O-galloyl-4-O-p-hydroxybenzoyl-β-D-glucopyranoside (1), (E)-creoside I (2), and (R,Z)-2-methylhept-2-ene-1,6-diol (3), along with twenty-four known compounds (4-27). Their structures were determined by spectroscopic data analyses. All isolated compounds were subjected to bioactivity assays. In these, 1 specifically inhibited matrix metalloproteinase-2 activity with an IC50 value of 16.3 ± 1.6 µM, while its analogue 1,2,3,6-tetra-O-galloyl-β-D-glucopyranonoside (17) inhibited matrix metalloproteinase-2 with an IC50 value of 23.0 ± 4.8 µM. In the collagenase activity assay, the inhibitory effects of 1 and 17 at concentrations of both 20 and 40 µM were more potent than those of the positive control, 1,10-phenanthroline. In order to realize whether 17 could penetrate from the epidermal layer into the basal and dermal layers of the human skin to inhibit the activity of matrix metalloproteinase-2 and collagenase or not, a transdermal penetration test in nude and white mice skins was performed. Penetration percentages of 17 quantified by LC-MS were 27.8 % and 74.8 % in 24 hours, respectively.

Abstract
Expression of matrix metalloproteinase 9 (MMP9) is elevated in a variety of inflammatory and oncology indications, including ulcerative colitis and colorectal cancer. MMP9 is a downstream effector and an upstream mediator of pathways involved in growth and inflammation, and has long been viewed as a promising therapeutic target. However, previous efforts to target matrix metalloproteinases (MMPs), including MMP9, have utilized broad-spectrum or semi-selective inhibitors. While some of these drugs showed signs of efficacy in patients, all MMP-targeted inhibitors have been hampered by dose-limiting toxicity or insufficient clinical benefit, likely due to their lack of specificity. Here, we show that selective inhibition of MMP9 did not induce musculoskeletal syndrome (a characteristic toxicity of pan-MMP inhibitors) in a rat model, but did reduce disease severity in a dextran sodium sulfate-induced mouse model of ulcerative colitis. We also found that MMP9 inhibition decreased tumor growth and metastases incidence in a surgical orthotopic xenograft model of colorectal carcinoma, and that inhibition of either tumor- or stroma-derived MMP9 was sufficient to reduce primary tumor growth. Collectively, these data suggest that selective MMP9 inhibition is a promising therapeutic strategy for treatment of inflammatory and oncology indications in which MMP9 is upregulated and is associated with disease pathology, such as ulcerative colitis and colorectal cancer. In addition, we report the development of a potent and highly selective allosteric MMP9 inhibitor, the humanized monoclonal antibody GS-5745, which can be used to evaluate the therapeutic potential of MMP9 inhibition in patients.

Abstract
Osteosarcoma is the most common primary malignancy of the bone cancers. In the Chinese population, the crude extract of Corni Fructus (CECF) has been used as Traditional Chinese medicine to treat several different diseases for hundreds of years. In the present study, effects of CECF on inhibition of migration and invasion in U-2 OS human osteosarcoma cells were examined. CECF significantly inhibited migration and invasion of U-2 OS human osteosarcoma cells. We also found that CECF inhibited activities of matrix metalloproteinases-2 (MMP-2) and matrix metalloproteinases-9 (MMP-9). CECF decreased protein levels of FAK, PKC, SOS1, MKK7, MEKK3, GRB2, NF-κB p65, COX-2, HIF-1α, PI3K, Rho A, ROCK-1, IRE-1α, p-JNK1/2, p-ERK1/2, p-p38, Ras, p-PERK, MMP-2, MMP-9, and VEGF in U-2 OS cells. Results of this study indicate that CECF may have potential as a novel anticancer agent for the treatment of osteosarcoma by inhibiting migration and invasion of cancer cells.

Abstract
CONTEXT Longkong [Lansium domesticum Corr. (Meliaceae)] is a popular tropical plant producing economic edible fruits found mainly in Southeast Asia. However, limited information is available concerning anticancer activity of Longkong. OBJECTIVE To investigate anticancer activities in human mouth epidermal carcinoma (KB) of Longkong extracts. MATERIALS AND METHODS Various parts of Longkong which was collected from Northern and Eastern of Thailand were extracted by the hot and cold processes using water, chloroform, and methanol. The extracts were tested for anti-oxidative activities and anti-proliferation as well as matrix metalloproteinase inhibition on KB cells. RESULTS The hot water extract of seeds from Northern region (NSEWH), the cold water extract of old leaves from Northern region (NOLWC), and the hot chloroform extract of young leaves from Eastern region (EYLCH) showed the highest free radical scavenging, metal ion chelating, and lipid peroxidation inhibition with SC50, MC50 and IPC50 values of 0.34 ± 0.03, 0.47 ± 1.60 and 0.86 ± 0.31 mg/ml, respectively. The hot and cold chloroform extract of young fruits from Northern region (NYFCH and NYFCC) exhibited anti-proliferation effect against KB cells with IC50 values of 603.45 ± 55.35 and 765.06 ± 46.19 mg/ml, respectively. NYFCC exhibited the highest pro- and active MMP-2 inhibition at 53.03 ± 2.65 and 31.30 ± 0.43%, more than all tested standard anticancer drugs except cisplatin. DISCUSSION AND CONCLUSION The cold chloroform extract of young fruits from Northern region appeared to contain anticancer active compounds against KB cells because of its high anti-proliferation and MMP-2 inhibition activities.

Abstract
CONTEXT Centella asiatica (L.) Urban (Apiaceae), a valuable herb described in Ayurveda, is used in the indigenous system of medicine as a tonic to treat skin diseases. OBJECTIVE Centella asiatica methanol extract and its ethyl acetate, n-butanol and aqueous fraction, were subjected for the evaluation of skin care potential through the in vitro hyaluronidase, elastase and matrix metalloproteinase-1 (MMP-1) inhibitory assay. MATERIALS AND METHODS The C. asiatica plant was extracted with methanol and fractionated with ethyl acetate, n-butanol and water. The enzymatic activities were evaluated using ursolic acid and oleanolic acid as standards. Isolate molecule asiaticoside was quantified in the crude extract and fractions through high-performance liquid chromatography (HPLC) and structural was characterized by liquid chromatography-mass spectroscopy (LC-MS) and ¹H nuclear magnetic resonance (NMR). Isolated compound was also evaluated for in vitro enzyme assays. RESULTS Extract exhibited anti-hyaluronidase and anti-elastase activity with IC₅₀ of 19.27 ± 0.37 and 14.54 ± 0.39 µg/mL, respectively, as compared to ursolic acid. Centella asiatica n-butanol fraction (CAnB) and isolated compound showed significant hyaluronidase (IC₅₀ = 27.00 ± 0.43 and 18.63 ± 0.33 µg/mL) and elastase (IC₅₀ = 29.15 ± 0.31 and 19.45 ± 0.25 µg/mL) inhibitory activities, respectively, and also showed significant MMP-1 inhibition (p < 0.05 and p < 0.01). DISCUSSION AND CONCLUSION n-Butanol fraction was found to be most effective among the all fractions from which asiaticoside was isolated and further quantified by HPLC. This work concludes that the asiaticoside from C. asiatica may be a prospective agent for skin care.

Abstract
The critical step in colorectal cancer progression and associated mortality is cancer invasion, which depends on two key gelatinase enzymes, matrix metalloproteinases-2 and -9. Dried longan ( Euphoria longana Lam.) seed is a rich natural source of antioxidant polyphenols.This study evaluated the effect of dried longan seeds on colon cancer cell invasion via gelatinase function and expression. Three dried longan seed fractions were collected by Sephadex LH-20 column chromatography. They showed a potent inhibitor on colorectal cancer cell invasion and gelatinase activity. The antigelatinase activities of fractions 1 and 2 were a direct effect via Zn²⁺ chelation, whereas fraction 3 modulated indirectly through suppression of zymogen activators. Among the fractions, only fraction 3 reduced the gelatinase expression, which was correlated with the levels of tissue inhibitor of metalloproteinase-1 and may as well involve the p38 mitogen-activated protein kinases and the c-Jun N-terminal kinase signaling pathways. This primary research has manifested and encouraged the anticancer properties of dried longan seed extracts with potential inhibitory effects on cancer cell invasion as well as antigelatinase activity and expression in colon cancer cells.

Abstract
The content of phenols (TPC), and the antioxidative, antileukemic and anti-MMPs properties of Eleutherococcus spp. cultivated in Poland are reported. The highest TPC was found in the spring leaves (20.3 - 37.2 mg/g). The spring leaves and roots of E. divaricatus had the strongest anti-DPPH activity (EC50 1.2 and 1.2 mg/mL), whereas the greatest ability of iron (II) chelating was shown by autumn leaves of E. setchuensis (EC50 0.3 mg/mL), and the ethanolic extract of E. gracilistylus roots showed the strongest lipid antiperoxidation activity (EC50 0.7 mg/mL). The highest number of apoptotic cells was observed in the Jurkat 45 cell line after treatment with the ethanolic extract of E. sessiliflorus roots (27%). Only the chloroform extracts of roots of E. gracilistylus and E. divaricatus showed the inhibitory activity against MMPs. Most of the studied species have a significant biological activity that is probably due to the presence of phenols. To the best of our knowledge, neither detailed phytochemical nor biological studies have been performed for most of the investigated species.
